Sun in HAlpha With Lunt LS100THa Uploaded 4/23/17 Daily Report For Sunday, April 23rd, 2017
 Seeing was choppy today, however with the appearance of an additional small group on the limb, it was worth taking a look. Not much in the way of proms, however the magnetic lines of force around the spot groups was amazing.

Prime focus with the 4 inch Lunt, shows the moderate double spot group left of center, and a smaller group on the lower left coming onto the disk. A faint grey shadow to the upper left is a filament.

Longer exposure showing the proms on the limb were quite small today. The grossly overexposed disk is blackened here as to not hide the limb details.

Red wing of Halpha (about 3/4 Angstrom off band toward the IR end of spectrum) showing the main active regions. Few Ellerman bombs were seen today.
