Northern lights tonight in Finland

Finland sits at about 67° magnetic latitude, so the aurora reaches it from roughly Kp 0.0 — most clear dark nights. The card below reads NOAA's oval, tonight's dark hours, the cloud and the Moon for Kilpisjärvi right now.

Finnish Lapland is the continental side of the same oval Tromsø sits under, and its advantage is exactly that it is not on the coast: inland air in January is dry and still, the cloud that shuts Norway often ends at the fell line, and the cold is the price. Kilpisjärvi at 69° north sees aurora on roughly three nights in four when it is clear; Saariselkä and the Inari lake district are the resort belt with dark sky ten minutes from any hotel; Rovaniemi on the Arctic Circle is two degrees further from the oval and needs Kp 3 for a proper display rather than Kp 1. Lake ice from December gives a horizon as flat as the sea.
