Yellowknife — The highest aurora odds in North America
Yellowknife’s geomagnetic latitude is the highest of any easily reached aurora city — the oval sits overhead almost every night. Add the flat, dry subarctic interior of Canada’s Northwest Territories and you get legendary sighting rates.
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.
