MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1260 increased its sunspot area and spot count slightly
while maintaining a complex beta-gamma-delta magnetic
configuration. It continues to display dynamic bright H-alpha plage but
only managed to be the source of C-class events during the
past 24 hour period. The largest C-class event was a C5.3
at 07/28/12:12 UT. The Major Flare Watch will be in effect
for at least another 24 hour period. An event =, > M5 is
still possible.
The position of NOAA 1260 on July 28 at 10:30 UT is:
N18E24 (Solar X = -366", Solar Y = 213")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
At this time we are implementing Max Millennium coordinated
observing plan #003 (Region Likely To Produce A Major Flare).
Target region, NOAA 1260, was the source of an M1 event
earlier today at 16:07 UT. The region has continued to
grow since the M1 event adding sunspot area, count and
magnetic complexity. It has developed a magnetically complex
Beta-gamma-delta configuration. It now has the potential
to produce an event = to or > M5.0.
The position of NOAA 1260 on July 27 at 20:30 UT is:
N20E33 (Solar X = -485", Solar Y = 252")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1260 was the source of seven C-class events during the past
24 hour period. The largest was a C3.8 at 07/26/22:41 UT.
1260 added a few new sunspots but remains a D-type/beta
sunspot group. 1260 is capable of producing additional C-class
events with a slight chance of an isolated M-class event as well.
NOAA 1261 at N16E68 is a large D-type/beta
group which also has the potential to produce C-class events.
The position of NOAA 1260 on July 27 at 10:30 UT is:
N20E39 (Solar X = -560", Solar Y = 257")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1260, was the source of five B-class events
and the C1.2 event at 07/26/11:15 UT. NOAA 1261 now rotating
onto the visible just east of 1260 produced three B-class events.
The largest was a B9.4 at 07/26/03:39 UT. 1260 displayed rapid
growth during the past 24 hours. It is currently a D-type/beta
sunspot group. 1261 is still too close to the east limb to ascertain
its magnetic configuration. Both target region 1260 and 1261
have the potential to produce C-class activity.
The position of NOAA 1260 on July 26 at 15:30 UT is:
N20E49 (Solar X = -671", Solar Y = 268")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, now numbered NOAA 1260, was the source of five
B-class events since the last message. The largest was a B7.4 event
at 07/24/22:45 UT. 1260 has now completed east limb passage.
The region is currently displaying a simple magnetic configuration
with a cluster of several small spots. Additional B-class events expected
today with a chance of a C-class event as well.
The position of NOAA 1260 on July 25 at 15:30 UT is:
N20E62 (Solar X = -784", Solar Y = 284")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The several regions on the visible solar disk are very quiescent.
Solar flare activity is expected to continue at a very low level.
The target region (most likely the return of old NOAA regions 1243/1246)
has mostly rotated over the NE limb. It appears to have just
one small leader sunspot. There is weak surging in the trailing portion.
No significant solar flare activity is expected during the next 24 hour
period.
The position of the target region on July 24 at 15:00 UT is:
N19E78 (Solar X = -874", Solar Y = 290")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The regions on the disk are decaying. The target will switch
from NOAA 1254 to a new region located on the east limb.
The new region is displaying bright surges in H-alpha.
It was the source of two B-class events. The largest
was a B5.4 at 07/23/14:49 UT. Additional B-class events
expected in the next 24 hour period. There is a slight
chance of a C-class event if the region continues
in growth phase.
The position of the target on July 23 at 14:50 UT is:
N19E89 (Solar X = -893", Solar Y = 305")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a very low level. The target
region was the source of B-class events. Additional B-class
activity is possible today.
The position of NOAA 1254 on July 22 at 15:30 UT is:
S24W37 (Solar X = 520", Solar Y = -443")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity remains low. The largest event was
B8.3 produced by target region NOAA 1254 at 07/20/15:51 UT.
1254 lost sunspot area in the leading portion but gained penumbral
area in the trailing portion. It currently has a C-type/beta sunspot
group. NOAA located at N25E33 is also developing new flux in
its trailing portion. Both target region 1254 and 1259 may produce
a C-class event in the next 24 hour period.
The position of NOAA 1254 on July 21 at 15:30 UT is:
S22W26 (Solar X = 385", Solar Y = -420")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is maintaining a low level - only B-class
events in the last 24 hour period. The target region (NOAA 1254)
was the source of most of the B events with the largest
a B7.2 at 07/20/10:00 UT. 1254 is slowly increasing
sunspot area and count. The region has a D-type/beta
sunspot group and is currently displaying a weak
arch-type filament system with minor bright disk surges.
B-class events probable with a slight chance of an isolated
C-class event as well.
The position of NOAA 1254 on July 20 10:30 UT is:
S22W10 (Solar X = 152", Solar Y = -425")
