Northern lights over Sweden
Aurora forecast based on the Kp index — a measure of geomagnetic activity (scale 0–9). The higher the Kp, the further south the aurora can be seen. Best chance with a dark, clear sky and an open view to the north.

Tips for seeing the aurora
- Seek darkness — get away from city lights.
- A clear view to the north.
- Clear skies: check the cloud forecast first.
- The best time is usually 21:00–02:00.
- Let your eyes adjust to the dark for 15–20 min.
- A camera often sees faint aurora before the eye does.
What is the Kp index?
The Kp index measures disturbances in the Earth’s magnetic field on a scale of 0–9. At
Kp 3–4 the aurora can be seen in Norrland, at
Kp 5+ (geomagnetic storm) all the way down to Svealand and Götaland. The values are updated every three hours.
