Crackling Action

304_crackling_Mar2011.jpg
 
 

When a substantial active region rotated into view, it was a hot-bed of dynamic motion and loops (Mar. 21-22, 2011). As observed by Solar Dynamics Observatory (SDO) in extreme ultraviolet light, the region's powerful magnetic forces tangled, broke apart and reconnected with a vengeance, even popping off a few flares. Very tight close-ups such as this one had not been possible until the SDO began operations just a year ago.
