Solar activity - July 8, 2018

Submitted by jimwcoleman

The day started out clear but high clouds quickly moved into the Pacific Northwest skies, so I couldn't do much. Here's a photo I got of some limb activity on the sun today. I have blacked out the brilliant surface to make it easier to see. I was going to photograph surface detail and add it to this image, but the clouds moved in too quickly.  All in all, a fun two hours of observing but I had to end it prematurely.

Come on summer ... where the heck are you? Oh, yeah. It's on the OTHER side of the country ...

The image looks kind of out of this world, in a good way. Your focus looks great also. I don't know how you processed it but it's really cool! Nice work Jim!!

Just normal processing with levels and curves. Using the magic wand, I selected the bright disk of the sun. Did a 20 pixel feather on it, inverted it and then deleted the white in the disk to make the edge and prominences stand out better. Pretty simple stuff. I can walk you through it sometime if you wish.
