EISCAT UHF and the Northern Lights

It's Friday, and it's soon going to be summer in the Arctic, which is a very beautiful time. A lot of the nature has been dormant during the long winter, and now it's wake-up time: the white of the snow is gone, and it is rapidly replaced by a lush green of new leaves. The birds are returning to the Arctic, and the almost complete silence of the winter is replaced by bird song and the sound of warm winds in the boreal forest.

The polar day has started, and for optical observations the nights have been too bright to see any aurora since about mid-April. However, this will not stop us from enjoying the Northern Lights.

We wish all of you a very good weekend with a photo of diffuse aurora and the Sodankylä receiver of the tri-static EISCAT UHF system.
