A little breezy new years day, and time to see how the wind turbine did this year. About 17.8 MWHr's generated in 2025, so a bit down on 2024 (20.1 MWHr). Windiest month was March (1.9 MWHr)

A nice aurora last night (03-04 Dec) - massive geomagnetic shock, then over the zenith green arcs and rays. Plot and pics

The annoying thing about aurorae is when you have to shoot a comet through them. C/2025 A6 (Lemmon) and the northern lights! #aurorae #orkney #rousay #astro @theorkneynews.bsky.social

Comet c/2025 A6 (Lemmon) was visible from #Rousay #Orkney this evening. A brief gap in the cloud - but the comet was easily visible in binoculars. And here is a 4 min exposure using a Seestar S50. @theorkneynews.bsky.social @astroroyalscot.bsky.social
