Dear RHESSI Collaborators,
NOAA 11598 has grown in sunspot area and number of spots. Although designated as a beta magnetic complexity, this region appears to have developed a delta spot in its lower trailing spot group. NOAA 11598 was the source of 2 major flares since the last message - an M5.0 flare on 22-Oct-2012 at 18:38 UT and an X1.8 on 23-Oct-2012 at 03:13 UT. The Major Flare Watch campaign will remain in effect, as 11598 has the potential to produce additional flares >/=M5 in the following 24 to 48 hours.
The position of NOAA 11598 on 23-Oct-2012 at 12:30 UT is:
S10E49, ( -720", -223" )
