Forecasts are estimates
Aurora forecasts are uncertain. Statuses, windows and scores estimate viewing conditions from public space-weather and weather data; they do not guarantee that the aurora will or will not appear. Do not rely on the site for safety decisions, travel bookings you cannot change, or anything where a wrong forecast causes harm.
Going out at night
Dark-sky spots are listed for orientation. Check access rules, road and weather conditions and opening times locally, respect private land and closures, and dress for the cold.
Data and content
Space-weather data comes from NOAA SWPC; the Kp record from GFZ Potsdam under CC BY 4.0; cloud cover from Open-Meteo; map outlines from Natural Earth. The texts, design and code of the site are ours; you may quote short passages with a link to the page.
