MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region, NOAA 1158, was the source of a major M6.6 event
at 02/13/17:30 UT. The largest event since the M6 was a C9.4
at 02/14/12:45 UT. 1158 has a large magnetically complex
E-type/gamma sunspot group. The intermediate portion
of the sunspot group has a strong delta configuration
with an E-W magnetic inversion line. There is a very good
chance for another event equal to or greater than M5 in
the next 24 hours.
The position of NOAA 1158 on February 14 at 13:30 UT is:
S20W11 (Solar X = 174", Solar Y = -224")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
At this time we are implementing Max Millennium Coordinated Observing
Plan #003 (Region Likely To Produce Major Flares). Previous target,
NOAA 1158, entered a very strong growth phase today. It now has the
potential to produce a major flare. It has developed a magnetically
complex large E-type sunspot group with a beta-gamma magnetic
classification with a possible strong delta configuration forming
within its intermediate portion. An M5 event or greater is possible
if growth continues.
The position of NOAA 1158 on February 13 at 01:30 UT is:
S21E15 (Solar X = -236", Solar Y = -244")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, now numbered NOAA 1158, is mostly unchanged.
It was the source of a B9.6 event at 02/11/23:12 UT. The target
will switch today to east limb watch. Old NOAA regions 1147 and
1149 are returning to the visible disk. There also appears to be
a new region located nearby. This area is the source of occulted
B-class activity. The largest was a B8.6 at 02/12/01:00 UT.
This event was associated with a spectacular eruption.
Additional limb events are possible today.
The position of the target on February 12 at 01:00 UT is:
N25E86 (Solar Y = -879", Solar Y = 415")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1153 has rotated completely off the visible solar disk.
It was the source of a few minor x-ray events yesterday.
The new target region is a rapidly developing EFR located
in the SE quadrant. B-class events expected with a chance
of an isolated C-class event if the region continues to
develop. Its sunspot group is currently classified as a
D-type with a beta magnetic configuration.
The position of the target on February 11 at 08:00 UT is:
S19E35 (Solar X = -529", Solar Y = -228")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1153 was the source of 4 C-class events. The largest
was a C4.7 at 02/10/12:30 UT. 1153 could still produce an
interesting event from its position located just beyond
the west limb.
The position of NOAA 1153 on February 10 at 16:30 UT is:
N15W91 (Solar X = 938", Solar Y = 247")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1153, continued in strong growth phase yesterday
developing a beta-gamma magnetic classification later in the day.
1153 was the source of an isolated impulsive M1.9 event at
02/09/01:28 UT. 1153 also produced 3 C-class events.
The region is now too close to the west limb to ascertain its
current magnetic configuration but appears to continue to develop
displaying bright plage and a possible arch-type-filament system.
Another M-class event is possible before west limb passage.
The position of NOAA 1153 on February 09 at 16:00 UT is:
N15W80 (Solar X = 925", Solar Y = 268")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1153, has developed remarkably and is
now classified a D-type - beta region. 1153 was the source of
several B-class events since the last report. B-class activity is
expected to continue with a chance of a C-class event before
1153 completes west limb passage.
The position of NOAA 1153 on February 08 at 16:30 UT is:
N15W66 (Solar X = 859", Solar Y = 293")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1152 continues in decay phase and is now spotless.
New target NOAA 1153 has added a few small sunspots and has
started to produce minor B-class events. Additional B-class activity
is possible in the next 24 hours.
The position of NOAA 1153 on February 07 at 15:30 UT is:
N16W51 (Solar X = 728", Solar Y = 333")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is extremely low. All of the few small regions
on the visible hemisphere are stable. The target region continues
to decay. No significant flare activity expected today.
The position of NOAA 1152 on January 06 at 18:30 UT is:
S18W25 (Solar X = 392", Solar Y = -206")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1152 has significantly decayed since the last message.
It was the source of only two B-class events in the last 24 hours.
The largest was a B6.9 at 02/04/19:39 UT. Additional B-class
events are possible today.
The position of NOAA 1152 on February 05 at 16:30 UT is:
S18W11 (Solar X = 177", Solar Y = -199")
