12 May Sun

12th May. A nice sunny day allowed me to take two images of the Sun's eastern limb showing AR 2822 and 2823. The first pic (yellow) shows the sunspots in these regions at 540 nm wavelength, the second pic (orange) is at 656.3 nm (Ha) wavelength. Both single exposures with a Canon 550d camera. There are some faint prominences visible at the 7 o'clock position in the Ha pic. Thanks for viewing.
