Visibility IV / V
CME again offered quite a spectacle. The cloudiness posed freezing challenges and it was up to the smallest detail so that the whole spectacle would not have been seen. The northern lights were currently spreading across almost the entire sky, offering in addition to green, red and pink hues visible to the eyes. One special feature was the so-called auroral streamer, which on the north side of the oval provided an arc-like stringy area like a substorm. Blue was also visible with the naked eye for a while in this area. In the bottom picture, these blue-toned threads. After the substorm, the sky was covered with massive CHORUS waves with various flashing and fluttering shapes.
