Över hälften av himlen täckt av norrsken - 4.11.2018 at 21.22 - 4.11.2018 at 22.05 Smedjebacken, Ruotsi Observation number 101707

Visibility IV / V

I saw the green northern lights clearly and clearly with the naked eye. When I took a picture, I realized that it was more than green light and I danced with happiness as it was the first time the only time I caught a red light in a picture. It was also straight south. Long large arc across the sky with red light, å. Only in the north it was green. Total happiness :)

      The Stable Auroral Red arcs (SAR arcs)  are usually clearly distanced to the south from the aurora oval and is a very opaque and normally red ribbon. In most cases SAR arcs are only visible in the photo or on the liveview screen of the SLR camera. Using a camera with very high sensitivity is the best method for capturing these faint arcs. The arch usually settles between east and west.

      A stable red arc of aurora is a rare phenomenon. In some rare occasions, several SAR arcs may be simultaneously visible.

      The first SAR arcs of the Skywarden were observed on nights between November 3-4. and 4-5. days in 2015 in the latitudes of central Finland.   

      SAR arc photographed by Lasse Nurminen 2018. Observation of the Skywarden 79113.
