Dear RHESSI Collaborators,

NOAA 11476 has produced multiple C-level events over the past 24 hours, as well as an M1.7 flare at 20:20 UT yesterday. The region has slowed in terms of growth but retains a sunspot area >1000 uh and a beta-gamma-delta configuration. The polarity inversion line is aligned in an almost east-west direction and there are signs of negative flux emergence within the southern positive polarity region. The chance remains for a flare of magnitude M5 or greater as the region crosses the central meridian.

The position of NOAA 11476 on 11-May-2012 at 09:00 UT is:

N12E03, ( -45", 247" )

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.
