The First X-class Flare of 2015!

Active Region 12297 was the site of two M-class flares yesterday and an X2.1 starting today at 1611 UTC (12:11 p.m. ET). AR 12297 is in the southern hemisphere of the Sun. This movie in the AIA 304 Å shows about 90 minutes of time that includes the flare. Note the ribbon of material that lifts off the surface.
