Storm indeed! Tonight on the island of Kvaløya outside Tromsø some of the most amazing auroras that I have ever seen could be glimpsed between the rain-clouds - I halfway expected to see some aurora-rainbow :-). The colours were absolutely stunning with purple and deep blood-red in addition to the green. Here are some shots from a corona time-lapse sequence from tonight, a night I will never forget!
Nikon D3, AF-S Nikkor 14-24 mm f/2,8 at f/3,5, ISO 800-1000, exposure 3-20 secs.
