Dear Collaborators,
The target region NOAA 12904 was the source of three A-class as well as one B1.8 (at 12/07/18:56 UT) flares in the past 24 hours. 12904 retains its beta/B-type magnetic configuration but decreases the number of spots. It continues to decay and only A- and B-class activities are expected in the next 24-hour period. The position of NOAA 12904 on December 8 at 04:30 UT is: S26E13 (-197", -428") 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.
