- Auroral activity on the night 2024-11-24 / 2024-10-25 associated with geomagnetic activity up to KP3 Skies in NE Scotland were generally clear, but conditions were particularly windy.   Activity was visible from the Clair Observatory (+57N) on 2024-11-24 from 22:10 to 03:30 UT  a period of nearly 5 hours. The end of the aurora activity was possibly hidden by developing clouds. Peak activity was a 15-20 min period around 23:40 to 23:55 UT Observed activity comprised moving curtains and red coloured rays up to 15-20° altitude. Later on an auroral arc up to 5-6° altitude was evident The aurora display was recorded using the Observatory's new Tapo C325WB Colour Night Vision Camera, with images processed in real time by a new AstroColorCam program built for handing the frames captured by iSpy. 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 record activity from 22:00 to 04:00 UT. -    - Telescope Images from night 2024-11-24 >>

Pictures (AllSky Camera)  - Under Construction

Panoramic View - Northern Sky

2024-11-24 22:14 UT (GMT) First sign of aurora with a coloured glow along northern horizon Light pollution in centre of image (NW) is from nearby town.

2024-11-24 23:19 UT (GMT) Aurora arc with bright red rays in N-NNE sky Bright stars are Vega (Lyra) & Denab (Cygnus)

2024-11-24 23:42 Increase in auroral activity, increase in red glow with distinct red rays in NW Sky

2024-11-24 23:47 UT (GMT) Curtains and bright green / red rays in N-NNW sky

2024-11-24 23:50 UT (GMT) Continuation of rays in N-NNW direction, but less bright

2024-11-25 02:21 UT (GMT) Green aurora arc continuing along northern horizon to 4-5°altitude Weaker activity than before with no red colours

10 x 50 ms stacked exposures over 30s intervals taken with Tapo C325WB Colour Camera vs 30s exposures taken with Oculus All Sky Camera
