Dear RHESSI Collaborators,
The level of solar activity is moderate. Since the previous message,
NOAA 12173 was responsible for an M5.1 flare on 28-Sep-2014 at
2:58 UT. However, the region does not show a strong polarity separation
line or further substantial flux emergence. On the other hand, NOAA
12175 is rapid emerging flux in the following portion, and its delta spot
has strengthened. High C-class activity is expected, with a chance for
an M-class event.
The position of NOAA 12175 on 28-Sep-2014 16:40 UT is:
N15W45, ( 655",168" )

Dear RHESSI Collaborators,
The level of solar activity is low to moderate. Since the
previous message, yesterday's target (NOAA 12172)
released several high C-class events, including a C8.7
flare on 26-Sep-2014 at 05:43 UT. New flux emergence
is evident to the SW of its leading portion. The region
does not show a strong polarity separation line, but exhibits
a gamma configuration. On the other hand, NOAA 12172
(responsible for moderate C-class activity, so far) has
emerged rapidly since the previous message and exhibits
a strong shearing delta configuration, evidenced by the
rapidly moving positive sunspot. High C-class activity
is expected, with a chance for an M-class event.
The position of NOAA 12175 on 26-Sep-2014 19:15 UT is:
N15W23, ( 356", 144" )

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.
The position of NOAA 12172 on 25-Sep-2014 4:45 UT is:
S24E10, ( -346", -269" )

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.
The position of NOAA 12172 on 23-Sep-2014 20:45 UT is:

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.
The position of NOAA 12172 on 22-Sep-2014 23:40 UT is:

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" )
