WL - AR2835 - JUNE 26TH TO JULY 6TH

I was fortunate to have some degree of solar time on all of these dates, and managed to get pics, varying in quality depending on scope used and seeing, for each day.  All the pics are crops taken from a single frame showing AR2835, and sometimes AR2836 before it died away. The camera was an Olympus E-M5 Mk11.

They are in date order, starting with June 26th at the top. The first seven pics, up to July 2nd, were taken with the Tecnosky 102ED F7, and the last four with the Skywatcher 72ED.  This was because generally the weather was poorer at the end of the run, and the 72ED is easier to pick up ready to go on the AZ5 and get out before any clear sky closes up.

Th pics are of course fairly low res, but I took them to obtain a record of the changes in AR2835.

This is a very impressive sequence, 11 days of evolution of these sunspots. Thanks for sharing these! I'm particularly intrigued by day 4, when 2835 has developed a dark bar, which then disappears on the next day.

Yes Nik, some days they can change quite quickly, and sometimes there is little change.   For me this is some of their interest, you never know what will happen next.

Way back pre-internet you had no way of knowing if you'd see anything at all, particularly if you hadn't looked for a while.  I can recall quite a few times lprojecting the sun with a 60mm refractor and being very surprised to see a really big group I had no idea was there. Fabulous!
