    • Stable Auroral Red (SAR) arc info

      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.

Kakkoskuvassa on tosi nätti SAR-kaaren osa ja sen alapuoliset vihreät läiskät.

Omaan silmään nuo läiskät näytti omituiselta, en ole aikaisemmin enkä tuon jälkeen nähnyt samanlaisia
