In Falmouth, Maine, photographer John Stetson turned his solar telescope toward sunspot group 1271 and found it seething. "The active region is bright and crackling, surrounded by long, twisting filaments of magnetism that seem poised to produce some powerful flares," he says. Indeed,NOAA analysts note that the sunspot has a "beta-delta-gamma" magnetic field that harbors energy for X-class explosions.
