Kp 4 is right around the roughly Kp 4 Aarhus needs - a borderline night, worth a look to the north.
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 3.3 is short of the roughly Kp 4 the aurora needs to clear the northern horizon from Aarhus.
Global: Moderate planetary activity expected - aurora across the high-latitude zone, and lower with a good substorm.
Best time to look up: 20:00–23:00 CEST
35% chance of elevated activity · Kp 3.33 during viewing window
Oct 15
Kp 2.3 is short of the roughly Kp 4 the aurora needs to clear the northern horizon from Aarhus.
Global: Quiet planetary conditions expected - aurora mostly confined to the far north.
Best time to look up: 23:00–02:00 CEST
20% chance of elevated activity · Kp 2.33 during viewing window

Planetary K-index
Interplanetary Magnetic Field Bz10.4 nT now
Southward (negative) Bz favors aurora. Observed data only, no forecast product exists for Bz.
Total IMF Field Bt11.8 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 Trend14 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-16 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.
