Kp 3 forecast — aurora likely, may be vivid
Stargazing in Tromsø, Norway
Tromsø is one of Europe's premier aurora destinations, sitting directly under the auroral oval at 69.7°N. During polar night (November–January), the sun doesn't rise, giving extended dark observing time — though true darkness also requires the moon to be absent. Aurora is visible on roughly half of clear nights from September through March. The surrounding Lyngen Alps and fjords provide dramatic landscapes under the northern lights. Light pollution is moderate (Bortle 5) and drops to Bortle 2–3 quickly outside town.
