The forecast was correct and the Sun was out this morning, hanging in a beautiful blue sky....perfect....except that the seeing conditions were pretty poor to say the least. I managed a Ha and Ca II K FD, but absolutely could do nothing in WL. Granulation was poorly visible and the main active region was unstable on screen and I was barely able to focus.

I did manage a couple of shots on the 150mm mod earlier on, but even then the images were not the best. Anyhow it's a record of how the Sun looked this morning from the UK.

Hi

Clear spells here as well.

I observed over the house earlier than normal and saw the 3 main proms plus lots of smaller ones. In the 90mm and Quark 4.2x Chromo with 25mm Clave'.

The small ones dissapeared once things warmed up.

Also I could see the surface details in the Mak180 PST mod with the bino-viewers up to 150x, just like the image.

Cheers. Andrew.

Beautiful images Stu

Stunning view Stuart, the CaK image is a real cracker. With CaK we can see 4 maybe 5 regions where there will be new ARs forming in the next few days or weeks. Bright intense formations in plage in CaK are a real give away. We can also see a long since decayed region too. CaK is a very revealing snapshot into the birth and death of active regions.

I can see three easy active regions in your images. A fourth disturbed area lies NW the most recent active region under/around a filament located there.

Nice work Stuart!

Not fair sharing such crisp images!

I had the worst seeing in living memory!

And lots of cloud!

And all day rain tomorrow!

Thanks, Alexandra.
Hmmm.... must have pressed the 'return' key twice
CaK certainly does show where the action is, or was, or is about to be

After saying I couldn't get anywhere with my WL images (actually 430nm rather than my usual 540 nm 'continuum'), I've persevered and somehow I managed to get MS ICE to stich the four panels together (more or less). Variable seeing didn't help, and there is a stitching error on the eastern limb, but hey....

These are an excellent set Stu! I was cursing how clear and blue it was this morning, but knew you would be out observing. Glad you got this booty!

[Ivan]

Stu, you always have a great set of images.

PS Yesterday I read your instructions for creating animation. Thanks!

Hi Stu,

Lovely images. Blanket of cloud here in SE England all day.

[Martin_S]

Great Imaging Stu, I really like the hi res H-alpha through the 150 , that's amazing detail.

Great shots Stu, great detail in that HA closeup for the conditions you describe!

[Carbon60]

Many thanks, everyone. Tomorrow looks promising and AR12871 is looking good. Fingers crossed

Stu.
