Dear RHESSI Collaborators,
Solar activity is at a medium level. The largest event since the previous message was a M1.3 flare on 16-May-2013 at 21:53, released by the target region (NOAA 11748). The main following spot has shown evidence of fragmentation over the last 6 hours. The delta spot has been stable overall, but the penumbra along the eastern boundary shows some evidence for the presence of shearing motions. There is no change to the Great Flare Watch that is currently in effect.
The position of NOAA 11748 on 17-May-2013 at 01:45 UT is:
N11E37, ( -559", 213" )
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.
