Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 11730 emerged new magnetic flux since yesterday's message to develop a beta-gamma-delta/E-type sunspot classification and produce several C-class events (the largest being a C5.9 on 29-Apr-2013 at 20:22 UT). However, 11730 has shown considerable decay of the delta spot over the past 12 hours. NOAA 11731 shows signs of decay through fragmentation, with decreasing spot area coverage and increasing number of spots. This region has been reclassified by NOAA as a beta-gamma/E-type sunspot group and continues to be the source of C-class flares (the largest being a C3.9 on 29-Apr-2013 at 21:55 UT). Further C-class activity is expected, with a chance for an isolated low M-class event.
The position of NOAA 11731 on 30-Apr-2013 at 12:00 UT is:
N09E04, ( -72", 218" )
