Dear RHESSI Collaborators,

Solar activity is at a low level. The largest event in the previous 24
hours was a
C6.3 flare on 19-May-2013 at 15:15, released by NOAA 11750. NOAA 11750 was
the source of other C-class activity during the period, likely due new
intermediate
spot emergence that was simultaneously observed. However, the new spots are
aligned with the main preceding and following spots, so no gamma
configuration
is visible. Yesterday's target (11748) has not produced any significant
activity in
the previous 24 hours. The region maintains its beta-gamma-delta
configuration.
The primary negative umbra within the delta spot has migrated closer to the
dominating positive polarity umbra, producing a small but strong polarity
separation line. Due to continued complex magnetic configuration and
strengthening of the polarity separation line within the delta spot of NOAA
11748,
the Major Flare Watch will continue for at least the following 24 hours.

The position of NOAA 11748 on 18-May-2013 at 17:15 UT is:

N12E01, ( -24", 232" )
