MM#003 Major Flare Watch

Dear RHESSI Collaborators,

Target region, NOAA 2242, was the source of an X1.8/3b
event at 12/20/00:27 UT. 2242 is maintaining its large
complex E-type/beta-gamma-delta sunspot group and bright
dynamic H-alpha plage.  NOAA 2241, S09W16, is also an
E-type/beta-gamma-delta region but has been quiescent
since the M6.9 event on 12/18.  2242 has the potential to
produce another major flare in the next 24 to 48 hours.

The position of NOAA 2242 on December 20 at 16:30 UT is:
S18W39 (Solar X = 585", Solar Y = -282")
