3-Day Forecast for Hammerfest Airport, Finnmark, Norway
Oct 13
Kp 4 is enough to bring the aurora high overhead at Hammerfest Airport, not just low on the northern horizon.
Global: NOAA has issued a watch for this night (see below) - moderate planetary activity, aurora across the high-latitude zone.
CME Watch: G1 (Minor) · Kp 5 expected
Best time to look up: 05:00–08:00 CEST
35% chance of elevated activity · Kp 4 during viewing window, up to Kp 5 depending on CME timing
Oct 14
Kp 3.7 is enough to bring the aurora high overhead at Hammerfest Airport, not just low on the northern horizon.
Global: Moderate planetary activity expected - aurora across the high-latitude zone, and lower with a good substorm.
Best time to look up: 17:00–20:00 CEST
35% chance of elevated activity · Kp 3.67 during viewing window
Oct 15
Kp 2.3 is enough to bring the aurora high overhead at Hammerfest Airport, not just low on the northern horizon.
Global: Quiet planetary conditions expected - aurora mostly confined to the far north.

Planetary K-index
Interplanetary Magnetic Field Bz-0.1 nT now
Southward (negative) Bz favors aurora. Observed data only, no forecast product exists for Bz.
Total IMF Field Bt9.3 nT now
Total interplanetary magnetic field strength - the ceiling on how negative Bz can go. A rising Bt alongside a still-fluctuating Bz often leads a stronger southward turn. Observed data only, no forecast product exists for Bt.
Global Storm Trend25 global now
Global (hemisphere-wide, not this city) prediction score over the last 24 hours, logged every 5 minutes - may differ from the Prediction ring above, which is specific to this location and time of night. Red above 70, yellow 50-70, teal below 50 - same thresholds used everywhere else on this page. Dashed line is the overall trend.
Dst History-8 nT now
Kyoto Dst geomagnetic storm index over the last 24 hours. Negative = ring-current energy stored = an active storm, not just predicted. Red below −50nT, yellow −20 to −50nT, teal above −20nT.
Solar Wind Speed & Pressure
Each line is scaled independently to its own 24h range (different units) - watch the shape, not a shared axis. A rising speed line or a pressure spike can signal an incoming stream or shock before Bz/Dst move.
Nerd Mode: See what’s really driving the score. Live solar wind, Bz, Kp, Dst, CME timing, and more. Data comes from NOAA SWPC and the Kyoto WDC, with a few metrics calculated here from the raw data. Live data refreshes every minute; trend charts every five.
