The results of having my aurora & scenic shots printed on aluminum have been WOW-With Out Words! The inks are dye-infused onto a specially-coated aluminum sheet and sealed with a gemlike UV coating that is both water and scratch resistant. We have commonly heard people say, "It's like looking through a window"...."Are these backlit?"...."They look so 3D." And the archival quality is out of this world (think century plus). This is a technological breakthrough and the results are in HIGH DEF!

On average, the sun rotates on its axis once every 27-28 days as seen from Earth. Therefore, sunspots, like those seen on the solar image to the left, are like a giant revolving firehose emitting energy into space for sometimes months at a time. After an active aurora night, mark that date on a calendar and in 27-28 days pay close attention to the sky. If that same sunspot (or coronal hole) is still active it will have rotated around with the sun and will be, once again, in geoeffective position (pointing toward Earth)....and hosing us with an enhanced flow of aurora-generating solar wind. Advertisement ## 11-Year Solar Cycle The sun has a heartbeat. Every eleven years or so it beats, and it beats hard. This is known as the solar cycle and is measured by the number of sunspots visible on the sun. The more sunspots, the more solar flare energy is being released into space (which means more aurora activity!). Sun Spots per Month SILSO data/image, Royal Observatory of Belgium, Brussels [Solar Cycle](solar-cycle.html) For 400 years, from the time of Galileo until now, we have been keeping track of the number of these sunspots and, as the trends show in these two graphs, this cycle is predictable. **Q:** Where are we now on the solar cycle? **A:** We're currently coasting down from the peak of the Solar Cycle - but history suggests this is when the sun throws some epic aurora parties. This magnetic reversal causes the sun to eject a lot of charged particles into the solar wind. This is good news for aurora hunters because the solar-released energy is the generating force of the aurora. The next few “peak phase” years should all be good. ## Best Months? Aurora Borealis season in northern polar latitudes (Alaska, northern Canada, Greenland, Iceland, Norway, Sweden, Finland and Siberia) runs from August-thru-April. These are the nights with darkness in them. During the summer months of May, June and July it is just too bright to see them in the far northland. Auroras can still be spotted south of about 50° latitude during the summer. Statistically, the equinox months of September and March are best for aurora activity. The winter months of October-thru-February are also good (there is definitely no shortage of darkness!). Mythbuster: Contrary to popular belief, it does not have to be cold to see the aurora, just dark and clear....and clear skies usually mean it’s cold, hence the association between auroras and chilly nights. ## What Time of Night? The peak hours are between 11pm and 2am, however, anytime it’s dark there is hope. I've seen the northern lights as early as 8pm and as late as 8am. ## Real-Time Listed below are some websites of organizations that monitor the sun, measure the solar wind in real-time (now), and make aurora predictions. In the explosive event that a coronal mass ejection (CME) is reported it's time to hop into action because this super-charged solar wind is traveling fast (maybe 3-to-5 million miles per hour). When this energy sweeps by the earth 1-to-3 nights later there is a very good chance of aurora activity. It pays to stay tuned in. ### Aurora Forecasting Tools Friday, 10/23/2026 ### Northern Lights Prediction Page ### Current Kp Index 2hr Max: **2** ### Planetary K-index Oct 20 Oct 21 Oct 22 Oct 23 Now Oct 24 Oct 25 Observed + forecast (hatched) ### Interplanetary Magnetic Field Bz-3 nT now Last 24h.

Great quick visual to show if auroras are tame or wild. - BsubZ reading. CRITICAL. You just want that to be a negative number, period. A negative polarity (-Bz) solar wind impacting the positive polarity Earth (that’s us, the big bar magnet in the sky) causes a coupling to occur and the energy flows through us. Negative & Positive cancels out allowing charged particles to stream toward Earth and blammo, 40-to-300 miles above our heads a wonder of the universe happens ~ in color ~ the AURORA!!! - KP index is the next thing I look at, the bigger the better!!! - Propagating sunspots, check out the black & white image of the sun in the lower part of this page. That’s a lot of sunspots! The sun is definitely ramping into solar maximum phase, which should mean more aurora activity. On any given night, I/we/you may or may not catch an aurora display due to an infinite amount of variables so, to me, it’s all about the hunt. --- # Northern Lights Webcams - Live Webcams in the Aurora Zone [Source](https://www.aurorahunter.com/northern-lights-webcams.html) # Northern Lights Webcams Hand-picked live webcams across the aurora zone - each one chosen for showing mostly sky, not road or rooftop, so you can actually judge conditions.

[Solar Cycle](solar-cycle.html) I always say the best year to hunt auroras is the year that we’re in... live for the now! The good news is we are currently in what I consider the peak phase of the Solar Cycle and sunspot activity has been generating some wild auroras. For those planning their own aurora hunt we advise going whenever it's convenient for you to spend the most amount of time as possible with your eyes on the sky. Whatever the year or weather prediction, we say just go for it! There’s no time like the present. This graph shows that my best aurora shots are spread out across all phases of the solar cycle. Predicting the exact month, week and night is the hard part and involves a lot of luck, due diligence and a night owl schedule so you are awake when the big show hits. ### 2. When are the best months to see the northern lights? Statistically, springtime (March/April) and autumn (September/October) contain the most “geomagnetically disturbed days” which means more aurora activity...although you're bound to see the lights in October, November, December, January and February if you spend enough time looking up. Average Number of Geomagnetically Disturbed Days Typical Equinox season 1932-2026 Data: GFZ Potsdam (Kp/ap index). Disturbed-day definition (Ap ≥ 25): Wilson & Hathaway, NASA/TP-2006-214711 ### 3. What time is best to see the Northern Lights? Midnight-to-2am is the best time to see the northern lights but they may occur anytime from sunset to sunrise. The later you can stay awake the better chance of getting to witness the grandeur of the northern lights. If you have clear earth weather and active space weather we highly suggest staying at your post until dawn. View our [Aurora Hunting Tips](aurorahunting-tips.html). ### 4. What causes the northern lights? The aurora borealis, also known as the northern lights, form when charged particles emitted from the sun (solar wind) get caught up in the earth's magnetic field and collide with atoms and molecules in our atmosphere. These collisions release little photons of light 50-300 miles high in our ionosphere. The rays that you see are our magnetic field getting illuminated by the incoming energy. It's like throwing dye in the sky. ### 5. What causes the different northern lights colors? The northern lights come in a variety of colors that are dependent on different gases getting excited/ionized by incoming charged particles. When oxygen atoms and molecules get bombarded they release green and red photons. When nitrogen molecules get struck they release the beautiful and rare purple light. More here: [What Are the Northern Lights](what-are-the-northern-lights.html). ### 6. Where do the northern lights occur? The best place to see the northern lights is in the far north like Alaska, Canada, Greenland, Iceland, Norway, Sweden, Finland and Siberia. In the southern hemisphere they have the **Aurora Australis**, the southern lights, which are best viewed from Antarctica. ### 7. Where in Alaska can I see the northern lights? In Alaska, the best place to see the aurora borealis is around Fairbanks. ### 8. Where in Fairbanks can I see the northern lights? If you are do-it-yourself adventurer, rent a 4-wheel drive SUV, get a north-facing hotel room ([Pike's Lodge](https://pikeslodge.com) is convenient) and then search out Ester Dome and Murphy Dome. [Chena Hot Springs is](https://www.chenahotsprings.com/) located 60 miles outside of Fairbanks and caters to the aurora viewer (wake-up calls, tours, hot springs). If you want to head even farther into the bush, [Bettles Lodge](https://bettleslodge.com/) is located right under the aurora oval, the most common place to see the auroras but you must fly in to this location. If you keep heading north along the Dalton Highway (Haul Road) you run into the Brooks Range with potential base camps in [Coldfoot or](https://www.coldfootcamp.com/) [Wiseman](https://www.arcticgetaway.com). ### 9. Where in Anchorage can I see the northern lights? The northern lights are less common at the Anchorage latitude compared to further north like around Fairbanks. To get the best angle on the northern sky around Anchorage try: - Pt. Woronzof & Earthquake Park (west end of Northern Lights Boulevard) - Anchorage Hillside (Glen Alps Trailhead, Flattop) If traveling north of Anchorage some viewpoints include: - Skyline Drive, Eagle River - Old Glenn Highway and Knik River Road - Hatcher Pass – both the Palmer side and the Willow side - Talkeetna is wonderful - Denali Viewpoint South – MP 134 on the Parks Hwy ### 10. Can we predict the northern lights? To predict the northern lights it helps tremendously to get a pulse on the different cyclic patterns that auroras have a tendency to follow. Lucky for us, humans have made great advances in aurora science in just the last few decades and there are several prediction tools at our disposal. More on [Northern Lights Forecast](northern-lights-forecast.html). ### 11. Does it have to be cold to see the northern lights? No! It is a myth that the northern lights happen only when it's cold. They happen year-round and since there is more darkness to see them in the winter people associate the cold winter with the auroras. I've seen them in August while wearing a T-shirt and shorts! ### 12. How long do the northern lights last? Anywhere from 10 minutes to all night long, depending on the magnitude of the incoming solar wind. "Coronal holes" consistently produce nice auroras but big solar flares and CMEs-coronal mass ejections are responsible for global-wide aurora displays…the BIG shows! ### 13. What is real-time solar activity? Real time is right now, the present, and many organizations are monitoring the sun in real time and on the lookout for solar activity. When there's a big solar flare, also known as a CME (Coronal Mass Ejection) an alert is posted because when that energy sweeps by the earth anywhere from 1-to-3 days later satellites can be damaged, cell phone coverage can be messed up and on rare occasions power grids can fail leaving people without electricity. Not good if it's deep winter. ### 14. What is a geomagnetic storm? Geo is earth – “geomagnetic” is the earth's magnetic field. When a gust of solar wind buffets the earth's magnetic shield and some of that energy comes streaming down our magnetic poles this is the science that creates the magic of the northern lights and is known as a “geomagnetic storm.” We have magnetometers and other types of instruments that record this incoming energy in real time and give us an instant heads-up that something could be happening in the skies overhead. ### 15. What is the Kp Index? The Kp Index is a 1-to-9 scale that quantifies disturbances in the earth's magnetic field. If you hear the Kp is over 4 or 5 it's good to have your eyes on the sky because we are probably in the middle of a geomagnetic storm, which means the northern lights could be out! ### 16. What are some good northern lights internet links? The Internet has a lot of cool links that provide an aurora hunter with an alert system (I still prefer the old-school method of just camping out under the stars… but if I'm in cell phone range it's hard not to take a peek at the iPhone!). NASA and NOAA provide a lot of information. SpaceWeather.com is a great starting point. View our [Aurora Borealis Links](links.html). ### 17. Is northern lights viewing best with a moon or no moon? I personally like moonlight because it lights up the foreground and makes the sky a deep blue instead of pitch black like with no moon. I watch the lunar phase very carefully. View our [Moon Phases](moon-phases.html) page. ### 18. How to photograph the northern lights? For starters set the camera on a tripod, crank the ISO up to 800 or 1600, set the f-stop wide open (lowest number like ƒ2.8) and start bracketing the exposure times. Try 5 seconds, 10 seconds and 20 seconds. If the picture is still black and underexposed then try 30 seconds and keep raising the ISO until something shows up on your LCD monitor. View our [Photographing the Aurora Borealis](photographing-the-aurora.html) page. ### 19. What kind of photo gear do you use to capture the northern lights? Here is a list of the equipment I use: #### Camera Bodies - Nikon D850 (FX-full frame for still images) #### Lens - Sigma 14mm/f1.8 Art lens - Sigma 20mm/f1.4 Art lens - Sigma 35mm/f1.4 Art lens - Nikon 16mm/f2.8 fish-eye lens - Nikon 24mm/f1.4 lens - Nikon 28mm/f1.4 lens - Nikon 17-35mm/2.8 wide-angle zoom lens - Nikon 28-300mm/f3.5 VR lens (for daytime use) - Tamron 150-600mm/f4.5-5.6 telephoto zoom lens --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Northern Lights Prediction](/northern-lights-prediction.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Blood Moon: Total Lunar Eclipse in Denali, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/blood-moon.html) [‹](/photos/anchorage-supermoon.html) # Blood Moon [›](/photos/catch-of-the-day.html) ![](_pix/jaypeg/blood-moon-salat.jpg) --- ## The “Blood Moon” Experience The total eclipse of the moon I witnessed on March 13, 2025 in Denali National Park, Alaska, was nothing short of ahhhmazing!

With that off the checklist, I turned my eyes to the stars while exploring this lake near Willow. The conditions were perfect; calm, warm (+50°) and no mosquitos so I went off the beaten path. I was drawn to a narrow & winding forest game trail and navigated through the bumpy tree roots, bear spray in hand, while whistling and occasional barking out “Yo moose, Yo bear” so as not to surprise any critters. When I emerged out of the thick forest and saw this unique spruce tree leaning into the Milky Way Galaxy, I gasped. I positioned my tripod right then & there, opened the camera shutter for several seconds, then used my little headlamp to illuminate the funky tree to bring out its character. Boom, one shot and I knew it was a keeper.

The late summer “fall” colors were splendid and we’d seen the auroras for three nights in a row. On this calm & clear evening I was extending my tripod for some nighttime photography when Shay called out, “Todd, the moon!” It had just started to rise through the trees so I had time to put on my telephoto zoom, focus, have a jaw-dropping WOW moment, and then click.

Around 1 am I crested a hill near the Arctic Circle and was thrilled to see moonlit, snow-encrusted spruce trees with a green shoot of auroras sprouting up from the eastern horizon. Time to hop into action! Snap, Crackle, Pop! The distant beanstalk grew into a jolly green giant that twisted the night away right up until the 5:45 am break of dawn.

September is a great month in the “Last Frontier.” You can drive, camp, catch some fall colors, and have equal night and day. March would be the best for those who like winter activities. October & November are quite good, December-thru-February are OK but definitely colder and darker, especially if you plan to travel the Interior (north of the Alaska Range). Please note that, contrary to popular belief, it does not have to be cold to see the aurora, just dark and clear. April is spring break-up which is pretty slushy and more often cloudy... but that doesn't mean the auroras can't be spotted! The hours of darkness are shorter though. The summer months of May thru mid-August are just TOO bright in Alaska to see the aurora. ## Where & How Fairbanks is probably your best starting point for spotting an aurora. [Chena Hot Springs](https://www.chenahotsprings.com/), located 60 miles out of town, is a very popular place**. **They cater to the aurora watcher and they have a fun hot springs and nice restaurant/bar to help entertain the spirit if it's cloudy. The more independent route would be to rent a car and get a hotel room somewhere in Fairbanks (or beyond). Get a north-viewing room so you can look out the hotel window and check if the auroras are coming in. Start looking for a green band as soon as it's dark. The peak hours are 10pm-2am but I've seen them anytime between dusk and dawn. If it's clear and you have a “green light” head up to Cleary Summit (Skiland), Ester Dome or Murphy Dome. A 4-wheel drive vehicle would be best for peace of mind. Bring very warm clothing, food, water and a cell phone. If you had car trouble or got stuck it's best to be prepared for the worst because if it's clear it's usually very cold. A parka, face-mask, big boots and those little chemically activated hand warmers would make the difference between a glorious night under the stars versus an “I just want to stay in my warm car/hotel” attitude. I know, I've definitely been there. Hope is always the key word when I'm on an aurora hunt. Bring books and things to keep yourself occupied because, as you probably already know, there are no guarantees. Pray for luck and luck comes to the patient ones. To fill your spare time you could research dog sled rides or check out the [World Ice Art Championship](https://www.icealaska.org/). Fairbanks has a big movie theater for those cloudy nights. ## Aurora Hunting Tools [Here is a quick set of tools](aurora-hunting-tools.html) to help you with your Aurora Hunting ## Good Luck & Happy Aurora Hunting! ![](_images/todd/sig.png) --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Epic Aurora & Natural Phenomena - Aurora Borealis Film [Source](https://www.aurorahunter.com/epic-aurora-and-natural-phenomena.html) # Epic Aurora & Natural Phenomena --- ## Todd's looking for a co-pilot,and that would be you!

Todd's looking for a co-pilot… and that would be you! ***Now available in High Def on Blu-Ray*** ![](_images/movies/epic-movie-front-sm.jpg) ![](_images/movies/epic-movie-back-sm.jpg) PERSONAL NOTE: The inspiration for creating this movie, the 2nd in my series, came after I spent five years obsessing on one of the coolest filming techniques in the world; Time-lapse photography. I learned a whole lot about natural processes by speeding them up with a camera & computer then observing how auroras, tides, clouds, the moon & stars all flow to their own rhythm and beat. Turbulent yet calming and sometimes downright Epic! And the music is so essential that when I find the right sound to go with the sights it just makes everything sing. ### Movie Info Running Time: Approx 40 min NTSC Coded for all world regions.

Use a cable release or set the self-timer to 2-seconds. Hands off to reduce vibrations. - **Lens:** A wide-angle lens (14mm-35mm) is preferred. - **Aperture:** An f-stop of f2.8 or faster (f2.8, f2.0, f1.8, f1.4) is best for nighttime photography. I prefer to shoot with a “wide open” aperture (lowest f-stop). If your lens is f3.5 or slower set the ISO higher to compensate. - **ISO:** With today's digital technology my preferred ISO is around 1600-2500. Sensors in the high-end full-frame cameras allow the ISO to be set even higher like 6400 and beyond. - **General:** A black picture means that it is under-exposed. If you have a digital camera just keep lengthening the exposure time or raising the ISO setting until something shows up on the LCD display. If you are shooting film, bracket the heck out of the exposure times for insurance. A ballpark setting for a fairly bright aurora would be: 3 or 4-second exposure, 28mm/f2.8 lens, ISO 1600. - **Headlamp:** A headlamp frees up your hands. A red headlamp saves your night vision. ## Dress for the Cold Practice your nighttime photography at home shooting the stars or the neighborhood streetlights. If you get lucky with the aurora you don't want to be stressing out on a camera. You want to be able to breathe deep and take in the whole experience. Patience and warm cloths help, too. The aurora is not related to air temperature, but clear skies usually mean chilly nights. Dress for success.

It was September in Alaska and we were on the tail end of our annual fall colors & aurora hunt and there was gold in them thar hills! But the crown jewel, Mt. McKinley, lay partially veiled behind a layer of clouds. After a couple of days of waiting for the clouds to clear with no luck we headed south, homeward bound for Anchorage. In the gray skies the wind was whipping the leaves off the trees at an alarming rate signifying the end of the season was near. ![](/_images/merch/alaska-gold-metal-triptych.jpg) Four days later our phone rang and the owner of the photo gallery in Talkeetna enthusiastically stated; “The Mountain's Out!” (thanks, Beth!). Two and a half hours later I was at my post as the magic hour of sunset was close at hand. I was amazed at how many leaves had dropped in just a few short days but the ones still hanging on radiated like golden nuggets in the setting sun. And over 50 miles away, jutting high into the clear blue skies, was the Alaska Range and its well-known trio of peaks (from left-to-right); Mts. Foraker, Hunter and Denali (20,310'). “Alaska Gold” as far as the eye could see. ![](/_images/todd/sig.png) Share: ### Photo Info Talkeetna, Alaska Nikon D300 with a Nikkor 28-200mm lens 1/20 sec, pano stitch, ƒ/13, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Anchorage Lights: Aurora Over the Chugach Mountains | Aurora Hunter [Source](https://www.aurorahunter.com/photos/anchorage-lights.html) [‹](/photos/alaska-gold.html) # Anchorage Lights [›](/photos/anchorage-supermoon.html) ![](_pix/jaypeg/anchorage-lights-salat.jpg) --- ## The “Anchorage Lights” Experience Green auroras stand out against the orange & blue twilight sky above Anchorage, Alaska, with Mts. Denali, Hunter & Foraker silhouetted 170 miles in the distance. This beautiful coloration was viewed from Powerline Pass in the Chugach Range on April 27, 2019 at 1:42 am. I love springtime auroras! Late April is not usually considered a very good aurora viewing time in Alaska because the window of darkness is only a few hours long and the extensive daylight of summer is right around the corner. And that’s what makes catching these springtime auroras feel extra special. This was one of my last chances for the season. Knowing exactly the shot I wanted, I wandered down a snowy trail below Flattop Mountain toward a pre-scouted location. I had to pick up my pace when, quite suddenly, a green aurora band I had my eyes on started to bend, twist and then climb into tall curtains. This was it! The moment when the pre-visualization all comes together: the shimmering lights of my hometown, the orange glow of a lingering sunset silhouetting the distant Alaska Range, a picturesque glacier-carved valley lined with cool mountain peaks, and a window in the trees creating a framework for the grand centerpiece, a majestic display of northern lights. What a spectacular night for a variety of “Anchorage Lights” to shine. ![](/_images/todd/sig.png) Share: ### Photo Info Anchorage, Alaska Nikon D850 with a 14mm lens 3s, ƒ/2.0, ISO 250 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Anchorage Supermoon: Full Moon Over Cook Inlet, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/anchorage-supermoon.html) [‹](/photos/anchorage-lights.html) # Anchorage Supermoon [›](/photos/blood-moon.html) ![](_pix/jaypeg/anchorage-supermoon-salat.jpg) --- ## The “Anchorage Supermoon” Experience A “supermoon,” one of the biggest and brightest full moons of the year, rises above the city lights of Anchorage, Alaska at dusk on February 19, 2019 at 7:53 pm while the Arctic Valley Star twinkles on the Chugach Range. This vantage point is looking east from Earthquake Park at the far end of Northern Lights Boulevard. ![](/_images/merch/anchorage-supermoon-metal-triptych-salat.jpg) ### Definition Supermoon On its elliptical orbit around earth this is about as close as the moon gets to earth (known as perigee) and is 221,734 miles away. A Supermoon is 8% wider and 16% brighter than an average full moon. ### About the Star… The star you see on the steep slopes of the Chugach Range (right side of photo) is at an elevation of 4000 feet above sea level. It is 300 feet in diameter (wide as a football field) and is made up of around 350 – 60 watt lightbulbs. From this viewpoint the star is located about 15 miles away on land controlled by Joint Base Elmendorf Richardson (JBER) and is maintained by military work crews. Every year, just after Thanksgiving, the 5-point star gets turned on and remains on until mid-to-late March when the last Iditarod musher crosses the finish line in Nome. ![](/_images/todd/sig.png) Share: ### Photo Info Anchorage, Alaska Nikon D850 with a Nikkor 28-300mm f/3.5-5.6G ED VR lens 1s, ƒ/7.1, ISO 800 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Catch of the Day: Humpback Whales in Kenai Fjords, AK | Aurora Hunter [Source](https://www.aurorahunter.com/photos/catch-of-the-day.html) [‹](/photos/blood-moon.html) # Catch of the Day [›](/photos/denali-fireweed.html) ![](_pix/jaypeg/catch-of-the-day-salat.jpg) --- ## The “Catch of the Day” Experience A big group of humpback whales use the bubble-net feeding technique in Alaska’s Kenai Fjords in Resurrection Bay on July 25, 2023. I was aboard a Major Marine Tours out of Seward and it was the first time I witnessed this amazing spectacle. The backdrop of the Chiswell Islands made it feel even more majestic. Whichever humpback whale that invented this cooperative feeding technique was brilliant! And a great coach too since it takes teamwork. The most experienced whale leads the charge by letting out a trumpeting call and starts circling a school of herring from below, all the while blowing out bubbles that corral the prey into a tight cylinder of water-space. The group follows suit then burst upward through the center of the bubble net with gaping jaws lined with baleen to gulp down and filter out this massive concentrated caloric source. They may eat a ton of food a day. It's binge-time! If you’re a herring and you think you slipped through the net, good luck dodging the seagulls. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Denali Fireweed: Wildflowers at Reflection Pond, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/denali-fireweed.html) [‹](/photos/catch-of-the-day.html) # Denali Fireweed [›](/photos/denali-spectacle.html) ![](_pix/jaypeg/denali-fireweed-salat.jpg) Share: ### Photo Info Denali National Park, Alaska Nikon D80 with a Nikkor 18-200mm lens 1/8 second, ƒ/14, ISO 100 --- ## The “Denali Fireweed” Experience It was another beautiful July morning in Denali National Park & Preserve and all 19,470 feet of Denali’s North Peak was out in full glory.

This was one of those stellar nights when you feel extra happy to be alive and out under the stars. The crisp Alaskan air was crystal clear, perfect for nighttime photography, and in this 15-second exposure the depth of field revealed is truly out of this world! In the foreground are the birch & spruce silhouettes along with the icy green glow of aurora light reflecting on the frozen Chulitna River. Next up is the snow-clad Alaska Range with its crown jewel, Denali, standing 4-miles high and 40 miles away. Beyond that the auroras appear to touch the mountains but that’s an illusion as the 50-to-300 mile high curtains of light wrap around the curvature of the earth 200-to-300 miles in the distance. It is now time to leave the earth far behind as we reach for the stars. The Milky Way, the spiral-shaped galaxy that we live in, contains billions of stars, some revealed here in that concentrated “arm” of starlight angling up to the left. From our home in the Orion Arm this is our winter view of the neighboring Perseus Arm in the outer reaches of our galaxy. These stars are thousands of light-years away and one light year = 6 trillion miles… 6,000,000,000,000 miles! If that’s not mind-blowing enough, do you see that white smudge in the red auroras above and to the right of Denali? That’s the Andromeda Galaxy (M31), also spiral-shaped, and is 2.5 million light-years away….which equals 15 quintillion miles! (a quintillion is 1018). Together this image connects “Alaska, the Last Frontier,” an awe-inspiring, earthly terrain to wander in with “Space, the Final Frontier,” an unfathomably huge expanse to imaginatively wonder in. ![](/_images/todd/sig.png) Share: ### Photo Info Denali Viewpoint South, Alaska Nikon D850 with a 14mm lens 15 seconds, ƒ/2.0, ISO 4000 ### Denali Stars on the web [Alaska Public Media ~ December 17, 2021 ~ Alaska aurora photographer celebrating 25 years of nocturnal lifestyle](https://alaskapublic.org/2021/12/17/alaska-aurora-photographer-celebrating-25-years-of-nocturnal-lifestyle/) --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Denali Wonder: Midnight Sun at Wonder Lake, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/denali-wonder.html) [‹](/photos/denali-stars.html) # Denali Wonder [›](/photos/dreamscape.html) ![](_pix/jaypeg/denali-wonder-salat.jpg) --- ## The “Denali Wonder” Experience I entered Denali National Park & Preserve, professional photography permit in hand, and drove down the gravel road in the drizzling rain.

[›](/photos/free-to-fly.html) ![](_pix/jaypeg/eureka-salat.jpg) --- ## The “Eureka!” Experience During the golden hour of 2 am, the darkest part of the night, I struck paydirt atop Eureka Summit along Alaska’s Glenn Highway on April 28, 2020 when colorful auroras pierced the late spring twilight. ![](/_images/merch/salat-eureka-pentych.jpg) Earlier that evening, as the sun was going down, I embarked on my last aurora hunt of the season and drove northeastward out of Anchorage. During this time of year in the northland, orange & blue twilight lingers all night long and that was the light I was banking on to create a canvas for the auroras to project their color upon. A 130-mile journey up the Scenic Byway later, I crested Eureka Summit with its commanding view to the north. At a half-past midnight I was very happy to see a subtle aurora band taking shape so I grabbed my camera & tripod and plunged into the snow. Surprisingly, the two feet of white stuff was frozen firmly and I could bootscoot & boogie across it without post-holing. Venus & the setting moon were accompanied by pinholes of starlight as I wandered freely through the open spruce forest. I caught a glimpse of a lynx bounding across the snow, so I felt the land was alive & well. A little before 2 am the aurora band was still barely visible but, in the span of just one-minute, a switch was turned on and a brilliant string of lights pulsed from horizon-to-horizon for a few minutes strong. I was so thankful I was in position... but then it began to fade down to almost nothing and threatened to fizzle out. I heard myself whisper out loud encouragingly, “C’mon, you can do it!” Moments later, much to my relief, a bright aurora glow developed within the orange sunset/sunrise and spikes of light surged higher & higher into the twilight blue sky. It was 2:07 am when my camera recorded those purplish aurora rays and I could literally feel the beauty. It was so crisp, calm, serene, ethereal and… rich. I stood there feeling like I had struck it rich ~ Eureka! ![](/_images/todd/sig.png) Share: ### Photo Info Eureka Summit, Alaska Nikon D800E with a Nikon 17-35mm f/2.8 lens 6 sec, pano stitch, ƒ/2.8, ISO 2000 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Goddess of Dawn: Rare Red Aurora Near Denali, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/goddess-of-dawn.html) [‹](/photos/go-deep.html) # Goddess of Dawn [›](/photos/heart-of-alaska.html) ![](_pix/jaypeg/goddess-of-dawn-salat.jpg) --- ## The “Goddess of Dawn” Experience The [aurora forecast](/northern-lights-prediction.html) was for quiet skies. I thought about staying home, but the northern lights are not always predictable and the call of the wild is unrelenting. It was late January, the heart, depth and soul of winter in Alaska. When I asked my wife, Shay, what kind of new aurora shot she would like to see, she replied, "How about some red auroras over Denali?" Whew! The challenge was on. I found myself at my old post, MP 135 on the Parks Highway. Four years earlier I had obsessed for 30 nights at this location trying to get a "hero shot." This time it happened on the third night, right at the crack of dawn. Jupiter was setting over the Ruth Glacier as the early morning alpenglow illuminated Denali. I couldn't believe my eyes when, out of the deep blue skies, a towering curtain of red and teal northern lights developed within the twilight's first gleaming. Castor & Pollux, the twin stars of Gemini, twinkled in the candy-like colors above the tall spruce trees while the 5-star pattern of Auriga the Charioteer graced the other side of the sky. This was a precious moment as the Aurora, **"Goddess of Dawn,"** unveiled her otherworldly artistry. *Geography:* This photo was taken looking northwest across the frozen Chulitna River braid plain at an elevation of 600 feet. About 40 miles away and rising almost four miles is Denali, meaning "The High One" in the native Athabaskan language. The prominent peak is the "South Peak" of Denali and is the highest point in North America at 20,310 feet. Although the auroras appear to touch the ground they are 50-300 miles high and 200-400 miles away. *Myth & History:* In Roman mythology, Aurora, the goddess of dawn, opens the gates of heaven every morning for Apollo, the sun god. In the late 17th century, the Italian astronomer Galileo used the name "Aurora" to explain the luminous glow in the nighttime sky. He believed that the dancing lights were caused by sunlight reflecting off the atmosphere during the coming dawn. This theory is no longer accepted but the name aurora lives on. ![](/_images/todd/sig.png) Share: ### Photo Info Mile 135 Parks Highway, Alaska Nikon FM with a Nikkor 35mm f/1.4 lens 4 seconds, ƒ/1.4, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Heart of Alaska: Heart-Shaped Aurora Near Glennallen, AK | Aurora Hunter [Source](https://www.aurorahunter.com/photos/heart-of-alaska.html) [‹](/photos/goddess-of-dawn.html) # Heart of Alaska [›](/photos/heaven-and-earth.html) ![](_pix/jaypeg/heart-of-alaska-salat.jpg) --- ## The “Heart of Alaska” Experience Two lovely aurora curtains meld together into the shape of a heart as they dance through the stars near Glennallen, Alaska on August 30, 2024 at 2:30 am.

This fall I pulled out the road atlas and spotted a dot that I had never been to before - Eagle, Alaska. Veering north off of the Alcan, I took the Top-of-the-World Highway to the Taylor Highway. A hundred plus miles of gravel later I stopped where the road stopped, right on the edge of the mighty Yukon River. I stepped out, took a deep breath of cool autumn air and instantly felt refreshed. The small town of Eagle and surrounding landscape has some very positive energy. I started exploring every avenue and eventually came to the old 1901 church. I was captivated. The small one-story building glowed with turn-of-the-century history as it sat on the bank overlooking the swift and mesmerizing river. A big 'ol birch tree, probably as old as the church, had grown healthy and tall next to it and had a children's swing hanging from a branch. I knew right then and there that, come nightfall, I would search here for that spiritual experience. Around 10pm the first green arc appeared on the northern horizon. Before long, tall colorful rays decorated the sky like a huge pane of stained glass. I began photographing the aurora from all angles while illuminating the church with every creative lighting technique I could think of. This photo turned out to my liking, and to be honest, is better than I had expected. Why? Because, after clicking the shutter open on my tripod mounted camera, I ran to the back side of the church and poofed the little steeple and church bell (look closely) with a hand-held flash unit. By the time I made it back to click off the camera it had become over a 30 second exposure, which is very long to me...but the film actually recorded some precious light that the retina in my eyes could not detect. I saw distinct and separate green auroral curtains with faint pink upper borders - the film saw and recorded the wonderfully deep purples, lavenders, and blues which fill in the entire sky. That light is there, we just can't see it all! This is where the title comes to me, **"Heaven & Earth."** Here on earth we have trees, churches, and rivers. Up there in the sky is heavenly beauty, some we can see, and some we cannot, but deep down inside we know it's there. ![](/_images/todd/sig.png) Share: ### Photo Info Eagle, Alaska Nikon FM with a Nikkor 28mm f/1.4 lens 20 seconds w/flash, ƒ/1.4, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Icelandic Flow: Aurora Over Godafoss Waterfall, Iceland | Aurora Hunter [Source](https://www.aurorahunter.com/photos/icelandic-flow.html) [‹](/photos/heaven-and-earth.html) # Icelandic Flow [›](/photos/kennecott-treasures.html) ![](_pix/jaypeg/icelandic-flow-salat.jpg) --- ## The “Icelandic Flow” Experience Meandering auroras flow around the moon and avoid a bank of clouds before dipping into Iceland’s roaring Godafoss Falls on April 15, 2022 at 2 am Greenwich Mean Time (GMT). It was Night #9 on my two-week Iceland odyssey and, although I’d seen a few minor aurora displays, I hadn’t experienced anything of this magnitude. As I cruised along the Ring Road near sundown looking for a campsite, I came upon Godafoss Falls and was instantly struck by the sheer beauty. The sky was predominantly cloudy but around midnight the auroras peaked through a cloud gap and I hustled to get some cool shots in the game bag before heavy clouds moved back in. And then the big one hit at 2 am when the sky suddenly opened back up and a huge aurora rush came shining through. For the second time that night, I found myself sprinting like an Icelandic horse to get into position above the falls when Holy Wow, With-Out-Words, the sky erupted into tight, multiple bands snaking together into curvalicious shapes! I was absolutely stunned at how bright & well-defined the lights were. This was the quintessential peak moment of the entire trip. I’ve been on a lot of aurora hunts in my life, but I don’t know if I’ve ever “worked” so hard to get the shot. I was 3,336 miles from my home in Anchorage, Alaska, living in a campervan, but the whole trip was a dream-come-true and this night alone made it totally worth the effort. ![](/_images/todd/sig.png) Share: ### Photo Info Godafoss Falls, Iceland Nikon D850 with a Nikkor 16mm f/2.8 fisheye lens 2s, ƒ/2.8, ISO 2000 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Kennecott Treasures: Aurora at Kennecott Mill, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/kennecott-treasures.html) [‹](/photos/icelandic-flow.html) # Kennecott Treasures [›](/photos/kiss-the-sky.html) ![](_pix/jaypeg/kennecott-treasures-salat.jpg) --- ## The “Kennecott Treasures” Experience Autumn was here. Ahhhhh. After a typical crazy Alaskan summer it's always nice to see darkness return to the skies - and with it, the Aurora! This years fall project was to explore the Kennicott area in the Wrangell / St. Elias National Park. Built in the early 1900's on a huge copper deposit, the Kennecott Mill Site (note spelling difference) has partially withstood the test of time...and partially weathered into a captivating ghost mine with a very nostalgic allure to it. The artistic appeal had me hooked, and with it, an uncontrollable desire to photograph the Aurora dancing over the rustic red structures. It was going to be a treasure hunt. On a September backpacking trip I didn't get lucky with the Aurora so October 1st found me once again driving down that 60 mile stretch of gravel road from Chitina to the McCarthy area. I parked at the Tram Station and now had to face a dilemma. After crossing the footbridge over the Kennicott River, how was I going to get 2 weeks worth of food and gear, probably a 150 pound load, up the little 5 mile gravel road to Kennecott. At this point I struck a great fortune - the operator of the Tram Station offered me his Subaru, which was on the other side of the river. Yes! (Thanks Randy!!). The vehicle also served as a huge bear-proof container to store my food in. I threw my sleeping pad in the back and that Subaru became my home away from home. On that very first lucky night, the treasure was uncovered. I drove up the hill to the mine, found my favorite northward viewing angle, set up both tripods & cameras, and cooked up some noodles. The sky was clear, and just as I finished up my meal, a green Auroral band materialized out of thin air, right over the mine! It got brighter and brighter....then faded....then returned with a few of its friends and soon four bands were dancing through the Big Dipper and over the mine. A full moon in the sky lit up the snow on nearby Mt. Donoho and on the surrounding Wrangell Mountains, but the mine was just not quite catching the moonlight. I thought it might be like this so I had thrown in my million candle-power spotlight. I plugged it into the Soob's cigarette lighter, and after clicking the camera shutter open, I would 'paint' the buildings with a beam of light for several seconds. I experimented a lot since this was the first time I've tried this technique but was quite happy with the results. From the very beginning this whole experience was truly treasurable and the photographic reward is depicted here in "**Kennecott Treasures**." ![](/_images/todd/sig.png) Share: ### Photo Info Kennecott Mill Site, Alaska Nikon FM with a Nikkor 24mm f/2.0 lens 10 seconds w/spotlight, ƒ/2.0, ISO 400 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Memorial Lights: Aurora at the Alaska Veterans Memorial | Aurora Hunter [Source](https://www.aurorahunter.com/photos/memorial-lights.html) [‹](/photos/kiss-the-sky.html) # Memorial Lights [›](/photos/moon-and-mars.html) ![](_pix/jaypeg/memorial-lights-salat.jpg) --- ## The “Memorial Lights” Experience Auroras light up the Alaska Veterans Memorial near midnight on January 30, 2022.

I was on a mission, bound & determined to witness the precious Harvest Moon & Mars alignment, and I urgently needed to find a gap in the clouds! I held tight to the steering wheel while my truck/camper rig was bucked around the highway by a supremely powerful wind. The Weather Service alert read “Travelers should watch out for 70-mile-per-hour gusts.” Seriously?! For a brief, uninspired & cloudy moment, I hung my head low and thought to myself, what bad luck… A millisecond later the lightbulb came on and with my head held high I said to myself; Self, high winds have the potential to cause radical CLOUD SHAPES! With renewed enthusiasm I cantered on until I broke on through to the other side (Doors), saw a gap in the clouds, and FINALLY got to see the Moon near the big bright dot as promised ~ Mars. Click, got it! Oh my, look at those clouds sailing through the conjunction and turning colors! Thank you lunar iridescence (when white moonlight gets refracted into different parts of the color spectrum). CLICK!!!!!!!!

Timing is everything, whether it's planned, or stumbled upon by pure luck. **"Morning Glory"** is a little of both. Late February 2003 found me [aurora hunting](/aurorahunting-tips.html) around Denali when I saw the first near-dawn moonset. The timing had been wrong for a photo opp. The Alaska Range was still in the earth's shadow as the moon, one day away from being full, set prematurely behind the dark peaks. On average, the moon sets 50 minutes later every day, so a quick calculation suggested the next morning held promise for a dynamic play of light. I put away my gear and got a good day's sleep. Tomorrow, I foresaw an opportunity to fulfill my Mission Statement: Be there. Preserve the moment. Share it. ### Be There From a vantage point near Hurricane Gulch Bridge on the Parks Highway I watched the clear northern sky all night long. Mt. McKinley was on my left to the west. As minutes turned to hours there was not even a whiff of an aurora, so I kept myself entertained by watching the big, now full, moon slowly arc its way up and over the sky. Around the wee hours of the morning time began to speed up. The moon was heading down to the west at an angle and the eastern horizon began to lighten. I wanted to align the moonset with Denali, but the angled path of the moon revealed that I was too far north. I fired up the truck and drove southward. The sky transitioned from black to a deep blue. I picked up my pace. Where's the optimal photo location?! Ten miles later the timing was becoming crucial, but a wall of tall spruce trees was impairing my view. Any further and the view would become completely obliterated by a closer set of mountains. I rounded a bend and saw a window in the roadside trees with Denali shining through. Shining?! At 20,310 feet, nearly four miles higher than me, the mountain was experiencing a glorious sunrise. I pulled off the side of the road, scrambled to the roof of my camper with tripod and camera in hand, took a deep breath . . . and began shooting. ### Preserve the Moment The rosy alpenglow was creeping down the sides of the mountain, basking every crevasse and cornice along the way with filtered sunlight. Due to the low angle of the incoming sunlight only the long wavelengths of red and orange, the warm tones, penetrate our atmosphere. High in the sky, the scattered short wavelengths of blue light were reflected in the deep shadows. All the while, the full moon was getting blasted by the full spectrum, which combines to form white light. What a play of sky, mountain and moon light! For those few brief minutes it all balanced out enough to be preserved on film. ### Share It The moon dipped out of sight behind the mountains and the alpenglow gave way to the bright sunshine of a new day. I gave a moment of thanks, and then crawled down from my perch, still feeling lofty as ever. This peak moment involved hours of growing hope, minutes of a spiritual experience, and the timeless afterglow of sharing it. Thanks for taking the time to share this experience with me. ![](/_images/todd/sig.png) Share: ### Photo Info Parks Highway, Alaska Nikon N80 with a Nikkor 80-400mm lens 1/15 second, ƒ/8, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Mysterious Moment: SpaceX Spiral in the Alaska Aurora | Aurora Hunter [Source](https://www.aurorahunter.com/photos/mysterious-moment.html) [‹](/photos/morning-glory.html) # Mysterious Moment [›](/photos/ninilchik-spires.html) ![](_pix/jaypeg/mysterious-moment-salat.jpg) Share: --- ## The “Mysterious Moment” Experience An illuminated blue whirlpool sails through the aurora and over Donnelly Dome near Delta Junction, Alaska, on April 15, 2023 at 1:54 am. What is it?! Trust me, at first I was totally bewildered! The shock of seeing this spiral-shaped apparition first appear on the northern horizon moving straight toward me and growing rapidly, until seven minutes later when it faded to the south, was one of the most bizarre experiences of my life. It wasn’t until two hours later when the auroras stopped dancing that I had time to research what the heck I’d seen. Turns out this phenomenon can be explained with rocket science. A SpaceX Transporter-7 mission that had launched southward on the Falcon 9 rocket three hours earlier from Vandenberg, California had sent a second stage rocket on a polar orbit to deploy its payload of 51 satellites. When finished, the second stage engine did some additional burns and perhaps jettisoned excess fuel while deorbiting. Water vapor in the exhaust froze into ice crystals and spiraled outward into grandiose arcs and became illuminated by high-altitude sunlight causing the bluish-white glow. Physicists say it may take as little as a few gallons of water to create this. This all happened as it passed over Alaska during a beautiful aurora display, stunning many night-watchers including myself. That short, mysterious moment in time when I witnessed the most bizarre thing I’d ever seen is what I’ll always remember.... the wondrous feeling of the unknown. p.s. for pointer stars – see the Big Dipper near the top end of the spiral? “Spill out of the dipper” and the last two stars point to the North Star to the right.

The September day was cool and drizzly but the landscape was emanating the warmth of autumn gold. We parked our rig at Reflection Pond (out by Wonder Lake) and I grabbed my camera gear. As I reached for the door handle I looked out my driver's side window and was taken aback. Not more than 10 feet away a brown bear was walking RIGHT by my door! The grizzly stared at me at point blank range as he/she sauntered on by. In a flash I went through a roller coaster of emotions: shocked-scared-relieved-excited! After calming down a bit we photographed *Ursus arctos* using its teeth to rake hundreds of blueberries into its mouth. This was the last chance for it to stock up on reserves before holing up for the big freeze. The foraging bruin ambled into the Wonder Lake Ranger Station and, perhaps sensing something was different, paused at the flagpole. It stood up on its hind legs and for a regal moment it appeared to be paying his or her respects to the American flag, which was flying at half-mast.

It was crystal clear and the northern lights were already taking shape so I fueled up my belly with food and went downstairs to tuck my wife into bed. I hadn't set my course for the night so I asked her where she thought I should go. In a sleepy voice she murmured, "Go...to...Lake...Hood...and...get...a...float...plane...shot." Wow, what a great idea! It was going to be an all-nighter on the Hood, the largest seaplane base in the world. Stardate: October 13, 2012. Many of the float planes had already been pulled from the water in preparation for the winter freeze-up but on the east shore (Lake Spenard side) I found this stunning red Cessna 195, a classic built in 1949 and held in high esteem in the aviation community (which is quite large in Alaska). At the stroke of midnight stormy space weather whirled up and sent waves of green auroras reflecting across the serene lake water. Folks behind me had stepped out of the Millennium Alaskan Hotel and, despite the glow of the Anchorage Int'l Airport in the background, we all were treated to a spectacular aurora display. No bright city lights were going to stop this show from going on! Many hours later I tucked my cold toes into bed and, half-awake, Shay whispered, "Did you get the shot?" Yeah, I think so...and then I dreamt the night away. *Acknowledgements: I'd like to thank "Captain Kirk," owner of Susitna Energy Systems for the permission to run with this shot.

What a refreshingly early treat! It was Night #14 of the aurora hunt. I had driven a thousand miles as I looped northward through Denali to Fairbanks then down to Delta Junction and Glennallen. It had been an exhilarating two weeks and I had seen plenty of auroras. Now I was on the home stretch to step back into my Anchorage lifestyle and kiss my wife hello. On the night I promised to be home, an encouraging aurora alert was announced on spaceweather.com. A coronal hole on the sun was pointing toward earth and hosing us down with a vast, aurora-generating dose of charged particles. Fortunately, my wife was very understanding and said, “You better stay out there!” When I spotted the first green band at 8 pm I knew something very cool was being newly minted….45 minutes later breath-taking auroras burst onto the scene as I kneeled on the edge of the clear ice and composed their reflection amidst delicate ice crystals that resembled popcorn. The hoarfrost-encrusted trees contributed another tasty element while the ridgeline of Pioneer Peak provided an iconic landmark. I do believe the auroras had saved the best for last on this trip and I am so thankful I was already clocked on and in position when the early bird special light was turned on! ![](/_images/todd/sig.png) Share: ### Photo Info Knik River Valley, Alaska Nikon D850 with a 14mm lens 4 seconds, ƒ/2.0, ISO 2000 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Polar Vortex: Spiral Aurora Near Trapper Creek, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/polar-vortex.html) [‹](/photos/pioneer-mint.html) # Polar Vortex [›](/photos/reach-for-the-stars.html) ![](_pix/jaypeg/polar-vortex-salat.jpg) Share: ### Photo Info Denali State Park, Alaska Nikon D850 with a 14mm lens 1.3s, ƒ/2.0, ISO 2000 --- ## The “Polar Vortex” Experience Auroras spiral out of control above the moon, mountains and a cabin near Trapper Creek, Alaska at around 2 am on the spring equinox, March 20, 2021. These auroras were big.... HUGE!!!! Earlier in the evening a wall of northern lights had stormed the sky then faded from view. This gave me a chance to regroup and discover this cool cabin in Denali State Park. The moon was setting over the Alaska Range when a second and even bigger wave of auroras consumed the sky. I was getting absolutely blown away by the variety of wild & bizarre shapes when this “Polar Vortex” of swirling energy developed. In over 30 years of aurora viewing, I had never seen an aurora spiral of this magnitude.

The Kenai Fjords and Resurrection Bay got lit up on this night, thanks to an impact from a Coronal Mass Ejection (CME) that was hurled from the sun. It was like a birthday cake in the sky with towering candles and when the solar wind blew on it, this radiant wish was granted. This was an extra ordinary experience… extraordinary (!) but I’m not chalking this one up to luck because the writing was on the wall. Two CMEs ejected by the sun and expecting to arrive the night before had me on high alert. This coincided with a beautiful clear patch of Alaskan weather that lasted for the past two nights, thankfully, because the auroras were late! Nothing to do but hope & wait… and shore ‘nuff, they knocked our socks off! Thank you for not being completely predictable, aurora, the surprise factor is worth its weight in gold. More like priceless. One of the more elusive targets I’ve had in my [Aurora Hunting](/aurorahunting-tips.html) career is Seward, Alaska. I have put in my time with numerous attempts at trying to catch a big light show over this location, with minor results, so I am ecstatic that clear Earth weather and active space weather finally came together. ![](/_images/todd/sig.png) Share: ### Photo Info Seward, Alaska Nikon D850 with a 14mm lens 1s, ƒ/2.0, ISO 3200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Sky Blue Pink: Alpenglow at Denali's Reflection Pond | Aurora Hunter [Source](https://www.aurorahunter.com/photos/sky-blue-pink.html) [‹](/photos/seward-candelabra.html) # Sky Blue Pink [›](/photos/spruce-lantern.html) ![](_pix/jaypeg/sky-blue-pink-salat.jpg) --- ## The “Sky Blue Pink” Experience I entered Denali National Park and Preserve at 5:30 pm, photography permit in hand, and drove throughout the beautiful Alaskan mid-August night.

How do you describe what it feels like to gaze upon a star-filled sky? Standing on Earth and looking out into the vastness of space is a feeling - profound, unique, even primal - shared by many since the dawn of humankind. This part of the Milky Way is known as the Cygnus-Orion Arm, one of several arms that comprise the spiral galaxy that we live in. We put names on the features we see to help navigate the starfield. The brightest patch here is called the Cygnus Star Cloud which contains millions of suns, the constellation Cygnus the Swan and the Northern Cross asterism. The long dark shadow in the center is referred to as the Great Rift and is a cosmic dust cloud with particles finer than smoke that obscures the view of even more stars behind it. The dark dusty splotches at top, named the Northern Coalsack and the Funnel Cloud, are dark nebula, a type of interstellar cloud that’s the gravitational spawning ground for stars and planets. The tall tree on the right has a bright star shining like an ornament on its tip. This is Vega, a main sequence star like our Sun, but over twice as big and 40 times brighter. Its relatively close proximity of only 25 light years (150 trillion miles) makes it one of the brightest stars in the sky. When I’m out under the stars, I often ponder and try to grasp the expansiveness of our universe and continually find it absolutely mind-blowing. Ultimately, it’s awe that I feel when staring deep into the nighttime sky and I find this awe inspiring! ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Supernova: Massive Aurora Over the Brooks Range, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/supernova.html) [‹](/photos/star-globe.html) # Supernova [›](/photos/the-legend.html) ![](_pix/jaypeg/supernova-salat.jpg) --- ## The “Supernova” Experience Humongous rippling auroras explode over the top of Alaska’s moonlit Brooks Range on October 15, 2022 near 1:45 am.

Among the giant people was a beautiful young lady named Susitna and a handsome young man who fell deeply in love with each other. Their unbound devotion was so joyous that all the villagers admired them and preparations for marriage were underway. On the day before the wedding a messenger brought dreadful news that a fierce war-like people from the north were invading the country and destroying everything in their path. The village gathered in council to decide what to do. Some suggested going north to attack. The young love-filled man proposed taking gifts to the enemies instead of weapons, showing their interest was in peace and not bloodshed. By morning the brave volunteers were ready to leave. Susitna had tears of sadness when her lover came to say good-bye. He gazed softly into her eyes and whispered, "I shall return soon with news of peace. Meet me by the slender body of water with two arms." With one gentle kiss he turned and joined the departing men. She hurried to the pool of water, known today as the Knik Arm, and began the wait, confident that she would soon be back in her mate's arms. For many days and nights she busied herself while waiting until finally she grew very weary and laid down to rest. She fell into a deep sleep. While she slept, tragic news reached the village that their young men's pleas for peace had been in vain and a terrible battle had broken out. Most of the giant men were killed or captured. When the village women approached the young lady with the dreadful news, they could not bear to disturb her from her peaceful sleep, and left her as she was. To this day Susitna, the sleeping lady, lies there dreaming of the moment her beloved will return to her side and peace once again rules the land. - Legend compiled from the stories of Nancy Lesh and Ann Dixon. - Photo taken on August 17, 2013 at 10 pm from Bootleggers Cove, downtown Anchorage, Alaska. ![](/_images/todd/sig.png) Share: ### Photo Info Bootleggers Cove Nikon D800E with a Nikkor 28-300mm f/3.5-5.6G ED VR lens 1/125 sec, ƒ/10, ISO 800 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Treasure Trove: Full-Sky Aurora Over Seward, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/treasure-trove.html) [‹](/photos/the-legend.html) # Treasure Trove [›](/photos/tree-of-life.html) ![](_pix/jaypeg/treasure-trove-salat.jpg) --- ## The “Treasure Trove” Experience Seward, Alaska is surrounded by a scenic trove of natural beauty during this full-sky aurora display on February 21, 2023 at 1:20 am.

It looked like avalanche country. Ten minutes later I was standing on the continental divide in the Brooks Range of northern Alaska. Gazing north into the moonlit October night my sense of awe grew strong as I took in the entire grandeur of the valley before me. It was a perfect U-shaped valley, carved out by an alpine glacier several millennium before. I slowly descended into it and camped out for a week. Every night I celebrated the moonrise as it illuminated the snow-covered topography, and on some nights the aurora would join the escapade. To me, this was photogenic paradise. On one particular night a rippling arc of aurora broke out overhead as the full moon centered itself in the southern sky.

By the third night of camping my life was cycling with the tides, the moonrise, the stars above and my all-time favorite, the aurora.  Just before midnight on this spectacular night a faint green band developed over the Chugach Mountains as I framed an inviting silhouette deep within some spruce trees.  With very little warning the aurora erupted beyond belief and began dancing up and down the Inlet, curling and whirling on all sides.  I felt enveloped by the forces of nature. Waves of green light streamed beyond my spruce opening and reflected on the ocean below.  I ecstatically used one camera to shoot left, then right, then straight up while using the main camera to continue recording images through the tree branches.  I had the sensation of looking through a window into another world, turbulent yet calming.  My “**Whirled View**.” ![](/_images/todd/sig.png) Share: ### Photo Info Turnagain Arm Nikon D800E with a Nikkor 14mm f/2.8 lens 1.6 seconds, ƒ/2.8, ISO 1600 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # White Satin: Moonlit Aurora Over Portage Lake, Alaska | Aurora Hunter [Source](https://www.aurorahunter.com/photos/white-satin.html) [‹](/photos/whirled-view.html) # White Satin ![](_pix/jaypeg/white-satin-salat.jpg) --- ## The “White Satin” Experience A bright orb of a full moon illuminates satiny white snow blanketing the Kenai Mountains in Southcentral Alaska as multi- colored auroras make music above Portage Lake on November 7, 2017 at 3:33 am. “Cold-hearted orb that rules the night, removes the colors from our sight, red is gray and yellow white, but we decide which is right… and which is an illusion.” These are my all-time favorite lyrics from the classic Moody Blues song, Nights In White Satin. Their CD, Days of Future Passed, went around a few times on this aurora hunt. The music set the mood for an astounding evening filled with spectacular auroras that spread their wings overhead all night long. I couldn’t think of a better place to view such a spectacle than in this moonlit, glacier-sculpted valley. When the stars align and clear earth weather coincides with active space weather everything appears to sing. This night was like living in a dream it felt so perfectly orchestrated and this particular splash of magenta light lasted only a precious few minutes, a brief interlude, but was the highlight of the night due to its rarity. To be fair & honest, the aurora showed up extra bright on this camera exposure but that was enough to help me decide it was right… and not an illusion. “Cold-hearted orb that rules the night, removes the colors from our sight, red is gray and yellow white, but we decide which is right…and which is an illusion.” ![](/_images/todd/sig.png) Share: ### Photo Info Kenai Mountains Nikon D800E with a 14mm lens 2 seconds, ƒ/2.0, ISO 1250 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Aurora Hunter Playing Cards - Alaska Northern Lights Deck [Source](https://www.aurorahunter.com/playing-cards.html) # Aurora Hunter Playing Cards ![](_images/playing-cards/playing-cards-salat.webp) Breathtaking images of Aurora Borealis – the northern lights – adorn this beautiful set of playing cards.

Aurora Hunter [Source](https://www.aurorahunter.com/solar-cycle.html) # Solar Cycle ![](_images/science/salat-solar-cycle-2026-01-sm.webp) The sun has a heartbeat. Every 10 or 12 years it beats, and it beats hard. This is known as the solar cycle and is measured by the number of sunspots visible on the sun. The more sunspots, the more solar flare energy is being released into space which means more aurora activity! ## Q: Where are we now on the solar cycle? According to sunspot numbers, we're currently coasting down from the peak of the Solar Cycle... but history suggests the sun still has the potential to throw some epic aurora parties! The accompanying graph shows how throughout time (horizontal axis) the number of sunspots per month (vertical axis) goes up & down. See the you are here in the lower right? That’s where we are right now on the timeline and the sunspot count is clearly in the Peak Phase. I’ve plotted some of my best aurora photos on this timeline and one thing I’ve learned in the past 30+ years of aurora hunting is there is no time like the present to get out there and get eyes on the sky. ## Recent Solar Cycle & Featured Photos Sun Spots per Month Featured Aurora Photos (click a dot) Advertisement ## Q: When is the best time to see the northern lights? A: Between 11pm and 2am are the peak aurora hours but they can show up anytime from dusk until dawn. Some of the most colorful displays I've ever seen occurred in dawn's early twilight around 5am-7am. ## Q: When should I plan my aurora hunt? Statistically, the equinox months of September and March are the best for aurora activity but the winter months of October-thru-February are also good. In northern latitudes like Fairbanks, Alaska the summer months of May, June & July are too bright to see the aurora. It's challenging to pinpoint the exact timing of a big display. The best advice I can give is to be patient, diligent and pay close attention to the websites that monitor [space weather](links.html) then go for it when the timing seems right. Luck favors the prepared. ## Historical Solar Cycle Sun Spots per Month Data courtesy: SILSO data/image, Royal Observatory of Belgium, Brussels online catalogue of the sunspot index:[https://www.sidc.be/SILSO/home](https://www.sidc.be/SILSO/home), ‘1750-2026’ ![](/_images/science/salat-solar-cycle-2026-01-sm.webp) --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Star Chart - Aurora Hunter [Source](https://www.aurorahunter.com/star-chart.html) # Star Chart for the Northern Hemisphere ![](_images/science/star-chart-black.png) To orient yourself with the stars, face north and rotate the chart until the current season shows at the bottom. The constellations at the bottom of the chart will be in the northern sky, while the stars at the top of the chart will be to the south. This is based on midnight stargazing. As the night progresses, the stars will appear to rotate counter-clockwise due to the rotation of the earth.

These collisions result in countless little bursts of light, called photons, which make up the aurora. Collisions with oxygen produce red and green auroras, while nitrogen produces the pink and purple colors. This reaction encircles the polar regions of the earth and occurs at an altitude of 40-400 miles (65-650 km) in a zone called the “Auroral Oval.” ### When & Where The aurora borealis most commonly occur between 60°-75° latitude, but during great geomagnetic storms the auroral oval expands equatorially and can reach 30° latitude or further. In the northern hemisphere they are called the aurora borealis (northern lights) and in the southern hemisphere aurora australis (southern lights). An auroral display might be observed any night from dusk until dawn as long as it is dark, which excludes Alaskan summer nights (May-July). The best time to view them is between midnight and 2 am. ![](_images/todd/sig.png) [Supernova](photos/supernova.html) --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # License Northern Lights Video Footage - HD & 4K | Aurora Hunter [Source](https://www.aurorahunter.com/aurora-licensing.html) # Northern Lights Video Footage ## Dear Aurora Enthusiast, Welcome to our showcase of dynamic, high-definition northern lights dancing across the Alaskan skies.

The Kp index is a 0-9 scale that measures global geomagnetic activity, based on real-time magnetometer readings and updated every minute by NOAA's Space Weather Prediction Center. Higher numbers mean a stronger geomagnetic storm and a better chance of seeing the aurora at lower latitudes - a Kp of 3 or higher often pushes visible aurora into the northern Lower 48, and a Kp of 6 or higher can bring it as far south as the Midwest. Bz is the north-south direction of the interplanetary magnetic field. A negative (southward) Bz connects more efficiently with Earth's own field and tends to drive stronger aurora, even when Kp hasn't caught up yet.

He received a Bachelor of Science degree in geology at the University of South Dakota in 1986 and a Masters in geology from the University of Wyoming in 1989. With that, he scored a job as an exploration geologist and made that big right-hand turn to Alaska. As a geologist, he enjoyed exploring and unraveling the earth history of the Brooks Range of Alaska and the Andes of Venezuela. However, the seven-year-itch came upon him and he resigned from his corporate day job. The first dream he chased was a year-long walkabout in the "Land Down Under," Australia & New Zealand. Todd returned to Alaska in 1997 to follow through on his dream of becoming a full-time freelance photographer. The next big chapter in life began with a blind date, and in 2001 he married the love-of-his-life, Shay. They reside in Anchorage and enjoy a cabin retreat in Hatcher Pass. With a heated camper on their truck, they eagerly follow their mission statement: ## Be There ~ Preserve the Moment ~ Share It! ![](_images/todd/salat-selfie.jpg) --- ![](_images/home/synergy-salat.jpg) ![](_images/todd/salat-todd-shay-gallery.jpg) --- ## Todd on the Web: [Spaceweather.com ~ August 7, 2026 cover ~ And So It Begins](https://www.spaceweather.com/archive.php?view=1&day=08&month=08&year=2026) [Spaceweather.com ~ March 14, 2026 cover ~ Pi Day Geomagnetic Storm](https://www.spaceweather.com/archive.php?view=1&day=14&month=03&year=2026) [Spaceweather.com ~ September 10, 2025 cover ~ Pipeline Aurora](https://www.spaceweather.com/archive.php?view=1&day=10&month=09&year=2025) [Spaceweather.com ~ March 15, 2025 cover ~ Lunar Eclipse Auroras](https://www.spaceweather.com/archive.php?view=1&day=15&month=03&year=2025) [LiveScience.com ~ December 4, 2024 story ~ Rare Black Anti-Auroras paint letter E](https://www.livescience.com/space/the-sun/extremely-rare-black-anti-auroras-paint-luminous-letter-e-above-alaska) [Spaceweather.com ~ November 27, 2024 cover ~ Black Auroras Over Alaska](https://www.spaceweather.com/archive.php?view=1&day=27&month=11&year=2024) [Spaceweather.com ~ September 18, 2024 cover ~ September Song](https://www.spaceweather.com/archive.php?view=1&day=18&month=09&year=2024) [Spaceweather.com ~ September 2, 2023 cover ~ Mythbuster Auroras](https://www.spaceweather.com/archive.php?view=1&day=02&month=09&year=2023) [Spacweather.com ~ April 15, 2023 cover ~ Blue Spiral over Alaska](https://www.spaceweather.com/archive.php?view=1&day=16&month=04&year=2023) [LiveScience.com ~ April 18, 2022 ~ Iceland Auroras](https://www.livescience.com/auroral-storm-peeks-through-clouds-iceland) [Spaceweather.com ~ April 15, 2022 cover ~ Iceland Auroras](https://www.spaceweather.com/archive.php?view=1&day=15&month=04&year=2022) [Spaceweather.com ~ February 4, 2022 cover ~ Auroras In The Snow](https://www.spaceweather.com/archive.php?view=1&day=06&month=02&year=2022) [Alaska Public Media ~ December 17, 2021 ~ Alaska aurora photographer celebrating 25 years of nocturnal lifestyle](https://alaskapublic.org/2021/12/17/alaska-aurora-photographer-celebrating-25-years-of-nocturnal-lifestyle/) [Spaceweather.com ~ September 2, 2021 cover ~ September Kick-off](https://www.spaceweather.com/archive.php?view=1&day=02&month=09&year=2021) [Spaceweather.com ~ March 22, 2021 cover ~ March Equinox Auroras](https://www.spaceweather.com/archive.php?view=1&day=22&month=03&year=2021) [Spaceweather.com ~ February 23, 2021 cover ~ Auroras From The Window Seat](https://www.spaceweather.com/archive.php?view=1&day=23&month=02&year=2021) [Spaceweather.com ~ February 2, 2021 cover ~ AK Railroad Caboose](https://www.spaceweather.com/archive.php?view=1&day=02&month=02&year=2021) [Spaceweather.com ~ September 29, 2020 cover ~ Auroras At Dawn](https://www.spaceweather.com/archive.php?view=1&day=29&month=09&year=2020) [CNN ~ September 29, 2016 ~ GREAT BIG STORY - Chasing the Northern Lights for a Living](https://www.youtube.com/watch?v=quDJA529PTU) [Spaceweather.com ~ April 30, 2016 cover ~ Springtime Auroras](https://spaceweather.com/archive.php?view=1&day=30&month=04&year=2016) [Spaceweather.com ~ September 20, 2015 cover ~ Sunflower Light Show](https://www.spaceweather.com/archive.php?view=1&day=20&month=09&year=2015) [Atlas Obscura ~ September 8, 2015 ~ The Aurora Hunters Who Spend All Year Chasing the Lights](https://www.atlasobscura.com/articles/the-aurora-hunters-who-spend-all-year-chasing-the-lights) [Indie Alaska, KAKM ~ November 18, 2013 ~ I Am the Aurora Hunter](https://youtu.be/VGgDAaOLiKE) [Alaska Public Media ~ March 11, 2013 ~ Chasing the Elusive Northern Lights](https://alaskapublic.org/2013/03/11/chasing-the-elusive-northern-lights/) [Astronomy Picture of the Day ~ February 12, 2013 ~ Lily Red](https://apod.nasa.gov/apod/ap130212.html)   --- ![](_images/todd/happy-space-todd-salat.jpg) *Todd sending a warm aurora welcome from the Brooks Range!* ![](_images/todd/express-yourself-salat-sm.jpg) *Expressing my jubilant love for the aurora on September 27, 2019 at 10:35 pm.

At midnight, in the pitch dark new moon (i.e. no moon) skies, I got my birthday present ~ a beautiful emerald green aurora. Usually, I like to photograph auroras on moonlit nights so a foreground shows up in the picture, but tonight I knew I'd have to create my own. I searched and searched for a big healthy spruce tree (not always an easy thing to find in the Interior of Alaska, especially at night) and found a big 'ol Christmas tree. I lined it up with the Big Dipper and just as the aurora started to really glow, I locked opened the camera shutter, scrambled and tumbled my way down behind the tree, and back lit it with two “poofs” from my hand-held flash unit. Ta-Dum! That was my contribution to **“Alaska Magic.”** You'll have to ask Mother Nature how she added her secret ingredient. ![](/_images/todd/sig.png) Share: ### Photo Info Murphy Dome, Fairbanks, Alaska Nikon FM with a Nikkor 14mm f/2.8 lens 14 sec w/flash, ƒ/2.8, ISO 400 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Alyeska Aglow | Aurora Hunter [Source](https://www.aurorahunter.com/photos/alyeska-aglow.html) [‹](/photos/alaska-gold.html) # Alyeska Aglow [›](/photos/anchorage-lights.html) ![](_pix/jaypeg/alyeska-aglow-salat.jpg) --- ## The “Alyeska Aglow” Experience The word Alaska is derived from the ancient Aleut word “Alyeska,” meaning the Great Land. The Hotel Alyeska is nestled in the Chugach Mountains of Southcentral Alaska in the resort community of Girdwood, about 35 miles southeast of the city of Anchorage. This eight-story year-round resort has 304 guest rooms and many tourists and locals alike can attest to the rejuvenating qualities of spending the night in this luxurious lodge. The land base for the ski slopes was purchased in 1954 and during the early 1960s the Alyeska Ski Resort was developed. The annual snowfall at the summit of the mountain is 650 inches (54 feet, 16.5 meters). The deep snowpack along with 76 ski runs and 2500 feet of lift-served vertical rise makes this a world-class ski area, not to mention the birds-eye view of glacier-carved valleys and Cook Inlet's Turnagain Arm. It was 3 am on November 16, 2013 when I took this shot of “**Alyeska Aglow**.” It's a 2-second exposure using a wide-angle lens on a 36 megapixel full-frame body and I am astounded at the detail in the buildings. The lodge lighting in the foreground and a nearly full moon high and to the left created a beautiful ambience. The touch of green in the sky is the aurora joining in on the aglow. ![](/_images/todd/sig.png) Share: ### Photo Info Girdwood, Alaska Nikon D800E with a Nikkor 17-35mm f/2.8 lens 2 seconds, ƒ/7.1, ISO 2500 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Anchorage Delight | Aurora Hunter [Source](https://www.aurorahunter.com/photos/anchorage-delight.html) [‹](/photos/alaska-gold.html) # Anchorage Delight [›](/photos/anchorage-lights.html) ![](_pix/jaypeg/anchorage-delight-salat.jpg) Share: ### Photo Info Anchorage, Alaska Nikon D850 with a Nikon 24mm f/1.4 lens 1s, ƒ/2.0, ISO 1600 --- ## The “Anchorage Delight” Experience Bright auroras ripple & swirl over Anchorage, AK at 1:12 am on March 31, 2022 from a vantage point on Point Woronzof.

This stellar view is from Earthquake Park at the western end of Northern Lights Boulevard. ### About the Star… The star you see in this image on the steep slopes of the Chugach Range is at an elevation of 4000 feet above sea level, is 300 feet in diameter (wide as a football field) and is made up of around 350 - 60 watt lightbulbs. From this viewpoint the star is about 15 miles away on land controlled by the Joint Base Elmendorf Richardson and is maintained by military work crews. The original star, put up in 1958 on a guardhouse, was only 15 feet in diameter. In 1959 the Army upscaled it to 117’ in diameter with 250 bulbs. Due to avalanche danger the present configuration was created in 1989 and still requires annual maintenance due to the extreme conditions it has to endure. During the deep winter months military & civilian personnel in the Anchorage & Eagle River area enjoy this beautiful beacon of light. Every year, just after Thanksgiving, the 5-point star gets turned on and remains on until the last Iditarod musher crosses the finish line in Nome sometime in March. ![](/_images/todd/sig.png) Share: ### Photo Info Anchorage, Alaska Nikon D850 with a Nikkor 28-300mm f/3.5-5.6G ED VR lens 1/2 second, ƒ/8, ISO 400 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Blast Off! | Aurora Hunter [Source](https://www.aurorahunter.com/photos/blast-off.html) [‹](/photos/anchorage-supermoon.html) # Blast Off!

The show started with a bang at 8 pm when the energy from a big solar flare blasted earth. It wasn't even dark yet as multi-colored aurora curtains enveloped the deep blue sky and, with only a few small intermissions, the show never let up for the next 10 hours. I danced the moonlit night away surrounded by spectacular 360° mountain and aurora vistas. It was exhilarating. As is often the case, it was near the break of dawn when I witnessed the best display of the night. The moon was going down between the Chugach Range on the left and the Talkeetna Mountains flanking the right when, at 5:20 am on March 7, 2012, it was "Blast Off!" time for the northern lights. The western skies came alive as a curving purple and green curtain climbed rapidly toward the zenith cascading a powerful pattern of light throughout its path. Starry note: This relatively short 2-1/2 second photographic exposure freezes the details of the blast off in motion, including the stars. If you look for the little pinholes of light through the translucent purple curtain, a well-known constellation awaits. Hint: drink deep. ![](/_images/todd/sig.png) Share: ### Photo Info Matanuska Glacier Nikon D700 with a Nikon 14mm lens 2.5 seconds, ƒ/2.8, ISO 800 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Blue Wonder | Aurora Hunter [Source](https://www.aurorahunter.com/photos/blue-wonder.html) [‹](/photos/blood-moon.html) # Blue Wonder [›](/photos/catch-of-the-day.html) ![](_pix/jaypeg/blue-wonder-salat.jpg) --- ## The “Blue Wonder” Experience *You don't go to Denali - Denali comes to you.* Every time I pay a visit to Denali National Park & Preserve I am reminded of this.  Just being there is not enough; you have to be open to it.  With open eyes, heart and soul sooner or later something special falls into your lap (hopefully!).  On this particular July trip it took about two days to get in tune with the natural rhythms.  The first day my brain was busy filtering and filing the previous week's life input.  And then the mountain came out... and my mind went blank.  Sweet! It was late afternoon "magic hour" when I planted myself and three tripods at the north end of Wonder Lake.  Mt. McKinley was teasingly poking its head out of the clouds and around midnight the wind died down (much to my-and the mozzies-relief).  Slowly, as things cooled down, the clouds dissipated.  Magic hour extended for hours into the not-so-dark Alaskan summer night as the sky transformed into a wonderfully rich, deep blue color.  Ambient, indirect sunlight shone on the Alaska Range as snow-clad Denali reflected on the misty surface of Wonder Lake. I had gone to Denali... and **"Blue Wonder"** had come to me. ![](/_images/todd/sig.png) Share: ### Photo Info Wonder Lake, Denali National Park, Alaska Nikon D80 with a Nikkor 18-200mm lens 4 seconds, ƒ/7.1, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Braids of Light | Aurora Hunter [Source](https://www.aurorahunter.com/photos/braids-of-light.html) [‹](/photos/blood-moon.html) # Braids of Light [›](/photos/catch-of-the-day.html) ![](_pix/jaypeg/braids-of-light-salat.jpg) Share: ### Photo Info Brooks Range of Northern Alaska Nikon D800E with a Nikkor 14mm f/2.8 lens 3 seconds, ƒ/3.5, ISO 2500 --- ## The “Braids of Light” Experience Auroras curl their way above the Brooks Range of northern Alaska as a full moon pendant illuminates the fresh snowfield on October 8, 2017 at 1:17 am. Traveling to the Brooks Range is like going to another world, so stark and so raw. I love [aurora hunting](/aurorahunting-tips.html) up here, especially when I need a good dose of solitude. I’m 700 miles away from the creature comforts of my Anchorage home riding out an October snowstorm in my truck camper. The heater is on and my shelter is cozy. Feeling like a modern day caveman, I couldn’t get much more alone. The nearest regular cell phone service is 150 miles north in Prudhoe Bay/Deadhorse and the nearest gas station is in Coldfoot, 80 hard-earned miles south of here. Dodging potholes along the Haul Road/Dalton Highway has been a challenge and now it is reward time. The 36-hour snowstorm is finally over and what was brown tundra a day or two ago is now blanketed in white. As darkness falls the full moon rises illuminating the beautiful winter wonderland before me. An eerie fog bank threatens to cloak everything as it descends into the valley but fortunately I’m able to literally rise above it. I notice a faint green band forming which excites me to no end. This is why I’m here - to hunt auroras. I lock ‘n load two different cameras as the green light moves overhead, shape-shifting into strange & bizarre patterns. I keep shooting hoping that one shot, just one, has that certain special look to it. I think of my wife putting in a request for a tall and narrow photo as the auroras start to stream in rare tight and vertical curls. ”Braids of Light” fall from the stars of Cassiopeia, the Queen’s Chair, and at that moment everything is right in the world. ![](/_images/todd/sig.png) Share: ### Photo Info Brooks Range of Northern Alaska Nikon D800E with a Nikkor 14mm f/2.8 lens 3 seconds, ƒ/3.5, ISO 2500 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Cathedral of Light | Aurora Hunter [Source](https://www.aurorahunter.com/photos/cathedral-of-light.html) [‹](/photos/catch-of-the-day.html) # Cathedral of Light [›](/photos/denali-fireweed.html) ![](_pix/jaypeg/cathedral-of-light-salat.jpg) --- ## The “Cathedral of Light” Experience Enlightening auroras dance above St. Innocent Orthodox Cathedral in Anchorage, Alaska just after 1 am on March 1, 2017. I had been trying to get this shot for 15 years! A week earlier forecasters were predicting clear earth weather & active space weather so I had both eyes on the sky looking for a sign. A little after midnight a faint aurora glow gave me hope. Not feeling the need for speed I had a casual dinner, warmed up the truck, took a last look from our back deck–nothin’ doin’–and was on the road by 12:45 am. Minutes later I ramped onto the Glenn Highway only to glance upward and be awe-stricken to see the auroras had suddenly erupted everywhere! I gave the truck some gas and said to myself, “This show could be over in minutes! Think Todd! Where to shoot in the city?!” It was then the sign came to me and it said.... Turpin Street exit. Of course, St. Innocent Cathedral, go, go, go! I took a hard right onto the exit ramp and had the truck & camper on two wheels (not really, I believe in self preservation) but I knew every second counted so when I pulled into the church’s parking lot I was relieved to see the auroras were still really bouncing. I threw on boots & parka, slapped camera on tripod and plunged into a couple feet of snow. I quickly took a few test shots, not good, re-adjusted focus/settings, post-holed to the right several more yards, planted the ‘pod, took a deep breath, and click. I did a 1/2-second exposure. Bingo! I knew I had it the second I saw it, those rippling pulses of green auroras frozen in motion above the cyan-colored onion domes. This was a spiritual moment.

It was late March and the northland was slowly being liberated from the dark, icy grip of old man winter. On the day before heading homeward I drove beyond the range and onto the North Slope. From this vantage point I could see forever and at 9 o'clock sharp green auroral bands began their dance. I retreated back into what I coined the cusp - where the Brooks Range meets the Slope - and from here I witnessed the apex of a three-week aurora hunt. I saw it developing four hundred miles away on the far northern horizon: the solar wind composing a melody of light as it interacted with gases in our ionosphere. A bright score of illumination began growing, loops uncoiling as bars of light yawned skyward, the tempo gaining momentum. The moonlit mountains and midnight blue sky provided the perfect backdrop. Multiple bands of brilliant teal and pink auroras dazzled my senses as they blazed up and over my head in the shape of a tuning fork, and hit their **"Crescendo"** note. It was music to my eyes. ![](/_images/todd/sig.png) Share: ### Photo Info Brooks Range, Alaska Nikon FM with a Nikkor 14mm f/2.8 lens 10 seconds, ƒ/2.8, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Crown Jewel | Aurora Hunter [Source](https://www.aurorahunter.com/photos/crown-jewel.html) [‹](/photos/catch-of-the-day.html) # Crown Jewel [›](/photos/denali-fireweed.html) ![](_pix/jaypeg/crown-jewel-salat.jpg) Share: --- ## The “Crown Jewel” Experience Snow-capped Denali Mountain, Alaska's crown jewel and tallest peak in North America at 20,310 feet, glows under the radiant brilliance of an exquisite aurora display just after midnight on September 25, 2023. This 4-mile-high mountain looks like it’s touching the northern lights when in actuality it only reaches 1/10th the way up to the 40-mile-high base of the auroras. The illusion is mesmerizing, but that piercing “Highlander” beam of light only appears to emanate straight out of The Mountain as it wraps around the curvature of the earth hundreds of miles beyond the range. This fleeting yet perfect alignment blew me away and was the crowning moment of the night. The deep emerald and ruby red aurora colors reflecting in the braided channels of the Chulitna River below complete this autumn gem. *Starry Note: See the stars of the Big Dipper twinkling behind the sharp center of the curtain?

I was on a serious Auroral hunt and this was the 30th night this winter that I had spent with Denali in my sights. My inverted schedule began like all the rest - I turned the heater back on in my truck camper when I awoke at 7:30pm, did a few stretches to get rid of the camper kinks, cooked up breakfast around 8pm, then took a nice brisk walk. I was in a good space as I focused both my tripod/ camera setups on Denali Mountain, then settled into the front seat of my nice warm truck. The conditions were optimal; crystal clear skies, only 10 degrees below zero, and a near full moon lighting up the snowscape. So far I'd spent most of the nights just stargazing, and for the previous 3 nights the sky has been completely devoid of any Auroral activity. I had decided that maybe I was wanting this shot too much, so I just let it go... "If it happens, it happens" I thought to myself. That night it happened. I have developed a sleep-with-one-eye-open technique for [Aurora hunting](/aurorahunting-tips.html). After sitting in the front of my truck for a couple of hours, that's exactly where I was - Snoozin'! All of a sudden my one alert eye screamed at my other eye to"Wake Up" and when I did I gasped!!! Huge, tall curtains of green and pink light dancing right over Denali!! I flew out of my truck and in one gigantic bound I was at my cameras. I just started clicking different exposures; 2 seconds, 4 seconds, 8 seconds, bracket Todd, bracket! This is supposed to be a relaxing thing, but talk about an adrenaline rush. The curtains were climbing right out of the Alaska Range and performing a mix of tap dance and ballet - it was absolutely extraordinary!! Within 10 minutes the peak moment was over and gracefully the Aurora bowed and faded into the northern sky. I stood there whispering "don't leave....come back..." Oh, so bittersweet. And so it was, the highest mountain on this continent and what I believe to be nature's most magical phenomenon, the Aurora Borealis, getting together for one brief interlude, an exquisite high energy dance - the **"Denali Dance."** ![](/_images/todd/sig.png) Share: ### Photo Info Denali Viewpoint South, Alaska Nikon FM with a Nikkor 35mm f/1.4 lens 4 seconds, ƒ/1.4, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Denali Duo | Aurora Hunter [Source](https://www.aurorahunter.com/photos/denali-duo.html) [‹](/photos/catch-of-the-day.html) # Denali Duo [›](/photos/denali-fireweed.html) ![](_pix/jaypeg/denali-duo-salat.jpg) --- ## The “Denali Duo” Experience The Chulitna River was flowing in mid-October... and so were the auroras.  Perching all night long on top of the new and improved South Denali Viewpoint (near MP 135 on the Parks Highway) is a bit more challenging than in the "olden days" when there was a drive-up overlook.  Today, an even better panoramic view is the reward for those who venture up the quarter-mile hill to take in the grandeur of the Alaska Range. After waiting for about five hours I was busy climbing up and down the hill to generate heat when the auroras decided to warm up the night.  Around 3am a dynamic duo of bright aurora bands electrified the sky above moonlit Mt. McKinley (aka Denali - The High One, The Great One). The northern lights were green in color, the sky a midnight blue but the depth of this night was made for black and white and sepia tones.  The contrasting elements of water, earth, stars and sky complemented each other in shades of boldness. ![](/_images/todd/sig.png) Share: ### Photo Info Mile 135 Parks Highway, Alaska Nikon D80 with a 20mm lens 20 seconds, ƒ/1.8, ISO 0 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Denali North - Color | Aurora Hunter [Source](https://www.aurorahunter.com/photos/denali-north-color.html) [‹](/photos/denali-fireweed.html) # Denali North - Color [›](/photos/denali-spectacle.html) ![](_pix/jaypeg/denali-north-color-salat.jpg) --- ## The “Denali North - Color” Experience I felt fortunate to have drawn a professional photographer's "ProPho" permit for Denali National Park during the solstice week in June.

The initial aurora band streamed across the northern horizon like a meandering green river of light and wasted no time in advancing southward.  Before I knew it the auroras were right on top of me and turning red!  This was not a faint red but a bona fide blood red to the naked eye.  Suddenly, within a matter of just seconds, wings of extra bright northern lights caught sail and wheeled to the sky above, the spruce and birch trees pointing the way amidst the pinpricks of starlight. This astounding view inspired the title "**Epic Flight**," since this display was truly of epic proportions, sending anyone who saw it on a first-class trip to the stars (note the Big Dipper!).  The event was so rare and so beautiful that March 17, 2013 was a lucky St. Patrick's Day, indeed. ![](/_images/todd/sig.png) Share: ### Photo Info Hatcher Pass, Alaska Nikon D700 with a Nikon 17-35mm f/2.8 lens 8 seconds, ƒ/2.8, ISO 2000 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Fire in the Sky | Aurora Hunter [Source](https://www.aurorahunter.com/photos/fire-in-the-sky.html) [‹](/photos/eureka.html) # Fire in the Sky [›](/photos/free-to-fly.html) ![](_pix/jaypeg/fire-in-the-sky-salat.jpg) --- ## The “Fire in the Sky” Experience Brilliant red auroras – clearly & strongly visible to the naked eye – surge over Jordan Pond in Maine’s Acadia National Park on October 10, 2024 at 7 pm Eastern Time. Situated along America’s Eastern Seaboard, this was the beginning of a national event upon which millions of people across all 50 states and Canada got to experience the grandeur of the northern lights. I was near the end of a 12-day leaf-peeping bucket list trip when news of a CME (coronal mass ejection) impacting Earth got the aurora siren sounding. Suddenly, I found myself on the front lines since the East Coast was the first part of the continent to enter nighttime and therefore the first to encounter the aurora-generating effects of this massive geomagnetic storm surge. And WOW, what a surge! It was barely dark when the entire sky exploded with red auroras, perhaps the brightest reds I’d ever seen! I was so excited to do leaf-peeping photography AT NIGHT and to see the orange, yellow & red autumn foliage glowing with warm auroral ambiance. No doubt this was a once-in-a-lifetime experience for me in a very unique setting in Acadia, Maine, over 3300 miles away from my Alaskan home. I have never seen so many people posting colorful aurora photos. Cumulatively, it was perhaps the most hero shots ever taken in North America in one night!

I couldn’t believe my eyes and just started yelling every elated word I could think of! (glad no one recorded that;). Wow, what a great feeling. The meteor seemed to have lasted around 3 seconds, and even popped brightly in the middle as it disintegrated, so I could have just as easily cut off the head or tail of the double-pointed javelin-looking spear of light if the shutter closed prematurely. I have been wishing upon a star for a long time in hopes of catching a fireball and now I know why.

Blooming from bottom-to-top the Common Fireweed is considered a seasonal gauge - when the uppermost blossoms bloom many feel summer is all but over.  During autumn the seedpods burst and, with the help of a fluffy down tail feather, the seeds are distributed by the wind.  They are lofted far and wide looking for targets to take root in and regenerate. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # First Light | Aurora Hunter [Source](https://www.aurorahunter.com/photos/first-light.html) [‹](/photos/eureka.html) # First Light [›](/photos/free-to-fly.html) ![](_pix/jaypeg/first-light-salat.jpg) --- ## The “First Light” Experience I set my alarm for 3:30 am so I'd be fully awake for the 4:30 am sunrise. Not much sleep since just a few short hours ago I experienced a beautiful land-of-the-midnight sunset. But the Mountain was out which was thoroughly invigorating. From a lofty knoll in Talkeetna the **"First Light"** of the day skipped across the clouds, bathing the snow-capped mountains and filling the air with a champagne glow (also known as "sky blue pink"). The vibrant green leaves of the birch and cottonwood trees smelled of a fresh, new summer. Talkeetna, Alaska, with its northwesterly viewing angle, has arguably one of the best skyline panoramas of this fantastic trio of peaks (from left to right): Mt. Foraker (17,400'), Mt. Hunter (14,573'), and the tallest mountain in North America, Denali (20,310'). These geologic marvels give credence to the power of plate tectonics and are the result of an ancient collision zone when "terrain," moving northward on the Pacific plate millions of years ago, was amalgamated to Alaska.

That's what I felt like yelling when this big, emerald green aurora cleared the whitecaps of the moonlit Alaska Range and leapt into the deep blue starry skies above. It wiggled and thrashed about as the aurora performed aerial acrobatics that would have impressed any angler! Finding the fishing hole was a discovery itself. It was March and I was exploring the gravelly Denali Highway east of Cantwell when I came upon a sign: "Winter Road Maintenance Ends Here." Snowmachine and truck traffic had packed the snow fairly well so I locked in the 4WD to avoid fishtailing and kept on going. I found an inviting spot where the trees thinned (didn’t want to get a snag), baited up with my favorite lenses, cast out the tripods and then did what fisherman do, waited patiently… The first couple nights I had several nibbles and one decent bite but none of them were keepas. But on the third night a trophy-sized aurora struck and I set the hook. **Fish On!** I gripped my camera firmly as I opened up the f-stop then lengthened the exposure time to give the aurora some line. Play 'em. Grab the net! My tackle moaned and groaned in the cold weather but held tight and in the end it took three, slightly overlapping, 12-second exposures to get the whole thing into the boat (my first aurora panoramic stitch job). Did I capture it? Nah, the aurora has way too much energy for that action. I like to think in more sporting terms of "preserving the moment."

It was crystal clear and the northern lights were already taking shape so I fueled up my belly with food and went downstairs to tuck my wife into bed. I hadn't set my course for the night so I asked her where she thought I should go. In a sleepy voice she murmured, "Go...to...Lake...Hood...and...get...a...float...plane...shot." Wow, what a great idea! It was going to be an all-nighter on the Hood, the largest seaplane base in the world. Stardate: October 13, 2012. Many of the float planes had already been pulled from the water in preparation for the winter freeze-up but on the east shore (Lake Spenard side) I found this stunning red Cessna 195, a classic built in 1949 and held in high esteem in the aviation community (which is quite large in Alaska). At the stroke of midnight stormy space weather whirled up and sent waves of green auroras reflecting across the serene lake water. Folks behind me had stepped out of the Millennium Alaskan Hotel and, despite the glow of the Anchorage Int'l Airport in the background, we all were treated to a spectacular aurora display. No bright city lights were going to stop this show from going on! Many hours later I tucked my cold toes into bed and, half-awake, Shay whispered, "Did you get the shot?" Yeah, I think so...and then I floated away. *Acknowledgements: I'd like to thank "Captain Kirk," owner of Susitna Energy Systems for the permission to run with this shot.

Some of this solar flare was geoeffective (earth directed) and on March 10, 2011 a gust of solar wind slammed into us. Far below in Alaska I witnessed the dynamic interplay of forces from a windy Pt. Woronzof bluff near the Anchorage International Airport. I had broken a dinner date with my wife because online the scientific websites that monitor real-time magnetic disturbances and solar wind speed were bouncing like crazy. The Kp index, a 1-to-10 number summarizing geomagnetic activity, was in the red! I clocked on at 8 pm and was scanning the sunset when a faint aurora flicker caught my eye over Pt. McKenzie to the northwest. It was not even dark yet! I quickly got my tripods set up and by 8:30 pm the auroras were dancing over Mt. Susitna, the Sleeping Lady. I had been envisioning this shot for two decades. A half moon illuminated the snow on the Lady while the twilight of a distant sunset burnt in a deep orange glow. The northern lights were a lively shade of green that stretched into tall, barely detectable, rays of magenta. Ice pans made a grinding sound as they slowly rode the incoming tide into the Cook Inlet. From water-to-sky everything was in constant movement including the numerous flights arriving and departing the airport. Talk about a state of "**Flow**." When I thought it could not get any better it did; my wife showed up out at the Point with a warm take-out dinner…. the night had become a dream date! ![](/_images/todd/sig.png) Share: ### Photo Info Anchorage, AK Nikon D700 with a Nikon 28mm f/1.4D lens 2.5 seconds, ƒ/1.6, ISO 800 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Freebird | Aurora Hunter [Source](https://www.aurorahunter.com/photos/freebird.html) [‹](/photos/free-to-fly.html) # Freebird [›](/photos/go-deep.html) ![](_pix/jaypeg/freebird-salat.jpg) Share: ### Photo Info Hatcher Pass, Alaska Nikon FM with a Nikkor 16mm f/2.8 fisheye lens 10 sec, ƒ/2.8, ISO 200 --- ## The “Freebird” Experience Many moons ago (a decade-plus) I searched long and hard for a piece of land in Alaska that would take me to where my dreams were free to roam. Eventually I found an old half-built cabin up in Hatcher Pass. It was eighty miles north of Anchorage ~ an adequate getaway distance ~ and the main beam of the cabin was aligned with the North Star. Perfect! With the help of my dad and some friends we transformed the framed-out octagonal structure into an aurora viewer's delight. It was here that I cut my teeth on aurora photography. Today, I continue to find peace, tranquility, and dream-space, at the Hatcher Pass cabin. The inspirational feelings it helps generate has earned the cabin it's nickname, **"Freebird." ** On this particular evening a green glow in the northern sky sent my spirits soaring as the hope for good things grew. I prepared the cabin with the warm incandescence of candles then lugged my gear through the snow and set-up below. Fingers of the aurora began to lick southward across the sky. The northern lights grew in size until the entire sky radiated with a force that never fails to leave me awe-struck. The "corora effect" created an umbrella of light as red and green rays rained down on all sides of me. Facing southward, I pointed my widest-angle lens nearly straight up into the sky to record as much as possible. I was very pleased the Big Dipper had rolled in for the show and spilling out of the Dipper stood the North Star. The moonlit snow with a single moose track carved through it and the tall spruce trees provided the framing. I felt the connection being made and as a rush of that**"Freebird"**feeling coursed through my veins. ![](/_images/todd/sig.png) Share: ### Photo Info Hatcher Pass, Alaska Nikon FM with a Nikkor 16mm f/2.8 fisheye lens 10 sec, ƒ/2.8, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Galaxias | Aurora Hunter [Source](https://www.aurorahunter.com/photos/galaxias.html) [‹](/photos/free-to-fly.html) # Galaxias [›](/photos/go-deep.html) ![](_pix/jaypeg/galaxias-salat.jpg) --- ## The “Galaxias” Experience Stargazers, this is the view looking north-northwest on January 9, 2010 at 1:23 am from Hatcher Pass, Alaska. Between the spruce goalposts is the skyline of Mts. Foraker, Hunter & Denali 100 miles away and four miles high. The auroras are over 300 miles away and 40 miles high. Many light years above that is a "milky" swath of light made up of billions of stars and planets that are all part of our spiral-shaped home galaxy, the Milky Way. **Galaxias** literally means milky in Greek. This 30-second exposure reveals more than the human eye can see which lends to a profound sense of scale. Woodcutters, I had to take down 28 spruce trees to open up this view of Denali from our Hatcher Pass cabin. That warmed me up several times. Once, while cutting and hauling the logs up the hill. Then, splitting them with a hefty wood maul/axe is always a good workout. And finally, after a good year or two of drying time the final warmth comes while burning them in my wood stove during the wintertime. For instance, when I took this shot in January it was 20 below but the cabin was cozy warm. ![](/_images/todd/sig.png) Share: ### Photo Info Hatchers Pass Nikon D700 with a Nikkor 17-35mm f/2.8 lens 30 seconds, ƒ/2.8, ISO 1600 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Guiding Light | Aurora Hunter [Source](https://www.aurorahunter.com/photos/guiding-light.html) [‹](/photos/goddess-of-dawn.html) # Guiding Light [›](/photos/heart-of-alaska.html) ![](_pix/jaypeg/guiding-light-salat.jpg) Share: ### Photo Info Godafoss Falls, Iceland Nikon D850 with a 14mm lens 1s, ƒ/2.0, ISO 2000 --- ## The “Guiding Light” Experience Delicate yet powerful aurora rays boldly shoot the gap between clouds over Godafoss Falls in northern Iceland on April 14, 2022 at 11:47 pm. The bright, nearly full moon was backlighting the clouds and competing for light space here, but these auroras would not be denied! Leading up to this moment, a strong wind was blowing waterfall mist everywhere while I strolled up the trail to the falls. As I got closer, I did a test shot and thought wow, look at those cool wings of clouds… and is that an aurora glow in-between? I picked up my pace, and when I saw a spike develop, I broke into an all-out sprint until my lungs burned to get in position for this composition.

For three days my wife & I tagged along on a moose hunt with our "mountain buddies" and ate fresh moose back-straps around a campfire while watching the northern lights dance across the autumn skies. Delicious memories but when the Harvest Moon started coming up it was time to get serious about our hunt…cameras locked and loaded. The skies were clear and I was in hot pursuit of a reflection shot in Lake Louise country (west of Glennallen). Every waterhole was a potential target, wind willing, and a northerly viewing angle was essential. I set my sights on Elbow Lake and the dry shoreline grass glowing in the full moonlight pulled me in deeper. Sowing the seeds of the soul–harvest time! The water was like glass on the first night but in ten hours only one minor aurora blip was spotted. The wind whipped up on the second night, which pretty much ruins the reflection concept (admittingly a bit disappointing), so I took a deep breath and remembered my friend's favorite saying, "It's all about the hunt." Patience. At 12:30am inspiration came a knocking as a green band developed to the northeast so I ran to my spot and started shooting–open fire! For the next hour and a half the aurora danced and swirled to its own beat. Waves of energy would come and go, as did the wind. But during one critical juncture the lake was calm enough to reflect the aurora as it curled and intensely wrapped around itself. This was the moment when "**Harvest Hunt**" was added to the game bag. ![](/_images/todd/sig.png) Share: ### Photo Info Lake Louise Nikon D700 with a Nikon 17-35mm f/2.8 lens 4 seconds, ƒ/2.8, ISO 800 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # I Breathe Aurora | Aurora Hunter [Source](https://www.aurorahunter.com/photos/i-breathe-aurora.html) [‹](/photos/heaven-and-earth.html) # I Breathe Aurora [›](/photos/icelandic-flow.html) ![](_pix/jaypeg/i-breathe-aurora-salat.jpg) --- ## The “I Breathe Aurora” Experience I was on a March aurora hunt in the Interior of Alaska. The near full moon illuminated the snowy hills around Chena as I gingerly slipped into the rejuvenating hot springs and immersed my chilled body. Steam rose and my hair froze as I became warm to the bone (a very welcome relief after truck camping for a week without a shower!). Thank you geothermal energy. Afterward, feeling entirely refreshed, I donned my parka, grabbed my camera and took a deep breath as I rejoined the clear winter night. As if on cue aurora streamers rose from the horizon and began to dance the night away, increasing with tempo as the midnight hour came and went. I began by shooting in my typical lone-wolf mode but on this moonlit evening I was soon howling with a large, multinational pack of fellow aurora enthusiasts. Around 1 am on March 22, 2016 the lights erupted in a crescendo of high-speed brilliance and a hundred spellbound auroras watchers around me harmonized with synchronized cries of delight! Inspired by the collective high pitch notes I let out my best "Owwwuu." It was vividly clear that watching the auroras transcended cultural boundaries and I caught myself smiling as I composed a shot under this cool dragon sculpture that looked like it was exclaiming **"I Breathe Aurora!"** ![](/_images/todd/sig.png) Share: ### Photo Info Chena Hot Springs, AK Sony a7S-II with a Nikkor 14mm f/2.8 lens 1/25 sec, ƒ/2.8, ISO 40000 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Kaleidoscope | Aurora Hunter [Source](https://www.aurorahunter.com/photos/kaleidoscope.html) [‹](/photos/icelandic-flow.html) # Kaleidoscope [›](/photos/kennecott-treasures.html) ![](_pix/jaypeg/kaleidoscope-salat.jpg) Share: ### Photo Info Flattop Mountain, Anchorage, Alaska Nikon FM with a Nikkor 14mm f/2.8 lens 10 seconds, ƒ/2.8, ISO 200 --- ## The “Kaleidoscope” Experience In Greek, **"Kaleidoscope"** means kalos (beautiful) + eidos (form) + scopos (watcher), the beautiful form watcher. Near dawn on Wednesday morning, October 29, 2003, I felt like I was transported into a kaleidoscope. I was lying in the moonless dark hillside above Anchorage, looking east into Powerline Pass from the Flattop overlook, while my mind and spirit were racing far above catching a ride on the endless variety of colors and forms that the aurora borealis offered. These were some of the brightest and varied colors I'd ever seen and preserved on film. Skygazers around the world were tuned into the show that commenced locally around 8:30 pm on Tuesday night, October 28, 2003 with some active green and deep red auroras. A day earlier, the sun had announced its intentions with a dramatic full-halo coronal mass ejection, the one scientists reported sent billions of tons of charged particles into space. The solar wind streamed towards us at over a million miles per hour, yet when it arrived at earth and started to squeeze our magnetic shield the sudden increase in pressure was softer than a baby's breath. But that's all that's needed to pump energy into our ionosphere and to generate "the lights." ### Kaleidoscope of Colors The rare deep purple corona near the top of this photograph is at an elevation of 300 miles (+/-) and owes its existence to resonance scattering. This miraculous two-step process first involves ionizing nitrogen molecules with the incoming solar particles, then lighting them up with the dawn's early high-altitude sunlight. The charged nitrogen absorbs the sunlight and re-emits the energy in the breath-taking bluish-purple hues. Streaming below this at an elevation of 100-300 miles is a brilliant pink curtain. The pink is a mixture of red oxygen atom emissions along with the nitrogen purples. Zipping about 50-100 miles above our heads from O'Malley Peak to Flattop was a ribbon of green. Green comes from excited oxygen molecules releasing their unwanted energy at a wavelength of 5577 angstroms, which happens to coincide with the peak of the human eye's sensitivity. It's all pure au naturel.

From Tok through Chicken, AK we entered the Top of the World Highway, hit Dawson City, Canada then dropped down to Whitehorse. It was a great week of road-trippin’ through autumn colors but we had yet to even see our first star due to the rainy, overcast conditions. We were on our way back up the Alaska “Alcan” Highway when the clouds began to part. We set up camp along Kluane Lake northwest of Haines Junction and started cooking dinner while the night seeped in… and the stars entered stage left one by one; the opening act. Moonlight illuminated the snow-capped Ruby Range in the distance but the real star of the show was the aurora. With a brilliant burst of energy she exploded onto the scene wearing a veil of multi-colored sheer draperies of light flowing across the sky and dancing on the water. It was by far the highlight of the trip deserving a standing ovation after a spectacular performance. Much to our delight the aurora returned for a curtain call then bowed and faded gracefully into the night.

With the longer days of an Alaskan summer right around the corner the April sky was losing its darkness and amidst the twilight blue background the aurora skipped across the frozen South Fork Koyukuk River. Ice & snow, spruce & flow, stars & aurora, what a show!

At 4396 feet tall, this landform was overridden and sculpted by glaciers over ten thousand years ago as they traveled down the Susitna Valley (from right to left in this photo).  Somewhat isolated from the rest of the Alaska Range the Lady is a remnant from the erosive power of the Ice Age.   Legend has it the mountain is a giant, a maiden who fell asleep while waiting for her lover to return from battle ### ~ The Legend ~ *(compiled from the stories of Nancy Lesh and Ann Dixon)* Many millennia ago, a clan of gentle giants inhabited the Great Land, now known as Alaska.  Among the giant people was a beautiful young lady and a handsome young man who fell deeply in love with each other.  Their unbound devotion was so joyous that all the villagers admired them and preparations for marriage were underway. On the day before the wedding a messenger brought dreadful news that a fierce war-like people from the north were invading the country and destroying everything in their path.  The village gathered in council to decide what to do.

The young woman hurried to the pool of water, known today as the Knik Arm, and began the wait, confident that she would soon be back in her mate's arms.  For many days and nights she busied herself while waiting until finally she grew very weary and laid down to rest. She fell into a deep sleep. While she slept, tragic news reached the village that their young men's pleas for peace had been in vain and a terrible battle had broken out.  Most of the giant men were killed or captured.  When the village women approached the young lady with the tragic news, they could not bear to disturb her from her peaceful sleep, and left her as she was.  To this day, the sleeping lady lies there dreaming of the moment her beloved will return to her side and peace once again rules the land. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Legendary Lady | Aurora Hunter [Source](https://www.aurorahunter.com/photos/legendary-lady.html) [‹](/photos/kiss-the-sky.html) # Legendary Lady [›](/photos/memorial-lights.html) ![](_pix/jaypeg/legendary-lady-salat.jpg) Share: ### Photo Info Earthquake Park, Anchorage, Alaska Nikon FM with a Nikkor 35mm f/1.4 lens 4 seconds, ƒ/1.4, ISO 200 --- ## The “Legendary Lady” Experience This shot was taken in Anchorage looking west from the Earthquake Park overlook around 1am on September 30, 2000.

We headed northeast up the Glenn Highway, took a left at the Lake Louise junction, then bounced down a pothole-filled side road. We popped up the truck camper along one of my favorite ponds that dot the region and stepped out into crisp, clear and calm conditions. Stardate: September 13, 2012. The smell of fall was in the air and, as my eyes adjusted to the darkness, an aurora glow became apparent on the far northern horizon. Time to go to work, although it felt more like play. The Milky Way galaxy stretched upward against the deep black new moon (ie, no moon) skies while the bright pinpoint of Jupiter shone like a beacon in the V-shaped pattern of Taurus the Bull (just above the clouds). Further above, the tight but bright Seven Sisters of the Pleiades open cluster twinkled prominently. I set the exposure time for 20-seconds to burn in the starfield and, lo and behold, a red glow appeared. I have seen the coveted red northern lights this bright to the naked eye in the past but they are very rare. In this case, the camera gets much credit for acting like night-vision goggles and revealing what the less sensitive human eye has a harder time detecting. To complete this composition, while the camera shutter was still locked open, I used my little headlamp to paint the lily pads with a beam of light. "**Lily Red**" set the mood for a great trip. ![](/_images/todd/sig.png) Share: ### Photo Info Lake Louise, Alaska 20 sec, ƒ/2.8, ISO 4000 ### Lily Red on the web [Astronomy Picture of the Day ~ February 12, 2013 ~ Lily Red](https://apod.nasa.gov/apod/ap130212.html) --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Lunar Eclipse 12-20-10 | Aurora Hunter [Source](https://www.aurorahunter.com/photos/lunar-eclipse-2010.html) [‹](/photos/kiss-the-sky.html) # Lunar Eclipse 12-20-10 [›](/photos/memorial-lights.html) ![](_pix/jaypeg/lunar-eclipse-2010-salat.jpg) --- ## The “Lunar Eclipse 12-20-10” Experience North America was a great place to be for the total "Lunar Eclipse 2010" (see map below). In Alaska, the lunar eclipse began on December 20, 2010 at 9:33 pm AST (Alaska Standard Time) and it looked like a bite had been taken out of the moon (photo 1). The bite size grew (photo 2) and by 10:41 pm AST totality commenced (photo 3) and lasted for 72 minutes. In eastern (EST) and central (CST) time this occurred on the winter solstice, 12/21/10, but with the Alaska time change (4 hours behind EST) the lunar eclipse fell primarily on 12/20/10. Why is the moon orange during a lunar eclipse? Imagine yourself standing on the bright white full moon (you'll need sunglasses at first). When the sun aligns itself directly behind our planet and the earth's shadow falls on the moon you are now standing in the lunar eclipse (shades come off). The earth blocks direct sunlight from reaching you but a brilliant fiery orange ring of light surrounds the circumference of the earth as sunlight filters through our atmosphere. This is every sunrise and sunset around the world seen at once. A stunning view from your lunar vantage point! This copper red glow reaches the moon and casts an eerie amber mood light on the lunar surface all around you. Ecliptic twilight. Personal experience: I raced out to the Anchorage Int'l Airport to pick up my parents who were visiting for the holidays. Their flight arrived at 9:30 pm, coincidently just as the eclipse started so we quickly drove to the nearby Earthquake Park and joined in a lunar party that was already underway.

I’ve noticed for many years that by just being in the presence of this mountain I absorb an energy of some sort that I’m calling “Mountain Mojo.” ### Mountain Tidbits - A 2015 US Geological Survey measured the height of Denali at 20,310 feet (6,190 m). That’s 10 feet shorter than the 1950s calculation of 20,320’. Did it shrink? Geologists say no, they just have more accurate GPS technology these days and the mountain is actually still rising, slowly but surely. How do you spell relief? D-E-N-A-L-I - On a global scale, Denali’s elevation does not compete with a lot of mountains found in the Himalayas & Andes. But when it comes to RELIEF—the height above the ground level of the area—it is #1 in the world measuring 18,000 feet from the base of the mountain to the peak. That’s granite for ya, a very tough rock with a high quartz content. - The world’s tallest mountain is Mt. Everest at 29,029 feet above sea level (8,848 m) but its actual base-to-summit relief is only 12,000 feet, quite a bit less than Denali. - When a mountain’s relief includes what goes on below sea level then Mauna Kea on the island of Hawai’i holds the world record at 33,476 feet from ocean floor-to-summit. ![](/_images/todd/sig.png) Share: ### Photo Info Byers Lake, South-central Alaska Sony a7R-II with a Sony 24-240mm lens 1/1000 second, ƒ/10, ISO 100 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Mystic Mascot | Aurora Hunter [Source](https://www.aurorahunter.com/photos/mystic-mascot.html) [‹](/photos/mysterious-moment.html) # Mystic Mascot [›](/photos/ninilchik-spires.html) ![](_pix/jaypeg/mystic-mascot-salat.jpg) --- ## The “Mystic Mascot” Experience Powerful auroras double the viewing pleasure by reflecting on Olnes Pond, north of Fairbanks & Fox, Alaska, on October 11, 2017 at 8:38 pm.

I was in the Alaska Range on the Parks Highway and in just a few days it would be May. The geese were flying north again, and the window of darkness had narrowed down to a precious three hours, midnight-to-3am. This was the last aurora hunt of the season. I was delighted to discover that a thaw-freeze cycle had turned the top crust of the deep snow into concrete. I could walk, jog or ski anywhere in a heartbeat so I played a lot. On night #4 I had my two camera/tripod set-ups located on opposite sides of the knoll when I saw an ominous glow suddenly appear to the east. I then realized I wanted the lens on the other camera! I sprinted across the snowfield and did a third base slide at my secondary camera, grabbed my lens of choice and bolted back to primo spot #1. An onlooking spruce tree cast a moon shadow as the smoky curls of the aurora doubled in size. The display was awesome, yet short-lived, but I knew these memories would get me through the long summer months ahead. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Peak Moment | Aurora Hunter [Source](https://www.aurorahunter.com/photos/peak-moment.html) [‹](/photos/patriot-bear.html) # Peak Moment [›](/photos/perfect-storm.html) ![](_pix/jaypeg/peak-moment-salat.jpg) --- ## The “Peak Moment” Experience In March 2010 I embarked on a 2-1/2 week lone wolf aurora hunt up the Dalton Highway (Haul Rd) to the Brooks Range of northern Alaska. Despite being in the low of the 11-year solar cycle I saw [aurora activity](/solar-cycle.html) 13 of the nights and was fortunate to score mostly clear skies. Near the end of the trip the weather turned bad and I was blown off of 4600' Atigun Pass by a wicked wind that had knocked over both my tripod/camera set-ups the night before (nothing a little duct tape couldn't fix). How do you spell relief? V-V-Vrrroom–that's the sound of my cold truck starting and dutifully transporting me down the south side of the range to a relatively calm spot, one with a view… The streaming veil of clouds had a calming effect (since I was no longer in them) as they sailed over the edgy, pyramid-shaped Dillon Mountain. Moonlight exposed the sharp boundary where the tree line, which has gained a tentative foothold in the avalanche zone, terminates abruptly against the rugged limestone face of the mountain. Anticipation grew as stars began to twinkle through the thinning clouds and at the stroke of a quarter 'till midnight on March 27, 2010 the auroras sparked, making my day! The alignment was wonderfully fortuitous as a column of light emerged from right over the peak of the mountain and proceeded to erupt into a tight but intense geomagnetic substorm; the break-up. Green auroras flared with pink and white, illuminating this "**Peak Moment**" with colorful radiance. The nighttime world was everything but cold, dark and windy. For a long moment it was euphoria. ![](/_images/todd/sig.png) Share: ### Photo Info Brooks Range, Alaska Nikon D700 with a Nikon 17-35mm f/2.8 lens 2.5 seconds, ƒ/2.8, ISO 800 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # The Phoenix | Aurora Hunter [Source](https://www.aurorahunter.com/photos/phoenix.html) [‹](/photos/perfect-storm.html) # The Phoenix [›](/photos/pilots-dream.html) ![](_pix/jaypeg/phoenix-salat.jpg) --- ## The “The Phoenix” Experience It was hailed as the best aurora show in a decade.  The sun unleashed a massive solar flare in early November 1998, and the resultant geomagnetic storm lasted 2-1/2 nights.  Outlandish auroras graced the skies across Alaska, Canada, and the northern Lower 48.  It was the big one!

A big gust of solar wind was predicted to impact earth at any moment and if a geomagnetic storm kicked in I knew exactly where I wanted to be ~ at the tip of Turnagain Arm with the AWCC in my sights. It was low tide and the mouth of the river reflected the Chugach Mountains beautifully. Quite suddenly pink auroras bridged the Twentymile Glacier Valley and two brilliant bands of light turned to four with the help of the reflection.

With such poor visibility I went online to the various space weather websites and discovered that a high-speed solar wind stream was buffeting Earth, which is awesome news to an aurora hunter. I then discovered that the folks up north in Fairbanks were getting lit up with heroic coronas straight overhead and it wasn't even 9 pm yet! And here we were socked in. I figured my only hope was to gain elevation and rise above the fog so I raced to the Flattop trailhead along Anchorage's upper hillside, scrambled into position and preserved this jubilating moment at 11:17 pm. This image is actually composed of four overlapping 8-second exposures stitched together to showcase the wonderful 180° panoramic viewpoint. The bright glow to the left is from the Anchorage city lights coupled with a rare treat of red auroras dancing over Wolverine Peak. The tallest pointed mountain near the center is O'Malley Peak while the dark swath of spruce trees below and climbing to the right is Powerline Pass. At the far right edge is Flattop Mountain.

The predominately gravel highway sidles along the southern flank of the Alaska Range making it a great place to get lost without ever really losing your way. On this particular evening, we parked the truck camper next to a small lake in the Tangle Lakes region west of Paxson and spent most of the night just stargazing... hoping the auroras would join in on the fun. Around 4 am, I was considering turning in for the night but I've learned this lesson before and decided I better not waste the dawn. An hour later, in the last remaining moments of nighttime, a delicate tapestry of purple auroras appeared backlit as they shimmered against dawn's early light, making the wait that much more rewarding. The stars and the northern lights twinkled on the reflective surface of the lake until it was too bright to see them. Daytime had arrived, which meant time to go to bed. ### Science note: *The rare purple aurora occurs at an altitude of 300 miles (+/-) and owes its existence to resonance scattering. This miraculous two-step process first involves ionizing nitrogen molecules with the incoming charged particles, then lighting them up with the dawn's early high-altitude sunlight. The charged nitrogen absorbs the sunlight and re-emits the energy as purple light.

Just a handful of minutes earlier I had been driving north up the Parks Highway when I glanced to the right and was stunned to see a huge bank of auroras coming in hot from the east. I quickly pulled into a roadside parking lot then, moving as fast as humanly possible, I grabbed my camera & tripod and scooted down a snow machine trail. I came upon this wood-framed window of opportunity, took a deep breath, and composed the shot.

This whole night was phenomenal and somehow unlike any aurora experience I’ve ever had. I suppose that’s why I love doing this so much, every show is different. The auroras kicked in just after 8 pm, which was remarkably early and the result of a fresh impact from a CME (Coronal Mass Ejection) emitted from the sun. I photographed on & off for hours as the northern lights battled the clouds for dominance of the skyway. At around 2:30 am, I was in my camper eating lunch when I noticed the clouds were rapidly parting and that I had better get a move on it! By now I ‘d discovered my favorite foreground which centered on a little gap in the spruce trees that felt like a gateway to something special. As the auroras amped up into some very exciting shape-shifting maneuvers I was delighted to see that my 3-second camera exposures were revealing rose-colored tints. I shot like crazy during this 20-minute window while trying to preserve the jaw-dropping sights I was experiencing. Amidst some wonderfully bizarre & wild looking imagery, this shot rose above the others and looked like an Angel, a Phoenix, or perhaps Pegasus the winged horse. I love the delicate yet strong wings fanning outward from the zenith overhead, and the tall spruce trees appear to be pointing at this amazing display of power. Two open clusters grace the starfield - the Hyades & Pleiades - the birthplace of stars. Is it me, or do those clouds resemble a cute baby chick (or quail) scurrying along? This image speaks to me, and these are my impressions. No two people see the exact same thing in an aurora image, so let your imagination run free. ![](/_images/todd/sig.png) Share: ### Photo Info Cantwell, Alaska Nikon D850 with a 14mm lens 3s, ƒ/2.0, ISO 3200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Skybow (color) | Aurora Hunter [Source](https://www.aurorahunter.com/photos/skybow.html) [‹](/photos/sky-blue-pink.html) # Skybow (color) [›](/photos/spruce-lantern.html) ![](_pix/jaypeg/skybow-salat.jpg) --- ## The “Skybow (color)” Experience A huge rainbow-shaped aurora band stretches far above the Alaska Range near 2 am on April 8, 2024 as brilliant rays of northern lights rain down upon Denali Mountain, the tallest peak in North America at 20,320' high.

On a recent photo trip into Denali National Park & Preserve I was, once again, reminded of the above mantra. Just being there is not enough; it's a process of attitude adjustment. With open eyes, heart and soul sooner or later something special falls into your lap (hopefully!). It was solstice week, the longest days of the year, and I was driving about 7 mph over Polychrome Pass just winding down the park road hoping something would come to me. I rounded a bend and loping straight up the middle of the road toward me was solo lobo, a lone wolf (spanglish translation). When he saw me he flushed into the heavy brush, disappearing from sight. I turned my rig around on the narrow road and drove a 1/2-mile while trying to predict where the wolf might re-emerge. At an inviting clearing I parked and waited with open windows. Here he comes again (I almost cried wolf!). This time he was more tolerant, making a small, cautious detour around me while passing through a colorful patch of bluebell wildflowers. He paused for a second to check me out and my heart froze as his gaze from those golden orbs bore straight into me. I clicked the shutter and he ambled on leaving me with an exhilaratingly long lasting sensation that I had looked right into the "**Soul o' Lobo**."

This extreme destination above the Arctic Circle always brings with it a more experiential journey, and on March 25, 2019 around 3 am the experience was elevated to the spiritual level. It was Night #10 of the aurora hunt and the sky was 100% cloud-covered. There was NO hope at all for seeing the aurora in these overcast conditions so I was reading a good book to help me get through the down time. Every once in a while, I’d step out of the truck camper to scan the sky and howl back to a lone wolf that was keeping me company. Then I saw it; one star. Just one flickering pinpoint, but that was all it took to turn my senses full on. Before long I saw three stars, no wait, six, then a dozen and I could tell the small patch of clear sky was growing in my direction, and so were my hopes! With clouds constantly threatening from all sides, the heavens slowly opened up above me with star-filled clarity. I was positioned in front of the jagged peaks flanking Atigun Gorge when it happened. Rising above the mountains thee most amazingly graceful auroras spread their radiant wings and soared on their journey around our planet. If auroras could sing it would have been the sound of angels in glorious harmony. It was so beautiful! For two hours, from horizon-to-horizon, the northern lights took flight into the night and left me light-hearted. The flow of this mesmerizing beauty made me feel blessed in its wake which was more than I ever hoped for. ![](/_images/todd/sig.png) Share: ### Photo Info Atigun Gorge, Brooks Range, AK Nikon D850 with a 14mm lens 2.5 sec, ƒ/2.0, ISO 3200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Spring Rays | Aurora Hunter [Source](https://www.aurorahunter.com/photos/spring-rays.html) [‹](/photos/sky-blue-pink.html) # Spring Rays [›](/photos/spruce-lantern.html) ![](_pix/jaypeg/spring-rays-salat.jpg) --- ## The “Spring Rays” Experience My world revolved within four hours, midnight-to-4am, the fading window of darkness on April 20, 2013. I was in the Alaska Range on a springtime aurora hunt, my last before the long days of summer put the aurora to bed for the season. The clarity of this night, with a half-moon illuminating the snow, made me feel like I could reach out and touch these classic peaks (from left-to-right); Mts. Foraker, Hunter and McKinley, more affectionately known as Denali. At 1:30 am a faint green band developed and hovered quietly for an hour, giving me hope. Suddenly, right when I was thinking a big aurora might not happen, it activated! The green band began to ripple and then folded onto itself as it divided into multiple columns of light. They swelled upward into translucent curtains tinged with deep purple. This was the hero nature moment I'd been waiting for as "**Spring Rays**" filled the sky over Denali! The moment lasted for a good half-hour but all too soon the aurora began to subside. The short night faded into the early dawn as I plopped on my back in the snow to absorb the raw beauty and thanked my lucky stars for the wondrous injection of energy. Star Stories: The pentagon-shaped constellation on the left is Auriga, the Charioteer, and was named a couple thousand years ago to honor the importance of chariot drivers in those societies. Perseus is the group of stars in the upper right and includes the head of Medusa (represented by a eerily winking variable star). Further to the right is part of the constellation Andromeda, the beautiful maiden that Perseus rescued from a sea monster in ancient Greek mythology. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Stormy Night | Aurora Hunter [Source](https://www.aurorahunter.com/photos/stormy-night.html) [‹](/photos/star-globe.html) # Stormy Night [›](/photos/supernova.html) ![](_pix/jaypeg/stormy-night-salat.jpg) --- ## The “Stormy Night” Experience A massive aurora storm front moves westward engulfing the sky over Mount Denali in the Alaska Range on March 19, 2021 at 11:24 pm, the eve of the spring equinox, while curiously leaving a clear patch around the moon and the Pleiades star cluster. This was Night #1 of a 10-night & 1000-mile aurora hunt. The entire trip was blissful, but when it comes to aurora happenings that I witnessed, nothing compared to this very first evening of my journey when an aurora show of epic proportions stormed the night!

My job: to get the aurora juices flowing with a PowerPoint presentation of my northern lights photography followed by some hands on camera instruction. A few months beforehand I had been asked to present to 28 travelers who were signed up for a combo trip to watch the Iditarod sled dog race and hopefully to the catch the auroras. I was delighted when I found out it was going to be at this beautifully located lodge with its panoramic view. The presentation went well and afterward we pulled out the smartphones to see how the [aurora forecast](/northern-lights-prediction.html) was looking....quiet to unsettled. That's like a weatherman saying it's going to be somewhere between cloudy and clear. In other words, not quite sure, so the only thing to do is stay up late and watch the skies. Just after midnight on March 6, 2016 a green glow began to develop over the Alaska Range to the northwest as the auroras slowly started to dance. Game on! For several hours mellow light waves ebbed and flowed. Then, at a little after 4 am, a faint deep dark red tint became noticeable which was exposing beautifully with an 8-second long camera exposure. Myself and a few other hearty late-nighters were extremely excited to be getting red auroras in our photos! Especially when they occur right over this classic Alaska Range profile with Mt. Foraker (17,400') on the left, Mt. Hunter (14,573') in the middle, and the tallest peak in North America, Denali (20,310', formally know as Mt. McKinley and formally measured at 20,320') on the right. This trio of peaks is so prominent from the bluff overlooking the town below that we call it the **"Talkeetna Vista."** It's definition vista; a pleasing view from a high place. ![](/_images/todd/sig.png) Share: ### Photo Info Talkeetna, Alaska Nikon D800E with a Nikkor 28mm f/1.4 lens 8 sec, ƒ/1.6, ISO 2500 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Theater of Dreams | Aurora Hunter [Source](https://www.aurorahunter.com/photos/theater-of-dreams.html) [‹](/photos/the-legend.html) # Theater of Dreams [›](/photos/treasure-trove.html) ![](_pix/jaypeg/theater-of-dreams-salat.jpg) --- ## The “Theater of Dreams” Experience Like visual music, aurora bands rise above the Brooks Range of Northern Alaska at 2:30 am on April 20, 2021. This is when everything is singing together: the moon & stars, auroras & mountains, the trees & me. It’s like being in a “Theater of Dreams,” and this dream comes true. To me, this is more than just a photograph. Each compositional element strikes a chord and together they harmonize with feeling & emotion. The entire night is a concert with a beginning, a crescendo, and an end. The moon provides a consistent base rhythm as it slowly glides across the sky while the auroras create periodic riffs, occasionally amplified by explosive bursts of light & color. I’ve never studied music theory and did not even know there were seven main harmonies of music, but I’d call this a 7-part harmony. In the intro I listed six elements... so the 7th must be you. It’s like knowing a good song when you hear it. The only instrument I play is the camera, but when I see harmony in nature my eyes light up and I can feel that beat resonating deep within. This image is my ticket stub, something preserved in my photo album to help spark the memory of standing in this moonlit mountain theater and seeing this amazing concert live. The dancing aurora band's brilliant performance always leaves me at the end chanting, “One More Song!” ![](/_images/todd/sig.png) Share: ### Photo Info Auroras swirl above the Brooks Range of Northern Alaska at 2:30 am on April 20, 2021 as the setting moon reflects on the ice below.

The night of April 6, 2014 was that great and that powerful! It was night #5 of the hunt and two aurora-generating CMEs (coronal mass ejections) were due to impact earth… but the anticipation was rapidly getting thwarted as thickening clouds rolled in and smudged the sky. I dove into a good book to help pass the hours. By 3 am I was just hanging onto that last strand of hope when the clouds began to turn green. The show had begun but it was barely visible! And then the good witch of the north granted a wish and a miracle happened; the clouds parted and the northland got lambasted by an hour of power as stunning northern lights filled the night sky with color. I was on the road to Ester Dome, just outside of Fairbanks, and it was from this elevated vantage point upon which I was fortunate enough to seize this precious moment. At 4 am tall aurora rays erupted above a conglomeration of communication towers on top of the hill. A profile of a face materialized out of thin air and all that was missing was the booming voice of the Wizard of Oz telling me I need only look inside to the find the night vision for which I yearn. So I clicked my bunny boots three times... Constellation note: The series of stars in front of the "face" of the aurora that form a backward-shaped question mark are the head and forepaws of Leo the Lion. These, too, appear to be looking down on a fairy tale miniaturized city. "Towering" sights indeed. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Turnagain Nights | Aurora Hunter [Source](https://www.aurorahunter.com/photos/turnagain-nights.html) [‹](/photos/tree-of-life.html) # Turnagain Nights [›](/photos/valley-of-light.html) ![](_pix/jaypeg/turnagain-nights-salat.jpg) --- ## The “Turnagain Nights” Experience This is a story about a sunspot; a big, bold and beautiful sunspot that sparked huge auroras around Earth as it sprayed the galaxy with plumes of solar charged particles in early March 2012. Like an active volcano crackling with intensity the sunspot rolled around the sun's eastern limb (left side) and became geoeffective; it was pointing toward earth. Daily solar flares and CME's (coronal mass ejections) made world news for over a week as the sun announced it was in the peak phase of its approximate 11-year solar cycle. Every time a fresh gust of solar wind impacted earth a new outburst of auroras was created. These "geomagnetic storms" were breathtaking. On the morning of March 12, 2012, I was 50 miles southeast of Anchorage along the Seward Highway, standing on the frozen tip of one of Alaska's coveted fjords, the Turnagain Arm, when the sky turned to brilliance. It was 3:45 am and a late rising moon climbed over the Kenai Mountains, casting a welcome glow into the valley as an enormous aurora curtain migrated into the southeast. The earth's magnetic field lines were revealed as electrons spiraled in a downpour of energy and left painted trails of red and green light in their wake. The lights of Portage Junction twinkled in the distance as the moon beamed, snow crunched and the curtain shimmered. It was a full sensory impact. ![](/_images/todd/sig.png) Share: ### Photo Info Turnagain Arm, Alaska Nikon D700 with a Nikon 17-35mm f/2.8 lens 2.5 seconds, ƒ/2.8, ISO 1250 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Venus Transit | Aurora Hunter [Source](https://www.aurorahunter.com/photos/venus-transit.html) [‹](/photos/valley-of-light.html) # Venus Transit [›](/photos/whirled-view.html) ![](_pix/jaypeg/venus-transit-salat.jpg) --- ## The “Venus Transit” Experience  On June 5, 2012, from atop a parking garage at the University of Anchorage, Alaska (UAA), I watched the “Venus Transit” along with hundreds of other enthusiasts.  Alaska was in prime position as Venus, the second planet out from the sun, aligned itself directly between the earth (3rd planet out) and the sun, creating a little black dot that gets more amazing the more you think about it.  This is our solar system in rotational action and this particular celestial alignment will not occur again until the year 2117. In, perhaps, the most gorgeous weather of the year, the transit began at 2:06 pm as Venus appeared on the left side of the sun and slowly moved across the solar disc for the next 6-1/2 hours.  Venus has almost the same diameter as earth and is 1/30th the diameter of the sun.  During the transit, Venus is 27 million miles away from earth and therefore appearing quite small.  This provides a perspective for how enormous our sun is which is 93 million miles away from us.  Venus, being closer to the sun, is much hotter than earth: 900° F, hot enough to melt lead! I took the photograph “Venus Transit” at 7:42 pm AKDT as Venus was exiting along the right limb of the sun.  To get a proper exposure I placed a pair of “eclipse glasses” over the lens.  Dark as a welder's mask, these little 3D looking glasses block 99.999% visible sunlight and all the harmful UV.  My retina thanks UAA for having these available so my eyes will live to see another day. ### Sun Spots The aurora hunter in me was also excited to see the visible sunspots, those other black specks in the middle of the sun.  As we approach “solar max,” sunspots and solar flares become more common which means more [aurora activity](/solar-cycle.html)! ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Winter's End | Aurora Hunter [Source](https://www.aurorahunter.com/photos/winters-end.html) [‹](/photos/white-satin.html) # Winter's End ![](_pix/jaypeg/winters-end-salat.jpg) Share: ### Photo Info Alaska Range Nikon FM with a Nikkor 28mm f/1.4 lens 4 seconds, ƒ/1.4, ISO 200 --- ## The “Winter's End” Experience It’s April in the Alaska Range, "**Winter’s End**," and the long, cold dark season is being replaced by light and warmth (defined as anything above 32° F).  The overburden of white stuff is slowly thinning and releasing the young spruce trees from their snow-packed tomb.  I’m in my truck camper sleeping and waiting patiently for those precious few hours of fading darkness, hoping to catch one final glimpse of the aurora before the bright lights of summer hit. Midnight comes and goes and, in the blink of an eye, the orange glow of a sunset belongs now to a sunrise. The north/northeastern horizon is getting brighter as 2 am nears - there’s only an hour or two left of the star-studded skies and the quasi-darkness needed for aurora shooting.   I feel, truly feel, the elements coming together.  They’re pulling me in as I pre-visualize an ideal composition.  I count over ten natural elements:  snow, trees, moonshadows, valleys, peaks, sunrise, blue-to-black skies, stars, Venus setting, clouds, and the aurora ~ where’s the aurora?   I need the aurora element for completion. And then it happens, the forces of nature pull their trigger and all heaven breaks loose.  A green glow emanates from the east (right of photo) and soon smoky green auroras curl higher and higher into the sky.  I get off three shots.  As the aurora moves overhead I crank up the tripods and get underneath the cameras and shoot straight up.  Only a few minutes have elapsed but I’m already breaking a sweat, unzipping my parka and letting it fly.   The auroras surge north/northwest (straight ahead in this photo) and appear to touch the mountains as they continue on their 50-300 mile high circum-polar journey around our planet.  My adrenaline races when I realize this is the composition I had pre-visualized! I grab a tripod with each hand, dosie-doe into position and compose the "elements" shot, making sure to include those endearing little spruce trees in the foreground.  At that moment everything is singing and I feel another natural element being added to the scene ~ the human element. ![](/_images/todd/sig.png) Share: ### Photo Info Alaska Range Nikon FM with a Nikkor 28mm f/1.4 lens 4 seconds, ƒ/1.4, ISO 200 --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Wondering | Aurora Hunter [Source](https://www.aurorahunter.com/photos/wondering.html) [‹](/photos/white-satin.html) # Wondering ![](_pix/jaypeg/wondering-salat.jpg) --- ## The “Wondering” Experience It was an all-nighter at Wonder Lake in Denali National Park & Preserve. I considered it a spiritual retreat of sorts. My friend, Bubba, and I started that June evening wandering around the lake, taking pictures of wildflowers while Denali (Mt. McKinley) was socked in behind clouds. The only company we had were a few zillion skeeters and a couple of grizzlies that stood up and gave us a good, solid look before loping off. It appeared they had courtship on their mind. In the midnight hours we sat on Ansel Adams Point praying that Denali would come to us and in the dawn’s early light it did. We took many shots but the one that caught my fancy was Denali on its head reflecting off of Wonder Lake. A fish ring marks the water surface. Ahhh ~ the wonder of it all. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # WOW With Out Words | Aurora Hunter [Source](https://www.aurorahunter.com/photos/wow.html) [‹](/photos/white-satin.html) # WOW With Out Words ![](_pix/jaypeg/wow-salat.jpg) --- ## The “WOW With Out Words” Experience The clouds were keeping me from going further... further north into the Brooks Range and my destination, Atigun Pass. I'd been there before, and I had to come back. It is so serene, so majestic, it's God's country - the epitome of Alaska, The Great Land. The weather cleared at dawn as I crested the 4800' continental divide, highest and northernmost highway pass in AK. The snow plow operator told me it was 10 below. I wished I wouldn't have asked. At least the bears would be hibernating, I hoped. I slept the rest of the day away. Stardate: October 26, 2001. I was snug as a bug in a camper when I awoke at 7pm that evening. I peeked out the window and (Oh my gosh!) the auroras were active already. No time for breakfast tonight! The wind whipped my face as I set up my tripods and I knew I was going to have to earn this one. The auroras starting ripping across the sky as they began their color and shape shifting routine, a routine that is never the same. And then it hit. Like "W.O.W." With Out Words. There are no words to truly describe a major auroral experience. It is like trying to describe something divine. Imagine this: A beautiful rose colored glow slowly developing over the mountains. A half moon rising and trying to peek through the clouds, and finally succeeding. The white treeless slope of a pedestal-like mountain projecting black & white, rock and snow. I'm looking for more words... translucent teal and midnight blue sheltering a crimson glow that is without question one of the most gorgeous sights I have ever experienced. It was a gift from nature. And now, I am With Out Words. ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Wrangell Eruption | Aurora Hunter [Source](https://www.aurorahunter.com/photos/wrangell-eruption.html) [‹](/photos/white-satin.html) # Wrangell Eruption ![](_pix/jaypeg/wrangell-eruption-salat.jpg) --- ## The “Wrangell Eruption” Experience Please stay cold.  I was surprised to hear myself wish for this as I stuck my head out the camper door and squinted northward into the gathering darkness. A late February high-pressure system had slid over from Siberia and was pouring its chilly air onto the Wrangell Mountains, effectively keeping all clouds at bay.  Staying cold meant continued clear skies and that's the first order of business when [aurora hunting](/aurorahunting-tips.html) (myth buster: it does not have to be cold for the auroras to form, it usually just is when it's clear enough to see them). Earlier in the day I faltered a bit while fueling up at Kenny Lake Mercantile when the attendant told me it was hitting forty below at night (that would explain the stingingly numb fingers and toes and why my eyelid kept sticking to the camera last night!).  I never take a thermometer with me on these trips-I find it easier on my psyche if I don't know the temp.  Ignorance is bliss. In the crystal clear cool air the stage was set.  The spruce-lined Willow Lake glowed in the bright moonlight and somewhere in the distance ice pans sluggishly flowed down the mighty Copper River.  A string of volcanic pearls-Mts. Drum, Sanford, Wrangell and Blackburn-provided character profiles for the skyline. After a couple of uneventful nights I began to wonder if the auroras had received their invitation. But around 8pm on the third night a green wave knocked on my door and about caught me off-guard (that's way early).  Luckily for me I got that wake-up call!  Soon after, I was clocked on and in position when the aurora erupted above Mt. Blackburn and swirled across the sky like plumes of light caught in some form of interstellar turbulence. The invigorating combination of adrenaline and natural awe was enough to take the chill out of the air as I took in the magnitude of the **"Wrangell Eruption." ** ![](/_images/todd/sig.png) Share: --- ### AuroraHunter Gallery - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --- ### Related Northern Lights Pages [### Northern Lights Forecast](/northern-lights-forecast.html) [### Aurora Borealis Facts](/aurora-borealis-faq.html) [### What are the Northern Lights?](/what-are-the-northern-lights.html) --- --- # Northern Lights Science and How To - Aurora Hunter [Source](https://www.aurorahunter.com/science.html) # Northern Lights Science and How To [## Northern Lights FAQs Answers to the most popular questions I've received over my years of aurora hunting.](aurora-borealis-faq.html) [## Aurora Hunting Tips Find out when, where & how to view the northern lights.](aurorahunting-tips.html) [## Photographing the Northern Lights Learn more about getting the shot, setting up your camera, and how to photograph your own aurora borealis.](photographing-the-aurora.html) [## What Are the Northern Lights Learn what generates this amazing phenomenon.](what-are-the-northern-lights.html) [## Moon Phases Is it waxing or waning?

Hi Todd, Wanted to let you know the picture arrived in perfect shape!!! Thanks so much for all your effort. Hopefully I can get moved back up to AK in the future and add to my Todd Salat collection! Best Wishes, *Karen in MO* Hi Todd, I was just taking a look at the photos that you have on the Aurora Hunter website, and I just wanted to let you know that those are the most beautiful pictures I have ever seen. My husband and I went to Alaska on our honeymoon in July and we just fell in love with it. Since then, I have been searching the web for authentic northern lights pictures, and let me tell you I have seen some pretty interpretive work. Your photographs are beautiful, and I plan on buying a few of your pictures! Just wanted to let you know your work is appreciated! *Brittany in ID* Hi, I just wanted to let you two know how much I've been enjoying your book. It arrived just in time for Christmas. I just can't imagine how much work you've put into it. Todd, I hope remembering those cold, cold nights is a little more bearable now when you see the compilation of those pictures. It is truly amazing what Mother Nature has to show us and most of us can only look at the pictures and try to imagine what you have seen firsthand. Good luck with the book sales and I hope your holiday season at the mall went well. Take good care. I will be checking in on your site from time to time to see your new pictures. From *Larry in PA* Todd, We received the book last week. It is great! I witnessed the northern lights growing up in Minnesota but absolutely none of them were anyway near as magnificent as the ones you captured on film. Thanks for personalizing it for us. It is on prominent display in our den. Take care and keep in touch. From *Bruce in CA* Dear Todd, I have so enjoyed browsing through your aurorahunter.com website, which I discovered after purchasing one of your spectacular photo calendars on a recent visit to Alaska.

Your kindness and generosity are deeply appreciated. Happy aurora hunting to you and Shay! Most sincerely, *B.J. in CA* Thanks Todd, I received my book, Alaska's Spectacular Aurora, and it is well named. You have given me a great treasure through your eyes and the lens of your camera. I have been touched by something that I probably would never have been blessed to see in the natural. Isn't our earth a great creation? Thank you, *Gwen in NC* Dear Todd, I received your "Spectacular Aurora" from my niece as a Christmas present and just had to write you. Your pictures are truly spectacular and I can just imagine the feelings these sights must have given you. Congratulations on a truly beautiful book and continued success.

Location is determined in one of three ways: - **City in URL** — When you navigate to a city-specific page (e.g. `/northern-lights-prediction/anchorage.html`), your city name is passed to the [Open-Meteo geocoding API](https://open-meteo.com) to retrieve coordinates. No IP address is used. - **Default page** — When you visit either tool without a city, your approximate location is determined server-side, without your IP address ever being sent to a third party. On the Prediction page, location headers supplied by our CDN (Cloudflare) are used when available (city, region, coordinates, and timezone), falling back to a local, offline MaxMind GeoLite2 database on our own server; the Webcams page uses that same local MaxMind database directly, which returns city and coordinates only. Your raw IP address is never stored, logged, or shared, and is not retained beyond the duration of the request. - **"Use my precise location" button**: An optional button next to the city search box on both pages lets you share your device's own GPS-based location instead of relying on either method above. Tapping it triggers your browser's native location permission prompt. If you allow it, your precise coordinates are sent directly from your browser to [BigDataCloud](https://www.bigdatacloud.net), a third-party reverse-geocoding service, solely to look up the nearest city name. Your coordinates are never sent to our server and are not logged, stored, or used for any other purpose. This is a separate, user-initiated feature: it only runs if you tap the button and your browser's permission prompt is accepted. The location data retrieved is used solely to display a local [aurora forecast](/northern-lights-prediction.html) or [webcam listing](/northern-lights-webcams.html) and is not used for advertising, profiling, or any purpose beyond that. You can bypass IP-based lookup at any time by navigating directly to a named city page or using the city search box. ## Security We are committed to ensuring that your information is secure.
