Dear RHESSI Collaborators,
Activity has increased over the past 24 hours. NOAA 11191 has begun to rotate onto the east limb and so far consists of a large bipolar leading spot. As yet, the trailing spot is difficult to characterize as it has not fully rotated onto the disk yet. NOAA 11190 is at the central meridian and continues to experience flux emergence at its center, now classified as beta gamma. Although both of these regions have, and will continue to produce C class flares, we will select 11190 as today's target, until 11191 rotates further onto the disk. Further C and possibly M class activity possible today.
The position of NOAA 11190 on 13-Apr-2011 15:30 UT is:
N15E03 ( -48", 340" )
