Dear RHESSI Collaborators,
Solar activity has decreased to a low-to-moderate level. NOAA 11928 has rotated close to the South West limb over the past 24 hours. This region appears to be decreasing in spot area and number of spots, but some of this may be due to limb foreshortening effects. 11928 remains the largest and most complex region on the visible disk (designated a beta-gamma/E-type sunspot group classification by NOAA) and continues to produce C-class activity (a total of 4 C-class flares in the past 24 hours, the largest being a C5.3 on 23-Dec-2013 at 15:49 UT). More C-class flares are expected, with a reasonable chance for an isolated low M-class flare before NOAA 11928 rotates completely over the limb.
The position of NOAA 11928 on 24-Dec-2013 at 11:00 UT is:
S16W80, ( 924", -263" )
