Activity at the sun is very low. However there are some nice proms visible. Today a full disk imae of the Sun and two close ups of AR1839. Both made with the C11, the 3.8 Baader photographic filter augmented with a Red filter. The first was captured at f/11 while the second one was captured at f/22. Compare the size of these spots to some of the spots a few weeks ago.
