Tonight an absolutely breathtaking corona with lots of structures lit up the night sky at about 22:00 local time. This spring`s aurora season is slowly drawing to an end, but maybe some of the best shows are still in store? and there are still many opportunities to see the auroras before the nights get to bright. Also mid-latitude sky-watchers should be prepared for some action. Nikon D3, Nikkor 20mm f/2,8, 8 sec exposure, ISO 1000

Stunning, sparking activity. This was a sudden outburst of activity.

For days on end, it's been cloudy and snowing in Tromsø, Norway. So when the evening seemed to clear up, I got in my car for some Aurora photographing. Theese images are from the Eiscat field outside Tromsø, and shows some of the space-radars here. Nice contrast with the Aurora. I'm using Nikon D90, Sigma 10-20, ISO 1000, 4-8 sec. exp.

These are DMSP (Defense Meteorological Satellite Program) images of a dramatic aurora event in Northern Canada. The infrared imagery is included here to show that this is really not a cloud! (Auroras are not sources of infrared radiation, but clouds are, so IR imagery can be used to distinguish the two.)
