- Aurora activity visible from NE Scotland on morning of 2022-04-28.   - Scandinavia magnetometers indicate activity building from evening of 2022-04-27 through to small hours of 2022-04-28., with a very short peak at 21:35 UT (2022-04-27) and a longer main peak from 00:30 to 03:00 UT (2022-04-28),    - No activity seen at 21:35 (aurora not visible or lost in twilight sky) - Activity visible 2022-04-28 00:20 to 02:25 UT (01:20 to 03:25 Local),  with peak activity between 00:40 and 01:00 UT (01:40 to 02:00 Local) Aurora arc to 5 deg altitude with rays to 20 deg altitude at peak.      - Telescope Images from 2022-04-27 >>

2022-04-27 21:35 UT (22:35 Local) Time of short peak according to Norwegian Magnetometers, but activity either not visible from NE Scotland and/or lost in twilight sky

2022-04-28 00:27 UT (01:27 Local) Weak auroral arc developing t0 5 deg altitude. Light artifact (NNW Sky)

2022-04-28 00:29 UT (01:29 Local) Auroral arc, with rays to 10 deg altitude in N/NNE sky. Light artifact (NNW Sky)

2022-04-28 00:44 UT (01:44 Local) Auroral arc brightening . Rays to 10-15 deg altitude moving along N / NNW horizon.  Light artifact (NNW)

2022-04-28 00:46 UT (01:46 Local) Auroral rays to 20 deg altitude moving along N and NNE horizon.  Light artifact (NNW)

2022-04-28 01:10 UT (02:10 Local) Auroral arc fading. Rays moving along N-NNW horizon. Light artifact (NNW)

2022-04-28 02:08 UT (03:08 Local) Rays still moving along northern horizon. Morning twilight  developing in NNE-NE sky.  Light artifact (NNW)

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2022-04-27 / 2022-04-28 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)
