MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1564 switched to growth phase developing
a large leader spot. Its sunspot group is classified as a
large E-type/beta. 1564 was the source of C-class
activity and an isolated M1.4 x-ray event at 09/08/17:59 UT.
C-class events probable with another isolated M-class event
possible in the next 24 to 48 hours.
The position of NOAA 1564 on September 09 at 13:00 UT is:
S13W47 (Solar X = 680", Solar Y = -293")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1564 added some penumbral area since the last
message. 1564 is a large plage with numerous widely
scattered small and medium-sized sunspots. Its sunspot
group is currently classified as an E-type/beta. C-class
events possible in the next 24 hours.
The position of NOAA 1564 on September 08 at 09:00 UT is:
S13W33(Solar X = 507", Solar Y = -311")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1560 produced C-class activity during the
past 24 hours. The largest was a C3.7 event at 09/07/00:45 UT.
1560 is starting west limb passage. We will switch back to
NOAA 1564 today. 1564 has lost most of its magnetic complexity
but is maintaining bright H-alpha plage and is the source of
C-class activity. C-class events probable with only a very
slight chance of an isolated M-class event in the next 24 hour
period.
The position of NOAA 1564 on September 07 at 13:00 UT is:
S14W21 (Solar X = 332", Solar Y = -338")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1564, S14W07, is mostly unchanged and
continues to be the source of C-class activity. The largest x-ray
event in the past 24 hours was an isolated impulsive M1.6
at 09/06/04:30 UT. The source region was NOAA 1560.
1560 (E-type/beta-gamma classification) has also produced
numerous C-class events since the last message. We'll
switch target regions from 1564 to 1560 for the next 24 hour
period. C-class events probable with the chance of another
isolated M-class event.
The position of NOAA 1560 on September 06 at 13:00 UT is:
N04W66 (Solar X = 868", Solar Y = 017")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1564 has decayed significantly losing some spots and
penumbral area and magnetic complexity. It is now classified
as a D-type/beta region. It was able to produce C-class events
in the past 24 hours. Additional C-class activity possible with
an isolated M-class event now less likely in the next 24 hour
period.
The position of NOAA 1564 on September 05 at 13:00 UT is:
S14E06 (Solar X =-096", Solar Y = -345")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1564, added sunspot area and sunspot count
since the last message. It is now an E-type/beta-gamma
sunspot group with numerous small sunspots and bright
H-alpha plage. 1564 is currently producing C-class events.
Additional C-class events probable with a slight chance of an
isolated M-class event in the next 24 hour period.
The position of NOAA 1564 on September 04 at 13:00 UT is:
S16E18 (Solar X = -283", Solar Y = -371")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1560, N03W25, has decayed somewhat and
was the source of only one C-class event but
is maintaining an E-type/beta-gamma sunspot group.
NOAA 1564, S15E33, is growing and has produced several
C-class events in the past 24 hours. 1564 is currently classified
as a D-type/beta region but is the brightest H-alpha
plage on the disk. We'll switch to 1564 today. Additional
C-class activity expected.
The position of NOAA 1564 on September 03 at 17:00 UT is:
S15E33 (Solar X = -414", Solar -344")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1560 has increased sunspot count, sunspot
area, and magnetic complexity in the past 24 hours.
1560 has developed a delta configuration located within
the intermediate portion of its E-type/beta-gamma sunspot group.
C-class activity expected with an isolated M-class possible in
the next 24 hour period.
The position of NOAA 1560 on September 02 at 13:00 UT is:
N03W13 (Solar X = 214", Solar Y = -067")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
There was a very impressive filament eruption in the SE quadrant
since the last message. The eruption was associated with a large
double-ribbon flare, a large bright and fast CME and a long-duration
C8.4 x-ray event at 08/31/20:43 UT. Target region, NOAA 1560,
is mostly unchanged maintaining a D-type/beta-gamma sunspot
group. A C-class event is possible in the next 24 hour period.
The position of NOAA 1560 on September 01 at 13:00 UT is:
N04E01 (Solar X = -016", Solar Y = -053")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region now numbered NOAA 1563 was the source of
C-class events in the past 24 hours. 1563 appears to have
decayed after its east limb passage. NOAA regions
1554, N16W75, 1560, N03E12, and the unnumbered region
at S15E76 also produced C-class events. The most interesting
region is NOAA 1560 which has developed a somewhat
magnetically complex D-type/beta-gamma sunspot group.
C-class events probable with an isolated M-class event
possible in the next 24 hour period.
The position of NOAA 1560 on August 31 at 17:00 UT is:
N03E12 (Solar X = -198", Solar Y = -067")
