Dear Collaborators,
Yesterday's target region NOAA 12810 (N18E08) produced a B1.3 flare over the past 24 hours. 12810 has decayed to an alpha/A-type region and seems to lose all its spots now. Today the target will switch to the northeast limb region as mentioned in the last message. This region has produced three low B-class flares, the largest one being a B2.1 at 03/20/ 15:31 UT. Additional low B-class activities are likely in the next 24 hours.
The approximate position of the target on March 21 at 08:30 UT is:
N21E73 (-820", 410")
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.
