Dear RHESSI Collaborators,
Solar activity has increased over the past 24 hours with several
C-class flares and an M1.9 flare coming from the target region. The
M1.9 event was a sympathetic flare occurring in NOAA 12422 and NOAA
12423 simultaneously at 10:20 UT today. NOAA 12422 has continued to
increased in size and complexity, and is now classified as a
beta-gamma-delta region due to mixed polarity within the penumbra of
the leader spot. Further intermediate level activity expected with
chance for an additional M-class flare.
The position of NOAA 12422 on 27-Sep-2015 at 14:35 UT is:
S20W12, ( 187", -432" )

Dear RHESSI Collaborators,
Solar activity remains around the low C-level. The target region NOAA
12422 continues to grow and develop as it crosses the central meridian
and is now classified as a beta-gamma/E-type region. Chance remains
for increased activity over the next 24 hours.
The position of NOAA 12422 on 26-Sep-2015 at 14:35 UT is:
S20E01, ( -15", -434" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. The largest event since the last
message was a C3.3 flare at 23:41 UT yesterday from parting region
NOAA 12415. The target region NOAA 12422 has been mostly quiescent but
has continued to increased in size and complexity. There has been some
positive flux emergence around the negative trailing spot. Chance for
some increased activity over the next 24 hours.
The position of NOAA 12422 on 25-Sep-2015 at 12:30 UT is:
S20E17, ( -263", -430" )

Dear RHESSI Collaborators,
Solar activity continues at low levels, with the target region NOAA
12422 producing additional C-level events since the last message,
including a C3.2 flare at 18:54 UT yesterday. The region retains its
beta/D-type configuration and continues to show signs of growth.
Further low-to-intermediate level events possible
The position of NOAA 12422 on 24-Sep-2015 at 11:35 UT is:
S20E29, ( -437", -421" )

Dear RHESSI Collaborators,
Solar activity has remained at very low levels with NOAA 12420
continuing to decay. There were a number of low C-class flares from a
rapidly emerging new region in the southeast quadrant, designated NOAA
12422, which shall be the new target region. The region has a
beta-gamma configuration and may produce further intermediate level
flaring as it develops.
The position of NOAA 12422 on 23-Sep-2015 at 12:30 UT is:
S20E42, ( -602", -407" )

Dear RHESSI Collaborators,
Solar activity has diminished significantly since the last message
with only mid-B-level flares emanating from NOAA 12420. The region
continues to exhibit signs of flux emergence and may be developing a
delta configuration within the leader spot. NOAA 12420 shall continue
to be the target region with intermediate level events possible over
the next 24 hours.
The position of NOAA 12420 on 22-Sep-2015 at 11:35 UT is:
N10E57, ( -791", 101" )

Dear RHESSI Collaborators,
The target region on the northeast limb has been designated as NOAA
12420. It has been classified as a beta-gamma/E-type region and was
the source of several C-class flares since the M1.5 flare yesterday.
The largest event since the last message was an M2.1 flare at 17:32 UT
yesterday from NOAA 12415. NOAA 12420 is showing signs of flux
emergence around its leader spot and shall remain the target region.
Further C-level activity likely with chance for an additional low
M-class flare.
The position of NOAA 12420 on 21-Sep-2015 at 12:30 UT is:
N09E64, ( -849", 97" )

Dear RHESSI Collaborators,
Solar activity has been at a moderate level. An M1.5 event was
produced by a new region (unnumbered yet) just rotating onto the
visible disk at 09/20/04:55 UT. Yesterday's target region NOAA
12415 (S19W50) was the source of three low C-class events in
the previous 24 hours. 12415 remains its beta-gamma/E-type
sunspot group with increasing in spot area slightly. Although 12415
is capable of producing further C-class activities, we will watch the
new region on the east limb today. Additional M-class activity is
probable in the next few days.
The position of the target on September 20 at 16:00 UT is:
N09E83 (Solar X = -920", Solar Y = 150")

Dear RHESSI Collaborators,
Solar activity has returned to a very low level. The largest event
since the last message was a B8.2 at 09/18/21:34 UT produced
by the target region NOAA 12415. 12415 remains classified as a
beta-gamma/E-type sunspot group but decreasing in spot area and
number of spots. It continues to show flux emergence in its leading
portion. B-class activity is expected with a chance of some C-class
activity.
The position of NOAA 12415 on September 19 at 14:35 UT is:
S19W38 (Solar X = 557", Solar Y = -397")

Dear RHESSI Collaborators,
The target region NOAA 12415 has produced 10 C-class flares since
the last message. The largest event was a ~C6 at 09/17/21:12 UT. The
C2 flare at 09/18/04:45 UT was also accompanied by a CME. NOAA
12415 is now classified as a beta-gamma/E-type sunspot group with
increasing in spot area and number of spots. 12415 is showing some
opposite-polarity flux emergence in its leading portion. Further C-class
activity is expected with a chance of an isolated M-class event.
The position of NOAA 12415 on September 18 at 14:35 UT is:
S20W25 (Solar X = 380", Solar Y = -426")
