Theo Ramakers has been keeping his telescope and camera at the Sun and making some brilliant solar images. During the shooting on 11.Dec, he focused on Sunspots 1131 & 1133.

You might want to compare this full disk photo with the one he took 10 days ago.

Quote of his mail:

The sky cleared for an hour early in the morning today and than clouded over again. I decided to make closeup of AR1131 and 1133 and the structure of the umbra and penumbra can be seen quite nicely. In order to show this better I have included a normal version and an inverted version of the image. I also observed a few good sized but relative faint prominances and a few smaller ones.The images were made with a PST CaK and a DMK 31AU03.AS in prime focus. The close ups added a Meade 140 3x barlow in the optical train.
