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.
Kiruna — Sweden’s space town beneath the oval
Kiruna — home to the Esrange space centre and the Icehotel in nearby Jukkasjärvi — pairs easy flight access with reliably dark Lapland skies. It needs only modest activity (Kp 2) for overhead displays.
