Northern lights tonight in Uummannaq

Uummannaq lies at 70.67° N in Avannaata, Greenland, about 458 km north of the Arctic Circle. Its geomagnetic latitude of about 78.5° puts it poleward of the usual auroral oval. Aurora here is often seen low in the southern sky, and a moderate night can show more than a big storm, which pushes the oval south. Over the long term, a dark, clear night has roughly a 46% chance of some aurora.

Darkness is never the problem in winter: the sun stays below the horizon from mid-November to late January, and nights with at least two hours of real darkness run from early September to early April. Between mid-May and late July the midnight sun makes aurora impossible to see. Around the winter solstice the sun is more than 12° below the horizon for about 16.5 hours a day.
