 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.

 Halpha:

            
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.

            


            
Limb
            group in Red Wing. (Ellerman bombs are not visible on band, and
            you have to go off band to see them)
