Dear RHESSI Collaborators,
Solar activity levels have fallen slightly, with only one C class flare in the past 24 hours. This is despite the presence of 5 NOAA active regions on disk. 11416 is currently listed as the largest and most complex but has not produced any >B flares since its emergence. 11417 and 11418 are small regions approaching disk center that are currently close to spotless. NOAA 11419 and 11420 are two regions that have just rotated onto the east limb. Although it is not possible to characterize their magnetic complexity yet, 11419 has produced a multitude of occulted C class flares over the past two days and will continue to be today's target. C class flares are expected in the next 24 hours.
The position of NOAA 11419 on 13-Feb-2012 16:00 UT is:
N28 E60, (-744", 504" )
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.
