Sun in Ha – 20 April 2015

Today the seeing conditions were a bit better than yesterday. ( 3 / 10 ) There was a lot of Activity on the surface with many active areas at the moment, including a large filament. On the limb it was pretty quiet. A few very faint loop prominences were visible. It was very challenging capturing these.
