Can you see the aurora in Senja?

Yes. From a dark site you need about Kp 1 for a faint glow low on the northern horizon, and roughly Kp 3 for bright aurora directly overhead. At 66.5° geomagnetic latitude this spot sits deep under the auroral oval — quiet nights are often enough.

Over the last 12 months the planetary Kp peaked at the levels Senja needs on the days shown — out of 365. Kp is a global index, so these are the odds the sky was active enough; you still need clear, dark skies here. In 94 years on record the strongest day hit Kp 9.

When to go

The season runs late September to late March, when the nights are long and dark. You also need clear skies and a low moon — even a strong Kp is useless under cloud. Check tonight's live call above, then plan a night around the dark window, cloud and moon.

◐ Right now the nights are too bright for aurora here — true darkness returns with the season above.

Thresholds are averages from a dark site. Real visibility also needs clear skies, darkness and a cooperative moon — read every number as a chance, not a guarantee. The map is schematic: the auroral oval is drawn at a nominal 66° and the marker is approximate.
