Dear Collaborators,

Solar activity has increased since the last message. The target limb region was the source of numerous A-class events as well as a few B-class flares, with the largest one being a B4.3 at 12:24 UT today. This region continues rotating onto the visible solar disk. It is still hard to determine the magnetic configuration. Additional B-class flares are expected, with a chance of an isolated C-class flare in the next 24 hours.

The approximate position of the target on September 21 at 12:00 UT is:

N28E86 (-790", 430")

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.
