MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at an extremely low level.
The visible solar disk is spotless. The target filament
has lost almost all of its southern portion and the
northern portion is currently quiescent. No significant
solar flare activity expected in the next 24 hour period.
The position of the filament target on July 22 at 06:30 UT is:
N30E22 (Solar X = -308", Solar Y = 406")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues to be very low. The single
event since the last message was a B1.7 at 07/20/23:15 UT
produced by NOAA 2665 located about 3 days beyond
the southwestern limb. The current background x-ray flux
is flat at the A4 level. The visible solar disk is spotless. The
target filament continues in an active phase. No significant
solar flare activity expected anytime soon.
The position of the target filament on July 21 at 06:30 UT is:
N28 E39 (Solar X = -526", Solar Y =388")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2665 located well beyond the
southwestern limb produced a limb occulted C1.3
event at 07/19/00:01 UT. The current visible disk is
spotless and 2665 is too far beyond the west limb to
continue to be the target. The target will switch to
an active filament located along the magnetic inversion
line of the reversed polarity weak magnetic field of old
NOAA 2664. Solar flare activity is expected to be very
low in the next 24 hour period.
The position of the filament target on July 20 at 05:15 UT is:
N27E53 (Solar X = -674", Solar Y = 386")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2665 has rotated well beyond the southwestern
limb. 2665 was the source of limb occulted minor C-class
events in the past 24 hours. The largest was a C2.8
at 07/19/00:07 UT. It is still possible that 2665 could
produce another interesting limb event in the next 24
hour period. The current visible solar disk is spotless
with only a few decaying plage remnants.
The position of NOAA 2665 on July 19 at 15:30 UT is:
S06W90 (Solar X = 939", Solar Y = -100")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2665 produced several C-class events in the
past 24 hours. The largest was a C2.1 at 07/18/00:40 UT.
2665 is now located almost completely beyond the
southwestern limb but there is a chance of another
minor limb occulted event in the next 24 hour period.
The position of NOAA 2665 on July 18 at 15:30 UT is:
S06W91 (Solar X = 938", Solar Y = -096")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2665 has continued in decay phase losing
almost all of its trailing sunspots. 2665 was the source
of numerous B-class events and two C-class events
since the last message. The largest C-class
event was a C2.3 at 07/17/03:28 UT. B-class activity
probable with the chance of another C-class event
before 2665 completes west limb passage.
The position of NOAA 2665 on July 17 at 15:30 UT is:
S06W79 (Solar X = 921", Solar Y = -112")

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12665 has continued in decay
phase, decreasing in spot area and number of spots to be designated a
beta/D-type sunspot group. 12665 continues to produce C-class flares,
including the largest event of the period (a C5.8 on 15-Jul-2017 at
19:26 UT). More C-class activity is expected over the next 24 hours.
The position of NOAA 12665 on 16-Jul-2017 at 16:30 UT is:
S05W66, ( 861", -112" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 12665 has slowed in decay by
maintaining spot area while decreasing in number of spots. 12665 has
remained designated as a beta/E-type sunspot group and continued to
produce C-class activity, including the largest event since the last
message (a C1.7 on 15-Jul-2017 at 00:20 UT). Further C-class flares
are probable over the following 24-hour period, with a small chance
for a low M-class flare.
The position of NOAA 12665 on 15-Jul-2017 at 11:00 UT is:
S06W49, ( 711", -146" )

Dear RHESSI Collaborators,
The level of solar activity is moderate. NOAA 12665 has shown further
signs of decay with increased number of spots and continued decrease
in area. The target region has remained designated as a beta/E-type
sunspot group by NOAA and produced a long-duration M2.4 flare with a
CME on 14-Jul-2017 at 01:07 UT. C-class flares are expected over the
next 24 hours, with a chance for another low M-class flare.
The position of NOAA 12665 on 14-Jul-2017 at 12:00 UT is:
S07W37, ( 561", -171" )

Dear RHESSI Collaborators,
Solar activity is at a low level. Two newly spotted regions have
emerged in the Northern hemisphere, with only one being numbered
by NOAA as region 12666. This region has remained inactive while
the smaller new, unnumbered spot group (at approximately N13W68)
produced a C8.4 flare on 13-Jul-2017 at 20:01 UT. NOAA 12665 has
again decreased in spot area and magnetic complexity, now being
designated as a beta/E-type sunspot group. NOAA 12665 continued
producing B-class flares and remains the target region. B-class
flares are expected in the following 24-hour period, with a good
chance for additional C-class flares.
The position of NOAA 12665 on 13-Jul-2017 at 21:30 UT is:
S06W29, ( 456", -159" )
