Dear Collaborators,
Solar activity continues at a low level. The largest event since the last message was a C2.6 flare at 04:01 UT today produced by the target region NOAA 13599. 13599 also produced another eight ~C1 flares and three high B-class flares in the period. This region retains a beta-gamma-delta/ D-type configuration with decreasing in the sunspot area and number of spots slightly. But it is still showing some new spots in its intermediate portion. Considering that its current helicity remains at a high level, we will continue the Major Flare Watch on this region probably for the final 24 hours. C-class activities are expected with some chance of an isolated flare above M5 in the next 24 hours. The position of NOAA 13599 on March 12 at 08:30 UT is: S12W60 (819", -140") 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. Regards, Ying Li (Purple Mountain Observatory)
