Northern lights tonight in Sisimiut

Sisimiut lies at 66.94° N in Qeqqata, Greenland, about 42 km north of the Arctic Circle. Its geomagnetic latitude of about 75.0° 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 60% chance of some aurora.

Nights with at least two hours of real darkness run from late August to mid-April. Around midsummer the sun does not set at all (early June to early July), and the light nights either side rule out aurora. Around the winter solstice the sun is more than 12° below the horizon for about 15.5 hours a day.
