Two years ago I visited, levi, in Finland. This villages is 200km above the arctic circle.
During this holiday we went out bed at 3.00 am to spot the northern lights, Aurora Borealis.
While taking pictures and enjoying the green lights, the light started to circle above us as you can see on the picture.
The next day we spoke with some local people and told them about the light circling above us and showed them this picture.
The most locals were very surprised they don't see it much. One of them lives there for thirty years but never seen this.
They told us this phenomenon is called "Corona".
The hart of the Aurora Borealis.
