Northern Lights Alert: Aurora

That moment the sky turns green over your head. Nordlysvarsel tells you when it is worth stepping outside, so you are there when it happens.

Standing under a sky that suddenly comes alive in green and violet is something you never forget. Nordlysvarsel is here so you do not miss it.

One glance tells you if tonight is the night. You get a simple chance from 0 to 100 for exactly where you are, and the best time to head out. No guessing, no charts to decode, no cold hours waiting under clouds.

Turn on alerts and set your own level. When the aurora, the clouds and the darkness line up, your phone lets you know, so you can grab your jacket and be outside in time.

Planning a trip to Tromsø, Lofoten or Lapland? See the coming nights at a glance and pick the evening with the best odds.
