- Auroral activity on the night 2025-10-29 associated with a period of geomagnetic activity up to Kp4. Skies in NE Scotland were affected by shower clouds  rain but were relatively clear in between times. 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 features, ..... 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  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   Lerwick Magnetometer shows activity up to K5.     - Telescope Images from 2025-10-29 >> - -
