- Auroral activity on the night 2025-11-11 / 2025-11-12 associated with a period of geomagnetic activity up to Kp9 / G4 Skies in NE Scotland were affected by cloud, but there was a break in clouds that allowed view on the initial peak.. Activity was visible on camera images from around 20:50 to 03:15 UT (GMT) with peak around 23:35 to 00:00 UT (GMT).  Observed activity comprised a variety of green aurora and bright red aurora stretching to 40-50° altitude. Interesting green blobs at 01:12 - 01:13 UT (GMT). Images and video below compare colour images captured by the north facing Tapo C325WB Camera, with the black/white images captured using the existing AllSky Camera at approximately the same time.   -  Scandinavian magnetometers recorded activity from 00:00 to 05:30 UT with a peak that varied in latitude between 01:00 and 02:30 UT and lasting to 04:00 UT or so.   Lerwick Magnetometer shows activity up to K9.     - Telescope Images from 2025-11-11 >> - -

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2025-11-11 / 2025-11-12 Activity from 17:00 to 04:00 UT with initial peak of activity at 18:00 UT, with main peak in activity at 23:30 to 00:00 UT 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)
