Dear Collaborators,
Solar activity has been at an extremely low level with the visible solar disk devoid of sunspots. Yesterday's target region NOAA 12904 has been flare quiet since the last message. Today the target will switch to a region near the east limb, which produced a long-lasting A7.8 flare at 12/09/22:47 UT. Some low activities are likely in the next 24 hours. The approximate position of the target on December 10 at 04:30 UT is: S25E89 (-900", -420") 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.
