- Aurora activity visible from NE Scotland on the evening of 2022-11-28   - Scandinavia magnetometers indicate activity at 19:00 to 22:00 UT with a very stromg peak of activity at 20:55 to 21:15, followed by a later weaker peak at 01:00 to 01:30 UT   - Activity visible from observatory at 18:40 to 21:50 UT with a very faint spell of activity after mignight between 00:35 to 01:30 UT.      - Telescope Images from 2022-11-28 >>

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2022-11-28 / 2022-11-29 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)
