Heya,

 

Yesterday's weather was unreal it was so bad. Today, it's great. Seeing was ok, not superb though. Was able to image the large prominence grouping this morning and while watching the limb near AR2739 I noticed a prominence forming so rapidly that it would change within 30 seconds quite apparently just on the screen. I grabbed 16 videos to sequence an animation of this rapidly evolving prominence that lifted off, around 10:30am Eastern and then it was gone again. AR2739 is just a tiny spot at this point, some minor activity near it, but oh so small.

Beautiful images Marty! Yes, that row of proms is amazing. I was out there as well and also saw that lift off. Grabbed some frames. We'll see how it comes out. The wind is ferocious today! V/R Terry

That row of proms is so delicately detailed it might as well be stuff from NASA, this guy can image the sun like it’s ridiculous!

Marty -

 

Outstanding work, as always.

 

The seeing was excellent today. I was able to push my LS60 with my Brandons & a focal extender quite nicely. Proms have been terrific over the last few days.

wow the full size animation is awesome

how are you getting the surface and proms in each frame

is each a composite, or are you using curves?

Thanks all, bow.gif bow.gif

 

Happy Easter to everyone!

 

Didn't have much time, so went with Calcium this morning for a quick peak. Today's Easter sol in CaK:

No composites, I actually stopped doing composites a while back. These proms & limb were bright so I didn't have to do anything to bring them out. I did do a small shadow/highlight adjustment and some levels adjustment, but not much else.

 

Very best,
