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.
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.
