AuroraChaser: Northern Lights

Know when to look up. Built exclusively for Northern Norway and Svalbard, AuroraChaser is a northern lights forecast that 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 tonight, from Tromsø and Lofoten to Alta and Svalbard, with 124 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 forecast 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 Built on years of aurora camera records, the score shows your chance of seeing the northern lights with your own eyes. Explore spots around Tromsø, Lofoten, Alta, Senja, Harstad, Narvik, Bodø, Kirkenes, Svalbard, Nordkapp and Hammerfest, Vesterålen, Lyngenfjord, Varanger and Finnmarksvidda. Visiting Tromsø? The Tromsø region alone has 20 spots, each with its own northern lights forecast for tonight. 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 the hourly clear sky forecast, the 3-day Kp forecast and a 14-day chance forecast • 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.
