Dear RHESSI Collaborators,
The level of solar activity remains low. NOAA 11820 and 11827 are the most complex regions on the visible disk, both being classified by NOAA as beta-gamma/D-type sunspot groups. NOAA 11820 has continued to emerge new magnetic flux since yesterday's message, producing several H-alpha optical flares in the past 24 hours. B-class events are expected in the next 24 hours, with a good chance for C-class activity if 11820 emerges more magnetic flux.
The position of NOAA 11820 on 21-Aug-2013 at 15:00 UT is:
S12W42, ( 626", -279" )
See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
