Porjus and the northern lights
Porjus is in the municipality of Jokkmokk, Norrbottens län, Sweden. It lies at 67.0° N. What counts for the aurora is the magnetic latitude, 64.9° here: under the auroral oval. Here the aurora can show from about Kp 3, against Kp 6.5 in Stockholm. Activity was that high in 20% of the hours in 2014–2025.
It gets dark enough for the aurora from 24 August to 17 April, with up to 16 hours of proper darkness a day in midwinter. Counting the darkness, that makes about 530 hours in a typical year with both darkness and enough activity, most of them in December. The clouds decide how many of them bring an aurora.
