Active aurora band - 23.8.2016 at 23.15 - 23.8.2016 at 23.50 Pöytyä Observation number 56189

Visibility III / V

I hurried to the shore of Lake Savojärvi in Pöytyä, when I started to see quite strong northern lights. I got to the beach in about 23 countries and from there I started looking in the right direction and putting the camera to shake the pictures. One of them, when the northern lights were just beginning, also grabbed the image of a meteorite? Other observations when I watched, so together at least this same flight had come into the pictures. That flight was 23.15.44 as seen from the image data.

      ARC The arcs are wider than the bands and do not fold as strongly. The arcs are normally neither very bright nor active.

      The arc is probably the most common form of aurora. When aurora show is a calm arc in the low northern sky it often doesn’t evolve to anything more during night. In more active shows the arc is often the first form to appear and the last to disappear.

      The lower edge of the arc is usually sharp but the upper edge can gradually blend into the background sky. As activity increases rays and folds normally develop, and the arcs turn gradually into bands.
