March 28th. A better day today with good sky conditions. I took two pics of the Sun at different wavelengths. Orange pic is at 656 nm (Ha) thru a Lunt 100 scope and exposed for the surface features (there were few prominences anyway). The yellow pic is at 540 nm thru a herschel wedge and WO 81 mm scope to show up the sunspots better. Numbers on each pic show the AR number. Both are single exposures with a Canon 550d camera.
Thanks for viewing.
