Why these months?

Two things decide your odds in Anchorage: darkness and activity. You need real darkness — so the bright midnight-sun months are out no matter how strong the aurora is. On top of that, geomagnetic storms run statistically stronger around the spring and autumn equinoxes (the Russell–McPherron effect), which is why September and October and February and March tend to edge out the dead of winter. Anchorage's season runs late september to march.

Anchorage is the easy-access Alaska option — a real city with flights and hotels — but it sits lower under the oval and has more light pollution, so it needs a stronger night than Fairbanks.

Where to stand in Anchorage

Get out to Point Woronzof, the Glen Alps trailhead, or drive north toward the Mat-Su valley and Hatcher Pass for darker skies.
