A short window of opportunity opened this morning between the heavy clouds and showers giving me the chance to see first-hand the beautiful sunspot groups that make up AR2673 and 2674.
AR2673 is currently putting on a fabulous display with a significant surge prom shooting thousands of km above the surface. I managed to capture the solar fireworks using my 150mm/DS Lunt 35 operating with a Basler acA1920155um camera on a 2.5x Powermate giving a focal ratio of about f35.
Here are the resulting images in several flavours......
H-alpha, WL and Ca II K imaging kit for various image scales.
Fluxgate Magnetometers (1s and 150s Cadence).
Radio meteor detector.

Many thanks for your comments, guys. I really appreciate the feedback.
Back to grey skies here

Pity I missed the looping proms. Nothing but thick clouds and heavy rain showers since I took these.

Excellent shots there Stu! Glad you've managed to get some sun!

Wow! I think that is the biggest surge I have ever seen
We got some gaps yesterday but then it would rain within 10 minutes of them and not light rain either, it just wasn't possible. Of course I am sure we will have a beautiful clear and sunny weekend the next time the Sun is completely quiet
