MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2671 is still slowly developing adding spot count
and area and magnetic complexity. 2671 was the source
of numerous B-class events since the last message.
2671 extended its sunspot group to an F-type group with
a beta-gamma-delta magnetic classification.
The weak delta configuration, located within the intermediate
portion of the region, is currently displaying an absence of bright
H-alpha emission over the umbrae. B-class activity expected,
C-class events probable with a slight chance of an isolated
M-class event in the next 24 hour period.
The position of NOAA 2671 on August 17 at 14:45 UT is:
N11E42 (Solar X = -625", Solar Y = 099")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2671 continues in growth phase
adding sunspot area and sunspot count especially
within its intermediate and trailing portions. 2671 is
currently a large E-type/beta region with some minor
mixed polarities. 2671 was the source of numerous
B-type events in the past 24 hours. B- and C-class
events probable with the slight chance of an isolated
M-class event if growth continues to result in increased
magnetic complexity.
The position of NOAA 2671 on August 16 at 14:45 UT is:
N12E55 (Solar X = -761", Solar Y = 134")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region (now numbered NOAA 2671) produced
numerous minor B- and C-class events since the last
message. The largest was a C2.3 at 08/14/22:10 UT.
2671 is currently displaying dynamic bright H-alpha plage
along with a dark active filament and a beta magnetic
configuration with some minor mixed polarities.
Additional B- and C-class activity probable in the next 24
hour period.
The position of NOAA 2671 on August 15 at 14:45 UT is:
N11E68 (Solar X = -864", Solar Y = 139")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2670 has completed west limb
passage. The target will switch to a new region rotating
over the northeastern limb that was the source of several
minor events since the last message. The largest was
a C2.7 at 08/14/10:46 UT. This region is displaying
dynamic bright H-alpha plage. The region's sunspot group
is too close to the limb to ascertain it's magnetic configuration.
B-class events expected with the chance of another
C-class event in the next 24 hour period.
The approximate position of the target on Aug 14 at 15:00 UT is:
N10E85 (Solar X = -930", Solar Y = 154")

Dear RHESSI Collaborators,
Solar activity continues at very low levels. NOAA 12670 is now on the
western limb and has remained quiescent. It shall continue to be the
target region for a further 24 hours although no activity is expected
before west limb passage.
The position of NOAA 12670 on 13-Aug-2017 at 13:30 UT is:
S07W80, ( 925", -133" )

Dear RHESSI Collaborators,
Quiet-Sun conditions continue. Alpha region NOAA 12670 has remained
quiescent as it approaches the western limb. It shall remain the
target region for a further 24 hours although no increase in activity
is expected.
The position of NOAA 12670 on 12-Aug-2017 at 15:30 UT is:
S07W68, ( 872", -154" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels. NOAA 12670 continues to
decay as it approaches the western limb. It retains its alpha
configuration and shall remain the target region for a further 24
hours. No increase in activity expected at this time.
The position of NOAA 12670 on 11-Aug-2017 at 15:30 UT is:
S07W56, ( 780", -174" )

Dear RHESSI Collaborators,
Solar activity remains at very low levels. The target region NOAA
12670 has showed no signs of change as it traverses the solar disk. It
retains its alpha spot configurations and has begun to show signs of
decay. No increase in solar activity expected over the next 24 hours.
The position of NOAA 12670 on 10-Aug-2017 at 15:30 UT is:
S06W42, ( 631", -176" )

Dear RHESSI Collaborators,
Quiet-Sun conditions continue. NOAA 12670 remains the sole active
region on the visible disk. It retains its positive polarity alpha
spot configuration and has showed no signs of change since the last
message. No increase in activity expected over the next 24 hours.
The position of NOAA 12670 on 9-Aug-2017 at 15:30 UT is:

Dear RHESSI Collaborators,
Solar conditions remain unchanged. NOAA 12670 retains its alpha
configuration and has remained quiescent since the last message. It
shall remain the target region although no change in activity is
expected over the next few days. Include the nearby filaments in your
field of view if possible.
The position of NOAA 12670 on 8-Aug-2017 at 13:30 UT is:
