MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1520 decayed slightly losing sunspot area and sunspot
count but is maintaining an F-type/beta-gamma-delta sunspot
group classification. 1520 produced C-class events and a
low-level M-class event during the past 24 hour period.
There remains a possibility of 1520 producing another
major flare =/>M5 in the next 24 to 48 hours.
The position of NOAA 1520 on July 14 at 15:00 UT is:
S16W32 (Solar X = 482", Solar Y = -318")

Dear RHESSI Collaborators,
NOAA 1520 has decayed somewhat following the X1.4 event.
The delta configuration has weakened since the last message
but the region's sunspot group is still classified as a large
F-type group with a beta-gamma-delta magnetic configuration.
1520 maintains the potential to produce an M-class event with
the possibility of an event =/>M5 in the next few days.
The position of NOAA 1520 on July 13 at 15:00 UT is:
S16W18 (Solar X = 281", Solar Y = -324")

Dear RHESSI Collaborators,
NOAA 1520 increased its magnetic complexity after briefly
displaying slight decay during the past 24 hour period.
The region currently has a large F-type/beta-gamma
sunspot group with a magnetic delta configuration.
1520 was the source of a major X1.4 flare at 07/12/16:52 UT.
Another major flare, =/>M5 is possible in the next
24 to 48 hours.
The position of NOAA 1520 on July 12 at 15:00 UT is:
S17W03 Solar X = 047", Solar Y = -341")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1520 has decayed slightly losing its magnetic delta
configuration but is maintaining its large F-type/beta-gamma
sunspot group. It only produced C-class events in the past
24 hour period. NOAA 1521 located just west of 1520
was the source of the largest event (C9.9 at 07/11/08:30 UT).
Despite its quiescent behavior, 1520 is capable of producing
an M-class event with a slight chance of an M-class event =/>M5
in the next 24 hour period. We'll continue the MFW for at
least one more day.
The position of NOAA 1520 on July 11 at 15:00 UT is:
S16E10 (Solar X = -158", Solar Y = -323")

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")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1515 has almost completed west limb
passage. It was the source of C-class and low-level
M-class events in the past 24 hours. It is a very dynamic
limb target with numerous limb surges and an active
prominence. Another M-class event is possible in the next
24 hours. NOAA 1520 (S15E42) remains an impressive
F-type/beta-gamma region but is still not flare productive.
An EFR located just west of 1520 at S15E38 is the brightest
plage on the visible solar disk. If it continues to develop, it may
increase the chance of flare activity in and around 1520.
1520/EFR could produce an isolated M-class event today.
The position of NOAA 1515 on July 09 at 01:00 UT is:
S17W77 (Solar X = 879", Solar Y = -288")

Dear RHESSI Collaborators,
Target region, NOAA 1515 was the source of another major flare
(M6.9 at 07/08/16:32 UT). 1515 has only slightly decayed in
the past 24 hour period. The region classification is now
an F-type/beta-gamma with a possible delta configuration.
Another major flare =/>M5 is possible before 1515 completes
west limb passage. The largest region on the visible disk is
NOAA 1520 (S15E44, -634", -287"). 1520 is classified as an
F-type/beta-gamma region. It also has the potential to
produce an event =/>M5 in the next 24 to 48 hours but so
far has been relatively quiescent.
The position of NOAA 1515 on July 08 at 17:00 UT is:
S17W73 (Solar X = 863", Solar Y = -211")

Dear RHESSI Collaborators,
Target region NOAA 1515 was the source of an X1.1 event at
07/06/23:08 UT. 1515 is maintaining bright dynamic H-alpha
plage and its F-type/beta-gamma-delta sunspot group. Another
major flare event =/>M5 is possible in the next 24 hour period.
The bright plage located in the southeastern quadrant
(S17E66, -826", -299" at 15:00 UT) appears to have a complex
E-type/beta-gamma sunspot group. This region is also capable
of producing an event =/>M5 but so far has been less flare
productive than NOAA 1515. Both regions are excellent
targets for large events in the next 24 to 48 hours.
The position of NOAA 1515 on July 07 at 15:00 UT is:
S18W59 (Solar X = 770", Solar Y = -320")

Dear RHESSI Collaborators,
Target region NOAA 1515 continues to maintain a complex
F-type/beta-gamma-delta sunspot group but has lost some
of its strongest delta configuration. 1515 was the source of
countless C-class events and a few low-level M-class events
during the past 24 hours. At this time we are suspending
the MM#018 (Region Likely To Produce Great Flares) observing
plan and return to the Major Flare Watch plan. An X-class event
=/>X5 is less likely in the next 24 hours. 1515 still has
the potential to produce an M-class event =/>M5. The large
region near the southeast limb (S17E77) could also be a source
of an M-class event.
The position of NOAA 1515 on July 06 at 13:00 UT is:
S17W44 (Solar X = 628", Solar Y = -315")

MM#018 Great Flare Watch
Dear RHESSI Collaborators,
Target region NOAA 1515 continues to maintain its large and
magnetically complex F-type/beta-gamma-delta classification.
1515 has multiple delta configurations located in the central
portion of its sunspot group. 1515 produced several M-class
events including an M6.1 at 07/05/11:44 UT, an M4.7 at
07/05/03:36 UT and an M4.6 at 07/04/22:09 UT. M-class events
expected with a possibility of an X-class event = or >X5 in the
next 24 to 48 hours. At this time we are implementing new
Max Millennium coordinated observing plan #018
(Region Likely To Produce Great Flares).
The position of NOAA 1515 on July 05 at 13:00 UT is:
S17W31 (Solar X = 466", Solar Y = -322")
