Nordlys (aurora), over Trondheim

Aurora or northern lights called nordlys in Norwegian. An aurora is a natural light display in the sky, especially in the high latitude regions, caused by the collision of solar wind and magnetospheric charged particles with the high altitude atmosphere.

It is easy to see it in higher latitudes in Norway but not very often in Trondheim position. I wanted to take a picture where I can see the city as well. On 12th of september the aurora index was so high and it was very nicely visible over Trondheim as well. the tower in the left side of the picture called Ttyholt tårnet which has a rotating restaurant in top. From there you can see almost entire city.
