- Weak aurora activity visible from NE Scotland on 2022-02-23 / 2022-02-24 (am).   - Scandinavia magnetometers indicate activity from around 20:30 UT to 04:00 UT with peak activity at around 23:00 to 01:00 UT.   - Activity was visible from my observatory site between 2022-02-23 22:00 UT and 2022-02-24 01:30 UT, with peak activity seen at between 23:20 to 00:45 UT - Aurora arc at around 4 to 5 deg altitude at peak with weak rays to 8 deg altitude      - Telescope Images from 2022-02-23 (S976) >>

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2022-02-10 / 2022-02-11 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)
