Ha Full Disk 6th April

Prominences were the order of the day on Saturday; decaying AR12737 was approaching the limb, and apart from very small polar filaments the disk was essentially blank.  All the action was on the limb though, with a number of prominences that visually were very impressive.  Taken with a Lunt50 etalon on the Coronado SM90 and the FLIR GH3 ICX814 camera.
