The Sun 2016-04-20.  Another day with restricted transparency, but a hole just big enough with thin clouds allowed me to run my normal capture targets, with seeing being around 5/10.  I thought that AR2529 would not be visible anymore, but it was still to be seen in both H-a as well as CaK.  Today three full disk images and close ups of AR2529 as well as AR2532. Solar activity is low with only one C-class flare in the last two days and the total active region area stays at 640 millionths between the two regions.
