Dear RHESSI Collaborators,
Solar activity is at a moderate level. NOAA 11730 has maintained spot area and a beta-gamma-delta/E-type sunspot group classification while increasing in number of spots. This region has continued to produce several C-class events, the largest being a C9.6 flare on 1-May-2013 at 01:20 UT. Yesterday's target NOAA 11731 has also maintained spot area coverage, but has been reclassified as a beta-gamma-delta/E-type sunspot group. Although 11731 has produced fewer (and lower magnitude) flares than 11730 in the past 24 hours, 11731 will remain the target as it contains more high-gradient magnetic polarity inversion lines. Further C-class activity is expected in the following 24 hours, with a chance for a low M-class event.
The position of NOAA 11731 on 1-May-2013 at 10:30 UT is:
N09W09, ( 145", 216" )
