AR11967 continues to stay lively. In less than 24 hours on Jan. 28, it produced 7 M-class solar flares. The largest flare was an M4.9 at 19:00 UT. Here is a video of composite 304, 171 and 193 angstrom SDO/AIA images from 7:15 to 20:00 UT on Jan. 28, 2014. The video is rotated so that the left or East limb of the sun is at the top of the video.

AR11967 is finally completely on the disk allowing solar observers and forecasters to get a good look at its structure and magnetic complexity. The region was determined to have moderate magnetic complexity so flare forecasters are expecting more intermediate activity, C and M-class flares.
