One number for your sky.
Geomagnetic activity, darkness and the clouds above you, combined into the chance of seeing the lights tonight, hour by hour.
Clouds are part of the forecast.
The next two nights, each with its cloud cover. A strong aurora behind an overcast sky isn't a show, so you see which nights are worth going out for.
A heads-up while it's happening.
When activity rises over your location, Boreal sends a notification with the chance right now, so you can step outside while it's still on.
Your coordinates, not your region.
The forecast is computed for exactly where you stand. Spin the globe to see tonight's aurora oval and how far it reaches.
