Active aurora band - 27.9.2019 at 21.27 - 27.9.2019 at 21.51 Lempäälä Observation number 89330

Visibility III / V

At your request, I will still send pictures of Steve on September 27, 2019. In Pori, we spotted a white, lively, cross-striped arch by the sea. At first we didn’t even realize it was Northern Lights. It took minutes before we started filming it. At the edges of the reddened Steven, green, loose rays are also visible in the two images. The first of those pictures is at 9.29.57 and the last at 21.49.22.

      STEVE (Strong Thermal Emission Velocity Enhancement), Pink, radial aurora-like arc  . The STEVE arc is seen clearly separated from the main aurora arc of the northern sky. It forms a long and narrow west-east aligned, usually dim form. It does not belong to traditional auroras as a phenomenon, but may appear same time with them. Occasionally there may also be a green, "toothed" band called ”picket fence” at the bottom of Steve.

Todella hieno STEVE! Tuossa on vähän picket fenceäkin.

Nätisti näkyy Picket-Fence myös. Sitä ei täältä paljon enemmän idän suunnalta juurikaan erottanut.
