Half-sky auroras - 17.9.2021 at 23.00 - 17.9.2021 at 23.59 Ulvila Observation number 101318

Visibility IV / V

Vesa Puistovaara, Porin Karhunvartijat

Quite a northern lights show was recorded at the Bear Camera last night.

It was a bit of luck insofar as the camera had been off for a whole week due to a software update, but I got the job done spinning at just the right time.

After all, I couldn't properly prepare for this, even the clouds were promised ... the shooting settings were still in search.

    • 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.
