Frantic upheavals

January 23, 2013
A large and powerful sunspot group (AR1654) has a dynamic and twisted magnetic field that we followed for six days (Jan. 9-15, 2013). The interactions of a pair of regions (actually two sunspot areas when viewed in filtered light) produced numerous smaller flares, while the magnetic field lines looped and snapped and flashed almost continuously. The detailed action was captured in extreme ultraviolet light. The second still and movie show the sunspots in filtered light from Jan. 10-15, 2013).
