Dear RHESSI Collaborators,
Solar activity remains at a very low level with the soft X-ray
flux flat at ~B2. There are currently 2 numbered sunspot region
on the solar disk, both of which were flare quiet. The target
region NOAA 12598 retains its beta/C-type sunspot group.
It appears to show signs of decay. No notable activities are
expected in the next 24 hours.
The position of NOAA 12598 on October 5 at 14:32 UT is:
N13E21 (-336", 116")

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since
the last message was a B6.1 flare at 03:53 UT today, produced
by the target region NOAA 12598. 12598 has a beta/C-type
sunspot group. It is showing some mixed polarities. B-class
activities are expected with a slight chance of low C-class event.
The position of NOAA 12598 on October 4 at 14:32 UT is:
N13E35 (-537", 127")

Dear RHESSI Collaborators,
Solar activity is at a very low level. Yesterday's target region
has been designated as NOAA 12598 that was the source of
a few low B-class flares. 12598 was classified as a beta magnetic
configuration. It is displaying bright surges in H-alpha images,
and showing emergence of both positive and negative fluxes.
B-class activities are expected with a slight chance of low C-class
flares in the next 24 hours.
The position of NOAA 12598 on October 3 at 20:32 UT is:
N12E46 (-676", 123")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The prominence target located on the southwestern limb
at S25 degrees continues in an active phase but the
target will switch today to the small region located in
the northeastern quadrant. The region has slowly developed
from a single sunspot yesterday to several small spots
with a beta magnetic configuration. There is a slight chance
of minor B-class activity in the next 24 hour period.
The position of the target on October 02 at 10:45 UT is:
N12E66 (Solar X = -858", Solar Y = 154")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2597 has completed west limb passage. The visible
solar disk is displaying only one tiny alpha spot located at
approximately N14E80. The target will be an active
prominence located on the southwestern limb. It is
possible that the prominence will become more destabilized
and erupt in the next 24 hour period.
The position of the target on October 01 at 06:45 UT is:
S26W90 (Solar X = 862", Solar Y = 416")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2597 continues to decay as it rotates over the
southwestern limb. The visible solar disk is currently
almost spotless - there is a tiny plage with a sunspot
pore located at S02E63. No significant flare events
expected anytime soon.
The position of NOAA 2597 on September 30 at 10:30 UT is:
S14W86 (Solar X = 927", Solar Y = -237")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2597 was again the source of B-class events in the
past 24 hour period. The largest was a B7.5 event at
09/28/17:07 UT. 2597 is now decaying especially within
its trailing portion. B-class events possible with a slight
chance of an isolated C-class event in the next 24 hours.
The position of NOAA 2597 on September 29 at 10:30 UT is:
S14W72 (Solar X =884", Solar Y = -264")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2597 is mostly unchanged. The region produced
a few minor B-class events in the past 24 hours. B-class
events probable with the chance of a C-class event in
the next 24 hour period.
The position of NOAA 2597 on September 28 at 10:30 UT is:
S14W58 (Solar X = 789", Solar Y = -289")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2597 was again the source of several B-class events and
a C1.0 event at 09/27/07:48 UT. 2597 has decayed somewhat
within its intermediate portion but increased its penumbral
area in the main leading and trailing sunspots. B-class events
probable with another C-class event possible in the next 24 hour
period.
The position of NOAA 2597 on September 27 at 10:30 UT is:
S14W46 (Solar X = 669", Solar Y = -307")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2597 continues in growth phase adding both sunspot
area and count and is displaying some mixed polarity within
its intermediate and trailing portion. 2597 was the source of
a few minor events since the last message. The largest was
a C1.3 at 09/25/19:14 UT. B-class events probable with the
chance of another C-class event in the next 24 hour period.
The position of NOAA 2597 on September 26 at 10:30 UT is:
