Aurora Scanner: Aurora Tracker

Aurora Scanner helps you decide when and where to look for the northern lights. It gives a clear verdict for tonight, the main limiting factor and the strongest viewing window, keeping cloud, darkness, moonlight and aurora activity separate so a cloudy sky is never confused with being outside the aurora zone. View the latest NOAA OVATION aurora image, step through the forecast map hour by hour, and compare the aurora model with regional cloud estimates. Planning a trip? Choose your travel dates, save reachable viewing places and compare their conditions. Kp, solar wind, Bz, hemispheric power, twilight and moon data carry freshness labels. Sources include NOAA SWPC, GFZ and Apple Weather. Forecasts are estimates, not promises.
