Aurora is a glow caused by the interaction of Solar wind particles with the molecules of Earth’s Atmosphere.
This spectacular aurora was visible on 27th February 2014, from Iceland, South of Reykjavik.
The photo was taken with a DSLR Canon 550D and a fixed 50 mm lens.
The exposure was varied from 15 seconds to 50 seconds and the image is a HDR.
The time was around mid-night and temperature was nearly zero degrees C.
