      The first is a video, captures a wider view.

      This is a nice, bright diamond dust display, rather than one formed in high cloud. It was probably caused by the snow canons at Vemdalen ski resort. These snow guns produce almost perfect crystals which contribute to the intensity seen here. Indeed, the best halos can form up to a couple of kilometres down wind from the cannons. No rare halos in the above display though. The image below gives you an idea of what they look like in operation.
