Ha Full Disk - 16th April

An unusual sun today; despite it having quite a few sunspots on the disk it was strangely lacking in activity as a whole, and, as such, was presenting a quiet disk. Fortunately there was a good selection of proms around the limb making up for things. Taken with the 70mm PST mod @ f11 with the DMK31 camera.
