Visibility V / V

Yrjö Benson, Ursa (Helsinki)

A handsome night of fire, a feast of shapes and colors. Bright northern lights. Moderate image processing: In addition to straightening and cropping, only fine-tuning the amount of exposure and detail, with the goal of making the image fit as well as possible at night.

      Bands are usually narrower, more twisty at the bottom, brighter, and more active than arches. Bands usually develop from arches.

      Bands can form J and U shapes, sometimes even full spirals. The corona can also arise from bands. Bands are a fairly common form of aurora.
