I assume that you are already in northern Norway, somewhere around Tromsø or Lofoten, and that you are contemplating whether you should go out of your warm, cozy cabin or hotel.
Well, let’s put aside the idea that the best thing would be to stay in one of those fancy Northern Lights igloos with a glass roof.
Here is what I would advise you to do:
✅ Check the weather forecast. Look at the percentage of low and middle clouds. If it is a cloudless night, get ready to go out.
✅ If the weather forecast predicts close to 100% cloud cover in your location, scout for an area with fewer clouds.
✅ Keep an eye on your Northern Lights alert app (Aurora Alerts or Hello Aurora are the best mobile apps, in my opinion).
✅ Forget about the Kp index.
✅ Keep an eye on the Bz getting close to 0 or, ideally, negative.
✅ If the Bz turns negative and other parameters increase as well, then BINGO, you have about 30 minutes until something SHOULD happen.
✅ Most importantly, be patient and look at the sky more than the aurora tracking apps.
