FAQ
Wallis and Futuna: quick answers
Can you see auroras in Wallis and Futuna?
It depends on latitude: Wallis and Futuna's cities sit between geomagnetic -15.2° and -15.2°. 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 Wallis and Futuna?
The Kp index is planetary — the same for all of Wallis and Futuna. What differs is the effective local exposure (2.1–2.1 at the coming peak) and the timing, which each city page shows in its own timezone.
