MM#003 Major Flare Watch

Dear RHESSI Collaborators,
 
NOAA 1618 has developed rapidly increasing its sunspot
count, sunspot area, and magnetic complexity.  1618 is currently
a large E-type/beta-gamma sunspot group with a magnetic delta
configuration located within its central portion.  1618 was the source
of 3 M-class events since the last message.  The largest was an
M3.5 at 11/21/15:30 UT.  At this time we are implementing Max
Millennium coordinated observing plan #003 (Region Likely To Produce
A Major Flare). A major flare =/>M5 is possible in the next 24 to 48
hours. There is a slight chance of an X-class event as well if 1618
continues in strong growth phase.

The position of NOAA 1618 on November 21 at 14:00 UT is:
N08E06 (Solar X = -100", Solar Y = 101")
