A Memorable Aurora Over Norway.

It was one of the most memorable auroras of the season. There was green light , red light, and sometimes a mixture of the two. There were multiple rays , distinct curtains , and even an auroral corona . It took up so much of the sky. In the background were stars too numerous to count , in the foreground a friend trying to image the same sight. The scene was captured with a fisheye lens around and above Tromsø, Norway, last month. With the Sun becoming more active, next year might bring even more spectacular aurora.
