- Relatively weak Auroral activity on the night 2024-11-22 / 2024-10-23 associated with geomagnetic activity up to KP3. Skies in NE Scotland were generally clear in first part of night   Activity was visible from the Clair Observatory (+57N) on 2024-11-22 from 17:16 to 20:10 UT  a period of nearly 3 hours. The start of the aurora activity was hidden by twilight sky Observed activity comprised an auroral arc to 7-8°, moving curtains at times and rays to around  12-15° altitude. The aurora display coincided with the first night's use of the Observatory's new Tapo C325WB Colour Night Vision Camera. Images below compare colour images captured by the new Camera , with the black/white images captured using the existing AllSky Camera at approximately the same time.   -  Scandinavia magnetometers showed relatively weak activity -    - Telescope Images from night 2024-11-22 >>

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2024-11-22 / 2024-11-23 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)

SAMNET's magnetometer at Crooktree, Near Torphins  (Chart Explanation)  - Magnetometer activity on the night 2024-11-22/ 2024-11-23   showing increased activity with at 17:00-19:00 UT

8-day Lerwick Observatory K Index Showing max K3 on the night of 2024-11-22 / 2024-11-23

Planetary K-Index and other information (Space Weather Prediction Centre) shows KP Index reaching max KP3 on night of 2024-11-22 / 2024-11-23 Note: significant S1 peak in Solar Proton Flux  ahead of the aurora event
