FAQ
Northern Mariana Islands: quick answers
Can you see auroras in Northern Mariana Islands?
It depends on latitude: Northern Mariana Islands's cities sit between geomagnetic 8° and 8°. 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 Northern Mariana Islands?
The Kp index is planetary — the same for all of Northern Mariana Islands. What differs is the effective local exposure (1.9–1.9 at the coming peak) and the timing, which each city page shows in its own timezone.
