Dear RHESSI Collaborators,

The level of solar activity is low. NOAA 11909 remains the largest, most spotted and most complex active region on the visible disk. This region is classified by NOAA as a beta-gamma/E-type sunspot group, but has only produced a C1.1 flare (on 4-Dec-2013 at 22:18 UT) since the last message. Yesterday's target region (the return of X-class productive NOAA 11893) has rotated over the South East limb and produced several C-class events, the largest being a C6.2 flare on 4-Dec-2013 at 20:14 UT. This region appears to consist of spatially-extended strong magnetic flux, but no spots are visible at this time. Further C-class activity is expected in the following 24 hours.

The approximate position of this region on 5-Dec-2013 at 15:30 UT is:

S10E73, ( -917", -171" )
