The view from the SDO AIA 171 angstrom filter of AR 12192 moving across the solar disk.

The largest sunspot seen so far in this solar cycle produced a number of flares, even a few X-class flares, but only one rather small coronal mass ejection (CME). Here is a view of the sunspot group during the two weeks it took to pass across the solar disk
