Dear RHESSI Collaborators,
The level of solar activity is low-to-moderate. The target region has
been designated as NOAA 12685. This region has a surprisingly simple
magnetic configuration, classified as an alpha/H-type sunspot group.
NOAA 12685 has produced no flaring activity since the M1.1 event on
20-Oct-2017 at 23:10 UT. The MM#003 Major Flare Watch will remain in
place for the following 24 hours. C-class flares are probable with a
chance for another M-class flare.
The position of NOAA 12685 on 22-Oct-2017 at 18:30 UT is:
S11E64, ( -850", -222" )

Dear RHESSI Collaborators,
The level of solar activity is moderate-to-high. The target region has
rotated its leading spot over the South East limb and produced an M1.1
flare on 20-Oct-2017 at 23:10 UT. This partially limb-occulted event is
from the region previously designated as NOAA 12682 and 12673 that was
the source of significant flare activity on its last two disk passages.
As a result, we are initiating a MM#003 Major Flare Watch (MFW) at this
time. C-class flares are expected over the next 24 hours, with a good
chance for further M-class activity.
The approximate position of this region on 21-Oct-2017 at 10:00 UT is:
S10E88, ( -948", -170" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. The foot points of yesterday's
target region are now rotating into view over the South East limb.
B-class flares are possible in the following 24-hour period.
The approximate position of this region on 20-Oct-2017 at 19:30 UT is:
S10E90, ( -948", -166" )

Dear RHESSI Collaborators,
The level of solar activity is very low. The target will remain with
the expected South East limb location of returning region NOAA 12682
(also previously NOAA 12673). B-class activity is possible over the
next 24 hours.
The approximate position of this region on 19-Oct-2017 at 21:00 UT is:
S10E90, ( -948", -166" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. High-lying loops of the target
region are still only visible above the SE limb. This is likely to be
the return of the region previously numbered as NOAA 12682 (also NOAA
12673) that is approximately 10 degrees behind the limb. This region
produced the only flare since the last message, a B2.4 on 18-Oct-2017
at 08:18 UT that would have been significantly higher magnitude if it
weren’t for occultation by the limb. B-class flares are possible over
the following 24-hour period.
The approximate position of this region on 18-Oct-2017 at 22:30 UT is:
S10E90, ( -948", -166" )

Dear RHESSI Collaborators,
Solar activity has remained at an extremely low level. The target region
will continue to be the anticipated limb-transit location of the region
with high-lying loops that are visible over the SE limb. B-class flares
are possible in the following 24-hour period.
The approximate position of this region on 17-Oct-2017 at 23:00 UT is:
S14E90, ( -933", -232" )

Dear RHESSI Collaborators,
The level of solar activity is extremely low. Yesterday's target region
was designated as NOAA 12684, but produced no flaring activity and has
already decayed to plage. Some high-lying loops are visible over the SE
limb, most likely from the return of the region previously numbered as
NOAA 12681. B-class activity is possible over the next 24 hours.
The approximate position of this region on 16-Oct-2017 at 15:30 UT is:
S14E90, ( -933", -232" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity was at an extremely low level in the
past 24 hours. Yesterday's target filament has mostly
disappeared. There is only a very tiny segment visible
at its northern end. The target will switch to an EFR
located in the northwestern quadrant. B-class activity
possible and if the region continues to develop, there
is a slight chance of a C-class event.
The position of the EFR target on October 15 at 14:30 UT is:
N12W26 (Solar X = 414", Solar Y = 026")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is extremely low. No reportable flare
events for several days. The current visible disk is
spotless. The background x-ray flux is steady at the A4
level. The target filament which is located on the magnetic
inversion line of an old, weak plage remnant has almost
entirely disappeared with only a small dark segment located
on its northern portion. No significant solar flare activity
expected anytime soon.
The position of the filament target on October 14 at 07:15 UT is:
N25W26 (Solar X = 386", Solar Y = 325")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is extremely low. There has been no
reportable flare events since October 9th. The visible
solar disk is spotless. The filament target continues
in an active phase with only a small portion of its northern
segment currently visible. No significant solar flare
activity expected in the next 24 hours.
The position of the target filament on October 13 at 07:30 UT is:
N26E07 (Solar X = -106, Solar Y = 331")
