Dazzling Duo
June 14, 2012
As SDO observed in extreme ultraviolet light, a pair of active regions put on quite a show over a three-day period (Feb. 7-10, 2011). The magnetic field lines above the regions produced fluttering arcs waving above them as well as a couple of flares. Another pair of smaller active regions emerges and trails behind the larger ones.
