Jyväskylän Revontulet - Strong Aurora Borealis bleaching out sunlight and light pollution.

On the16th and 17th of March, 2015, a major geomagnetic storm caused massive Northern Lights. The storm was so severe that immediately after sunset, the Revontulet (in Finnish) were easily visible. Even from the light polluted city center, the Auroras were easily visible. Many locals were in awe. The show continued for several hours, until soon before sunrise.

I have shot many Northern Lights, even strong ones as these, but what I've never observed before was the on/off fast flashing coming from different parts of the sky (third scene in this video, close to real speed), truly incredible.

All the shots were made within the light polluted city boundaries of
Tuomiojärvi ranta and Kortepohja
