NASA SDO Image: Solar Flares in UV

A pair of active regions on the Sun put on quite a show over a three-day period (February 7-10, 2011), as seen in extreme ultraviolet light from the Solar Dynamic Observatory (SDO) spacecraft.

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.
