Northern Lights Tracker vs AuroraCall

Never miss the northern lights again. Northern Lights Tracker tells you whether tonight is worth going out, when to look and where to go. It turns live NOAA space weather data into one clear aurora chance for your exact location. Tonight at a Glance • Aurora chance for your location, updated live • A clear verdict, from "Go look now" to "Not tonight", with activity, solar wind, moon and cloud factors • Best viewing time and the best 2-hour window • Current Kp index and a 3-day Kp outlook • Search any place and save your favorite spots • Share tonight's forecast with friends Aurora Alerts Get notified when the aurora is likely where you are.

Will tonight be worth going outside? AuroraCall answers with one word — and wakes you up when it is. No Kp charts to decode, no jargon. One screen tells you tonight's verdict for your exact location: NO, MAYBE, YES or STRONG YES — with the best time window and which direction to look. ONE SCORE, FIVE REAL FACTORS Every night we compute a 0-100 visibility score from the things that actually decide whether you see an aurora: • NOAA's Ovation aurora oval — the physical model of where the aurora is right now • The geomagnetic forecast for your darkness hours • Cloud cover at your location, hour by hour • Moonlight washing out faint displays • Real astronomical darkness — computed on your device THE WAKE-UP CALL IS THE PRODUCT • Our servers re-score your sky every 15 minutes, all night. • You get woken only above your chosen threshold — alerts stay rare, so they stay trusted. • Within-the-hour warning: we watch live solar wind from the DSCOVR spacecraft; when it turns strongly favorable during your darkness, you get a heads-up minutes ahead — the same signal professionals watch. • G3+ storm watches: know 1-2 days early when aurora may reach far south of normal. MADE FOR FIRST-TIMERS • A 60-second guide: dark adaptation, escaping streetlights, and why your phone camera sees auroras your eyes can't at low latitude. • Solar maximum is now — the best ~18 months in two decades. Southern Hemisphere fully supported: AuroraCall points you south and tracks the aurora australis too.
