Dear RHESSI Collaborators,

Solar activity is at a low level. Yesterday's target (NOAA 11748) finally
appears to
have lost its delta configuration as there is evidence that the leading
positive and
negative umbrae no longer seem to be surrounded by a common penumbra.
While there is some evidence for minor intermediate spot emergence and NOAA
11748 was responsible for the largest flare in the previous 24 hours (a
C6.0 flare
on 20-May-2013 at 16:26), the lack of a delta configuration, significant
spot area,
and more significant activity, means that the Major Flare Watch has ended.
The
new region rotating onto the disk (now designated as NOAA 11753),
responsible
for M-class activity yesterday (an M1.8 flare on 20-May-2013 at 05:25) has
only
produced C-class activity since and is currently classified as beta/Dso. A
new
region has been rapidly emerging over the previous 24 hours in the
South-East
quadrant. Due to the region's rapid emergence and proximity to NOAA 11754,
the
new region is designated as the target. B-class activity is expected and
C-class
activity is possible.

The position of the new region on 21-May-2013 at 17:00 UT is:

S20E62, ( -786", -311" )
