- Brief but intense aurora activity visible from NE Scotland on 2022-03-13 (late pm). View unfortunately spoilt by cloud and moonlight.   - Scandinavia magnetometers indicate activity building from 11:00 in morning with peak activity at around 23:00 to 00:30 UT.   - Activity was visible from my observatory site between 2022-03-13 23:00 UT and 2022-03-14 00:30 UT, with peak activity seen at between 23:25 to 23:40 UT. - Aurora arc up to 25-30 deg altitude with rays to 40 deg altitude at peak. - Activity was part of a G2-class geomagnetic storm that was associated with an earth-directed coronal mass ejection (11 Mar 2022 CME, 22:32) hitting the earth's magnetic field on 13 Mar.

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2022-03-13 / 2022-03-14 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)
