The full story of the sun on March 11, 2012. Active regions, prominences and a tremendous filament... all in all, a glorious day. A close-up of active region 1429 can be seen here.

This image was blogged by Phil Plait... bad astronomer extraodinaire at Discover. Compare to this full disk captured in May 2012.
