22nd May. Lots of solar activity

22nd May.
Lots of solar activity today and a clear sky ! Three images shown - first is at 540 nm showing the sunspot groups mainly in the northern hemisphere (ARs are numbered). There is a new sunspot group on the E limb that will probably be AR 3020. The second and third images are at Ha wavelength 656 nm thru a Lunt 100 scope (SS). There are lots of prominences around the limb. All three images are single exposures with a Canon 550d camera. Thanks for viewing.
