AR13105 and AR13107 in Ha 28th September 2022

Limited time this morning with one thing or another, so I concentrated on the two closely associated active regions 13105 and 13107 using my 150 mm double stacked refractor. The seeing conditions were reasonable, but not great, so I kept the exposures at 3 ms and added some gain to bring the brightn...

The slower rate is usually sufficient to capture the changes. O...

G2 Geomagnetic Storm 27th September 2022

After a period of relative quiet in recent days my magnetometer burst into life overnight here in the UK with the arrival of an unexpected G2 geomagnetic storm. Here are my high cadence data recorded once per second, which show the rapid fluctuations in magnetic declination recorded during the event...

Friday Sun 23rd September 2022

It got to mid-morning before I could get out to image the Sun and by then the seeing conditions were not at their best. Anyhow, the newest active regions on the south-eastern were my focus in three lights: Ha, Ca II K and 'WL' (430 nm) and I was determined to capture something before the conditions ...
