Two different trips
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.
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.
