About
Will you see the northern lights tonight? AuroraPulse answers with one number: your chance, from where you are, right now.
YOUR CHANCE, NOT JUST A KP
AuroraPulse combines the planetary Kp index with your geomagnetic latitude, the cloud above you and how dark the sky is. A high Kp means little under an overcast sky or at noon, and the app says so.
LIVE AURORA MAP
See the auroral oval from NOAA's OVATION model on a real map, where you stand in relation to it, and which way to look.
FORECAST
• 3-day Kp forecast with the windows when aurora could reach you
• 27-day outlook for planning a trip
• Compare a destination: what Kp it needs and the cloud forecast
ALERTS THAT RESPECT YOU
• One evening notice when aurora is forecast for your location
• Optional alert 30 minutes before the peak
• Geomagnetic storm and Earth-directed CME alerts, filtered to what can be seen at your latitude
SPACE WEATHER, EXPLAINED
Solar wind speed, Bz, X-ray flares, sunspot number and active NOAA storm bulletins, with a guide that explains what each number means.
WIDGETS AND LIVE ACTIVITY
Home Screen and Lock Screen widgets, a Live Activity when aurora is possible, and Siri: "What's the aurora forecast in AuroraPulse?"
COMMUNITY SIGHTINGS
See recent reports near you and add your own. A sighting shares an approximate location (about 10 km), never your exact position.
PRIVATE BY DESIGN
No ads, no tracking, no sign-up. Your location is used on your device; weather requests use it rounded to about 1 km.
Data: NOAA Space Weather Prediction Center, NASA DONKI, Open-Meteo.
