Dear RHESSI Collaborators,
Solar activity is at a low level. The region that rotated over the North East limb is now designated as NOAA 11793. This region is a large dipolar region with some early indications of polarity mixing between the primary leading and trailing spots (i.e., beta-gamma magnetic complexity). NOAA 11791 has emerged a positive-polarity spot on the Northern edge of the maturing negative-polarity trailing spots. These spots appear to share a common penumbra, which would alter the classification of NOAA 11791 to a beta-delta/D-type or beta-gamma-delta/D-type sunspot group. This region produced two C-class flares since yesterday's message, the largest being a C3.0 on 15-Jul-2013 at 03:11 UT. Further C-class activity is expected over the next 24 hours, with a chance for an isolated low M-class event if NOAA 11791 emerges more magnetic flux.
The position of NOAA 11791 on 15-Jul-2013 at 10:30 UT is:
S15E11, ( -178", -313" )
