FAQ
Switzerland: quick answers
Can you see auroras in Switzerland?
It depends on latitude: Switzerland's cities sit between geomagnetic 46.6° and 48.3°. The closer a city is to the auroral oval, the lower the Kp it needs — each city page shows its own threshold and tonight's estimate.
Is the forecast different across Switzerland?
The Kp index is planetary — the same for all of Switzerland. What differs is the effective local exposure (3.0–3.0 at the coming peak) and the timing, which each city page shows in its own timezone.
