Dear RHESSI Collaborators,

Solar activity has increased in the past 24 hours, with a C1.6 event from the target region NOAA 12457 as well as three low- level C-class events from NOAA 12454 (N12W39; with some positive flux emerging in the negative leading spot). The target region 12457 is now classified as a beta/D-type sunspot group with increasing in sunspot area and number of spots. It continues to show flux emergence and cancellation in its southern part. C-class activities are expected from the target region and 12454 in the next 24 hours.

The position of NOAA 12457 on November 21 at 18:35 UT is:

N11E52 (Solar X = -753", Solar Y = 164")
