Panoramic View - Northern Sky

2021-11-09 20:39 UT First indications of auroral activity. rays to 5-8° altitude,  moving left and right,  better seen in video. Lighting from new housing estate (N-NNE) and town (NNW) interfers with the view

2021-11-09 20:41 UT Auroral activity  rays to 5-8° altitude,  moving left and right. better seen in video. Lighting from new housing estate  (N-NNE) and town (NNW) interfers with the view

2021-11-09 22:19 UT Auroral arc to 5-8° altitude, weak

2021-11-09 22:22 UT Auroral arc to 5-8° altitude, weak, some rays moving (NNW)

2021-11-09 22:24 UT Auroral arc to 5-8° altitude, weak. Some rays moving (N - NNW), better seen in video

2021-11-10 00:30 UT Time of peak activity according to scandinavian magnetometers. Probable aurora but completely hidden by clouds

Night Summary Plot

Night Summary Plot - North Sky (2021-11-09 / 2021-11-10) Times on plot are local times (GMT = UTC +00h ) Weak activity at 20:36 to 22:43 UT, but not obvious on keogram. Probable Peak at around 00:30 UT is hidden by cloud Stray lighting from new housing estate affects keogram between 19:45 to 21:05

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2021-11-03 / 2021-11-04 Original data from Tromsø Geophysical Observatory (TGO), DTU Space (Technical University of Denmark) and Finnish Meteorological Institute (FMI, displayed on SpaceWeatherLive http://www.spaceweatherlive.com/en/auroral-activity/magnetometers). Note: Geomagnetometer activity at rvk (Rorvik, 64.95N), dob (Dombas, 62.07N), sol (Solund, 61.08N) and kar (Karmoy, 59.21N) stations are used as indicators for potential auroral activity that may be visible from my Observatory situated at latitude 57.32N  (Map of Stations)
