Abisko — Statistically the clearest sky in the auroral zone
Abisko lies in the rain shadow of the Scandinavian mountains, in a microclimate famous for its "blue hole" of clear sky. Combined with a position under the auroral oval, it has one of the highest aurora success rates anywhere on Earth.
Fairbanks — North America’s aurora basecamp
Fairbanks sits under the auroral oval in Alaska’s dry interior — far from coastal cloud, with long, cold, clear winter nights. The University of Alaska has studied the aurora here for over a century.
