MM#003 Major Flare Watch

Dear RHESSI Collaborators,

NOAA 1520 increased its magnetic complexity after briefly displaying slight decay during the past 24 hour period. The region currently has a large F-type/beta-gamma sunspot group with a magnetic delta configuration. 1520 was the source of a major X1.4 flare at 07/12/16:52 UT. Another major flare, =/>M5 is possible in the next 24 to 48 hours.

The position of NOAA 1520 on July 12 at 15:00 UT is: S17W03 Solar X = 047", Solar Y = -341")
