Dear RHESSI Collaborators,

Solar activity is at a medium level. The largest event since the previous
message was a M3.2 flare on 17-May-2013 at 08:43, produced by the target
region (NOAA 11748). The leading delta spot maintains its configuration.
However, the main negative polarity umbra within the delta spot appears to
be no
longer completely surrounded by the common penumbra. This could either be
an
effect of possible shearing motions or the umbra being ejected from the
delta
spot (which would be unlikely). Due to the lack of major flares over the
previous
48 hours, the Great Flare Watch will end and a Major Flare Watch will now
be in
effect.

The position of NOAA 11748 on 17-May-2013 at 18:45 UT is:

N12E26, ( -403", 232" )

See http://www.SolarMonitor.org for images and
