Observed from 4.20 to 5.20pm.  I wanted to see AR3007, an interesting AR with numerous small umbral spots.  I like this sort of group as they can change quickly and sometimes develop into bigger ARs.  Now I've said this it will probably fizzle out fairly quickly 😊.  It's the unpredictability of sunspot groups which I find so fascinating.

There are actually three other ARs, but one of them diesnt appear to have been allocated a number.  It's N of AR3006.

Single frame below taken at 5.11pm, Tecnosky 1O2ED F7, Olympus E-M5 Mk11, 1/400 at 200asa.  Alas the seeing changed quite rapidly which doesn't help it.
