A verdict, not a dashboard
Very good chance. Some chance. Not likely tonight. The app weighs aurora activity, clear skies, darkness and moonlight into one answer — with the “why” one glance below, if you care.
Northern lights in Iceland tonight
No Kp jargon, no solar-wind charts. One honest verdict, computed every few minutes from NOAA aurora activity, Icelandic cloud cover, true darkness, and the moon.

Why this app
Built for one week in Iceland, not a lifetime of charts
We watch the sky while you sleep
If the aurora comes out during your trip, your phone will tell you — before it fades. Set your thresholds and quiet hours; the wake-me-up alert does the rest.
One payment covers your trip
The 14-day Aurora Pass unlocks four things: wake-me-up alerts, nights three to seven of the outlook, cloud layers on the map, and tonight’s ranked best spots. Tonight’s verdict, the dark-window hours and the viewing guide are free. Pay once — there is an annual subscription too, but that one is for locals.
