A free Android app that scores whether the northern lights are actually visible at your location tonight.

Landing page captured for the 2026-09-20 issue.
For
Aurora watchers planning nighttime viewing trips
Worth noticing
The visibility score discounts NOAA's OVATION probability for both cloud cover and moonlight.

Field notes

The homepage exposes the scoring model rather than hiding it behind a single opaque forecast: NOAA's OVATION probability is reduced for cloud cover and moonlight, with a stated maximum moon-related trim of 30% near full moon. It also separates three live indicators—Kp, Bz, and solar-wind speed—and describes a distinct G4+ alert for unusually strong storms visible farther south. The app is presented as free, with Google Play as the download route.
