Northern lights tonight in Alaska

Alaska sits at about 66° magnetic latitude, so the aurora reaches it from roughly Kp 0.3 — most clear dark nights. The card below reads NOAA's oval, tonight's dark hours, the cloud and the Moon for Cleary Summit, north of Fairbanks right now.

Fairbanks sits under the auroral oval itself at about 65° magnetic latitude, which is why it sees aurora on most clear dark nights from late August to mid-April and needs no storm at all — Kp 1 puts the arc overhead. The problem here is never the oval; it is the sky: interior Alaska's ice fog and −30 °C nights, and eighteen hours of dark in December that shrink to a few by April. Cleary Summit and Murphy Dome stand above the valley inversion and look north over nothing. Denali's park road is darker still but closed past Savage River in winter.
