Rare halos

There was still a cloud of fog at the Hyvinkää ABC service station at 11 o'clock, although it was clear elsewhere. I stopped to take pictures of the halo phenomenon visible on the spot, which in my observations is rare.

Quiet aurora arc

Northern lights visible as colorless to the naked eye were photographed. With the camera, more colors came. In the pictures, I was amazed at the dark stripes in the main picture. Quite a clear striping of the kind I have not paid attention to in the northern lights I have seen. Isn't that normal? The striping was also visible in the pictures I took with the other camera.
