Active Region AR12192 erupts with an X-class flare in the visualization in the SDO AIA 171 angstrom filter.
Active Region AR12192 moved across the solar disk in late October 2014 (lower center of solar disk, around 15:00 hour time-stamp). The region fired-off a batch of flares, ranging from M-class to a few X-class flares, during this time, but only one coronal mass ejection (CME) was detected.
