Was gone for most of the day, but managed to get an image in before sunset. I also gave it a first try to image the solar prominances in Ca-K. The flares were captured with very high gamma and long exposure times. I am not sure if these flares are not bleeding in from the Ha or other lines. I will have to test that with an Ha scope sometime. You also can see the rotation of the sun comparing these images to the one from yesterday.

The rain and clouds moved thru and the sun was shining again. So here an image of the Sun in Ca-K on 2010-11-17 with AR1124 at the right, 1126 in the bottom middle and AR1127 at the left.
