Ysterday (May 5th, 15:00UT) I looked at the sun with my 6 inch Mak. The groups 1203/4 looked very interesting so I decided to sketch. The original sketch is mirror reversed, but I give a regular view here. Magnification was 90x.

Uwe,

Excellent observations of two interesting sunspot groups (AR 1203 and 1204). You have captured the umbra and penumbra very nicely. Thank you for sharing it with us all.

Uwe,

Another nice sketch--you've been busy. Great detail in these active regions. What kind of WL filter do you use?

Dear Erika, Frank, Carlos and Michael! Thank you for your comments.
@Michael: I use Baader Astro Solar filter foil.
