Active aurora band

Last night was the most spectacular aurora borealis of this season. Unfortunately, the cloud ferry came in front already at midnight here in the direction of Oulu. That blue color is rarely seen in those fires.

There were also dunes among the northern lights. The shooting was not successful in the middle of the light pollution, but the shape still stands out.

Rare halos

A short distance upstream, there are large melting points. I suspect a light breeze brought ice crystals from there, which then formed that bright halo on the river.
