Know when to look up.
Built exclusively for Northern Norway and Svalbard, AuroraChaser brings live aurora activity, cloud cover, darkness, moonlight and light pollution together in one simple Aurora Score. See when conditions look best and where to go, with 107 hand-picked viewing spots.
One score for a clearer picture:
Here in the far north, the northern lights can be overhead even when the Kp index is just 0 to 2. Kp alone doesn't tell the whole story. Clear skies, darkness and your viewing location often matter more.
Our aurora algorithm combines these conditions into a score from 0 to 100 for each individual spot:
• Live aurora probability from NOAA's OVATION model, looking toward the auroral oval as well as overhead
• Local cloud cover from MET Norway
• Darkness based on the sun's position, including polar night
• Moonlight and its effect on aurora visibility
• Light pollution at each location
Explore spots around Tromsø, Lofoten, Alta, Senja, Harstad, Narvik, Bodø, Kirkenes, Svalbard, Nordkapp and Hammerfest, Vesterålen, Lyngenfjord, Varanger and Finnmarksvidda.
Find your spot:
• Plan tonight with the peak score, best viewing window and best spot at a glance
• Open directions in your maps app with one tap, with distance and drive time shown
• Explore a live map of the auroral oval and every spot's score
• Check hourly cloud cover, a 3-day forecast and a 21-day outlook
• View live webcams before you set off
Catch the activity:
A live magnetometer indicator shows when aurora activity picks up over the region, using current measurements.
Set custom alerts for high aurora activity and solar storms, or get a daily forecast at 18:00. Set quiet hours to suit your plans and turn off any notifications you don't want to receive.
Share the chase:
• Post a sighting note and photo from the spot where you saw the lights
• Create a chase group with travel companions, with a shared feed and group leaderboard
• Browse community photos and recent sightings at each spot
• Frame your photos with your mascot, location and time
• Collect stamps, dress up your mascot and join weekly, monthly, season and trip leaderboards
