Dear RHESSI Collaborators,
NOAA regions 11542 and 11543 have both developed beta-gamma/D-type sunspot group classifications since yesterday's message. For 11543, this is mostly due to moving magnetic features fragmenting from the leading negative polarity spot. NOAA 11543 was the source of a C1.0 flare on 13-Aug-2012 at 04:05 UT. More C-class events are possible over the following 24 hours.
The position of NOAA 11543 on 13-Aug-2012 at 09:30 UT is:
N20E02, ( -28", 221" )
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.
