A small active area in CaK on the 9th April
An unexpected clear spell with quite good seeing (1.5-2.0 SSM reading) so I had a look at the disc in CaK, ED80 with focal reducer. The tiny active area looked interesting so I added a x3 Barlow and did a sequence of images at 15 second cadence, 30 frames, 7.5 minutes. I wondered what was going on in white light as well so took the same sequence at the same magnification with ED80 and Lunt Herschel wedge and continuum filter. There is a small pore visible in the area.
I like the strange pulsing of the animated CaK image. Sorry, they are big files but will download if you wait.

Re: A small active area in CaK on the 9th April
These are excellent Robert! You've certainly been getting some clear skies lately - certainly more than me. I did have the Lunt50 set up earlier this morning and caught a few visuals of the emerging flux region where the clouds thinned momentarily. Lots of subtle movement going on in that calcium animation.

Re: A small active area in CaK on the 9th April
Very nice animations! Thanks for sharing them with us.
BTW The pulsations, I am sure, are the mexture of the seeing and real changes on the sun.

Wow! I love the calcium K animation, you can see the spicule bases waving around, that is beautiful! to get one image that clear in CaK would be a miracle for me

Very nicely done, Robert.
I'd settle for just even seeing the Sun. More grey skies here.
