Northern Lights Forecast
for Coldfoot / Bettles
Coldfoot / Bettles, USA — about 68° geomagnetic latitude. Remote far-north, very dark; fly-in.
Can you see the aurora in Coldfoot / Bettles?
Yes. From a dark site you need about Kp 0 for a faint glow low on the northern horizon, and roughly Kp 2 for bright aurora directly overhead. At 68° geomagnetic latitude this spot sits deep under the auroral oval — quiet nights are often enough.
Over the last 12 months the planetary Kp peaked at the levels Coldfoot / Bettles needs on the days shown — out of 365. Kp is a global index, so these are the odds the sky was active enough; you still need clear, dark skies here. In 94 years on record the strongest day hit Kp 9.
