Dear Collaborators,
Solar activity remains at a low level. The largest event since the last message was a C3.2 flare at 07:44 UT today produced by the limb target region (unnumbered yet). This region also produced a C2.0 flare plus two high B-class flares. Its current helicity continues increasing when it is rotating onto the visible disk. Further C-class activities are expected in the next 24-hour period.
The approximate position of the target on December 18 at 09:30 UT is: N20E73 (-875", 330")
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.
