Darkest November to January. Outside the season the aurora is still there — the nights are just too light to see it.
Nights to watch
coarse outlook31 Oct–1 Nov Kp 5
Jokkmokk needs only about Kp 1, so any dark, clear night can work.
NOAA SWPC 27-day outlook, issued 19 Oct. It follows the Sun's 27-day rotation and can't see eruptions coming.
If you go out
Dress for −20 °C even if it says −10
You'll stand still for a long time. Wool closest to the skin, then layers, then something windproof.
Look north, away from the lights. A frozen lake or an open fell is perfect.
Give your eyes twenty minutes. To the eye the aurora is often paler than in photos — it grows as you adjust.
