Description

Sunspot groups 2993 and 2994 on two consecutive days (more precisely: 21 hours apart).

Conditions for the first image on April 22, 2022 (left) were moderate. I was able to stack 100 out of 3000 images. The following day, conditions were really bad, clouds were moving in quickly, and seeing was terrible. Therefore I could only use 10 out of 10,000 images. The right image is therefore blurrier with an uneven brightness distribution. Nevertheless you can see the development of the two sunspot groups.
