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.
