Pictures

Panoramic View - Northern Sky

2021-11-03 21:12 UT First indications of auroral activity. Probable arc but partially hidden by clouds on northern horizon

2021-11-03 21:22 UT Brightening of aurora, part hidden by clouds

2021-11-03 21:23 UT Auroral arc brightening.

2021-11-03 21:37 UT Aurora across whole northern horizon . Display sploilt by foreground clouds.

2021-11-03 21:41 UT Activity building towards a peak, with rays visible Again part hidden by clouds and showers

2021-11-03 21:44 UT Bright aurora, but display again sploit by showers / cloud

2021-11-03 21:12 UT Aurora with upper arc to 18-20° altitude. Shower clouds

2021-11-03 21:49 UT Aurora with auroral rays to 15-20° altitude and upper arc.. Lower part hidden by cloud

2021-11-03 21:55 UT Aurora with auroral rays largely hidden by cloud.   Diffuse area of aurora in NW-WNW sky

2021-11-03 21:59 UT Aurora still active but gradually fading and increasingly covered by cloud & approaching shower/rain

2021-11-04 01:30 UT Probable Aurora associated with second peak around 01:30 but completely hidden by cloud / shower.

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)
