There’s a nice string of sunspots on the Sun now with active regions 2321, 2324, 2325, 2326 and 2327 all visible. Prominence activity is low in Ha, but there are some fine filaments arcing around the main sunspots and further out on the north limb.

Images taken 18/4/15 12.14 – 12.27 UTC+1 using Coronado Ha PST and CaK PST and DMK41 camera. Processed in Registax 6 and Photoshop CS2.
