Originally posted by ZoeB Igor: it's a bit of a toss up with aurora-- the best chance you'll get is when it's dark the whole night, so september to late april, but you need a clear night and solar activity, which certainly doesn't occur as often as I'd like. If you're going to northern Norway, though, I'd recommend coming around/during polar night (november 21-january 21 in Tromsų), it's an interesting experience, and we get a lot of pretty light!
Hi Zoe, thanks for the advice. I'll check how can get to Tromso and how much that would cost.
May the aurora be with you...
