Frequently asked questions

The KP index measures geomagnetic activity on a scale from 0 to 9. Higher values indicate stronger disturbances in Earth's magnetic field, which create more intense and widespread auroral displays. KP 7 represents a strong storm where auroras are visible at lower latitudes.
Our forecast combines real-time solar wind data with advanced geomagnetic models. For KP 7+ events, we achieve 92% accuracy with a typical lead time of 60-90 minutes. Accuracy decreases for lower KP levels due to atmospheric variability.
While darker skies improve visibility, strong auroral activity (KP 6+) can be seen even with some light pollution or twilight. For KP 7+ storms, the aurora is often bright enough to be visible under moonlight or in areas with moderate light pollution.
Aurora season runs from late August to mid-April in the Northern Hemisphere, when nights are sufficiently dark. Peak activity typically occurs around the equinoxes (March and September) due to increased solar wind interactions with Earth's magnetic field.
Yes, all paid plans are month-to-month with no long-term contracts. You can cancel anytime from your account settings, and your access will continue until the end of your billing period.
We provide global coverage for all inhabited landmasses. Our hyperlocal predictions work anywhere with GPS coordinates, from urban centers to remote wilderness areas. Service includes all countries where auroral visibility is physically possible.
