Active aurora band - 30.9.2014 at 23.40 Oulu, Oulunsalo Observation number 30824

Visibility III / V


The calm northern lights belt changed very fast for moving repos. The pillow weather provided almost perfect reflections on the lake surface. I put another picture showing four pictures taken in one minute. All part of a timelapse snippet. Good 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.
