Dear RHESSI Collaborators,
The level of solar activity is low. A new region currently
rotating over the East limb was responsible for C-class
activity since the previous message. Yesterday's target
has not released further significant activity, but shows
some evidence for flux emergence in its intermediate
portion. Further C-class activity is expected, with a
chance for another M-class event.
The position of NOAA 12172 on 25-Sep-2014 18:00 UT is:
S10E14, ( -230", -276" )

Dear RHESSI Collaborators,
The level of solar activity is low to moderate. A new
emerging region is visible near disk center in the
northern hemisphere, but has not yet produced significant
activity. Since the previous message, yesterday's target
(12172) was responsible for moderate C-class activity and
an M2.3 flare on 23-Sep-2014 at 23:26 UT. There is evidence
for further flux emergence in the intermediate portion of the
region and a minor mixed polarity spot. Moderate C-class
activity is expected, with a chance for further M-class event.

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target (12172)
has continued to release low C-class activity. There is some
evidence for flux emergence in the intermediate portion of the
region. Further low C-class activity is expected, with a chance
for a moderate C-class flare.

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target (12172)
has continued to release low C-class activity. There is some
evidence for flux emergence within the leading portion of the
region. Further low C-class activity is expected, with a chance
for a moderate C-class flare.

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since the
last message was a C5.2 flare from NOAA 12166 at 11:31 UT today. A
large sunspot group, designated NOAA 12172, has rotated onto the
southeast limb and shall be the new target region. It has produced
several low C-class flares over the past 24 hours and appears to have
a beta-gamma configuration. Further low-level activity expected.
The position of NOAA 12172 on 21-Sep-2014 at 15:35 UT is:
S09E66, ( -863", -195" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 12169 has decayed
significantly since the last message. NOAA 12171, a new region on the
southeast limb, was the source of a C3.3 flare at 17:27 UT yesterday
and shall be the new target region. It has a simple beta/D-type
configuration and may produce additional isolated low level events
over the next 24 hours.
The position of NOAA 12171 on 20-Sep-2014 at 11:35 UT is:
S09E58, ( -801", -210" )

Dear RHESSI Collaborators,
Quiet-Sun conditions have returned with X-ray flux below the C1 level
since the last message. NOAA 12169 has been quiescent since the M1.2
flare at 08:37 UT yesterday, but shall remain the target region. The
region maintains its beta/C-type configuration with only minor
activity expected over the next 24 hours.
The position of NOAA 12169 on 19-Sep-2014 at 11:35 UT is:
N05E46, ( -686", 0" )

Dear RHESSI Collaborators,
Solar activity continues at low-to-intermediate levels. Parting active
region NOAA 12158 was the source of a C7.5 flare at 19:26 UT
yesterday. NOAA 12169, which has just rotated on to the eastern limb,
produced a C6.9 flare at 07:02 UT today and shall be the new target
region. It has a simple beta/C-type configuration and is likely to
produce further C-level events with chance for an isolated low M-class
flare.
The position of NOAA 12169 on 18-Sep-2014 at 11:35 UT is:
N05E59, ( -816", 21" )

Dear RHESSI Collaborators,
Solar activity remains at the low C-level, with events emanating from
both NOAA 12158 and 12164 since the last message. NOAA 12158 is now
transiting the western limb and therefore NOAA 12164 shall be the new
target region. The region has a beta/E-type configuration, and has
shown signs of development over the past 24 hours. Further low-level
activity likely.
The position of NOAA 12164 on 17-Sep-2014 at 11:35 UT is:
S13W47, ( 681", -292" )

Dear RHESSI Collaborators,
Solar conditions remain quiescent with X-ray flux steadily below the
C1 level since the last message. The target region, NOAA 12158, was
the source of a C2.2 flare at 18:11 UT yesterday. The region continues
to decay as it nears the western limb but shall remain the target
region, with only minor activity expected over the next 24 hours.
The position of NOAA 12158 on 16-Sep-2014 at 11:35 UT is:
