MM#003 Major Flare Watch

Dear RHESSI Collaborators,

NOAA 1515 has completed west limb passage.  It was
the source of a few minor events yesterday.  The new
target is NOAA 1520.  1520 is a very large region with
a complex F-type/beta-gamma-delta sunspot group.
Its H-alpha plage is displaying bright flare points and
dark surges. Previously somewhat quiescent, 1520
produced 3 M-class events in the past 24 hour period.
The largest was an M2.0 at 07/10/06:27.  Additional
low-level M-class events expected with a major =/>M5
 event possible in the next 24 hour period.

The position of NOAA 1520 on July 10 at 15:00 UT is:
S17E24 (Solar X = -368", Solar Y = -332")

See http://www.SolarMonitor.org for images and

for a description of the current Max Millennium Observing Plan.

Regards,

Bill Marquette (Helio Research)
