Dear RHESSI Collaborators,
Solar activity remains at a very low level. NOAA 12415 underwent some
growth in the past 24 hours, but has maintained a beta/D-type sunspot
group classification and produced no notable X-ray flares. Yesterday's
target NOAA 12414 has continued to grow in sunspot area over the past
24 hours. This region maintained its beta-gamma/D-type classification
and was the source of 2 B-class flares (the largest being a B6.4 event
on 13-Sep-2015 at 04:15 UT). More B-class activity is expected, with a
good chance for an isolated C-class flare.
The position of NOAA 12414 on 13-Sep-2015 at 12:30 UT is:
S11W41, ( 615", -270" )

Dear RHESSI Collaborators,
The level of solar activity is low. Newly numbered region NOAA 12415
rotated over the South East limb in the past 24 hours with reasonably
large leading and trailing spot clusters and produced several B-class
flares. Recently emerged NOAA 12414 grew significantly in the past 24
hours, increasing in complexity from an alpha/A-type designation to a
beta-gamma/D-type. NOAA 12414 was the source of the largest flare in
the past 24 hours, a C1.3 on 11-Sep-2015 at 21:30 UT. Further B-class
activity is expected, with a good chance for more C-class flares.
The position of NOAA 12414 on 12-Sep-2015 at 12:30 UT is:
S10W27, ( 426", -271" )

Dear RHESSI Collaborators,
Solar activity remains at an extremely low level. NOAA 12412 decayed
slightly over the previous 24 hours and has remained classified as a
beta/C-type sunspot group. New region NOAA 12414 (alpha/A-type group)
has emerged only 10 degrees ahead of NOAA 12412. B-class activity is
possible over the next 24-hour period.
The position of NOAA 12412 on 10-Sep-2015 at 12:00 UT is:
S08E10, ( -170", -250" )

Dear RHESSI Collaborators,
The level of solar activity is extremely low. NOAA 12412 has shown
some signs of entering decay phase over the past 24 hours, and has
been reclassified as a beta/C-type sunspot group. B-class flaring
is possible over the next 24-hour period.
The position of NOAA 12412 on 9-Sep-2015 at 12:00 UT is:
S07E23, ( -376”, -226” )

Dear RHESSI Collaborators,
Solar activity continues to be very low. NOAA region 12412 has grown
slightly in the past 24 hours and is now classified as a beta/D-type
sunspot group. NOAA 12412 will remain the target region, with B-class
activity possible over the next 24 hours.
The position of NOAA 12412 on 8-Sep-2015 at 12:00 UT is:
S07E37, ( -575", -211" )

Dear RHESSI Collaborators,
The level of solar activity is very low with no flaring activity in
the past 24 hours. The region that rotated over the South East limb
yesterday has been designated as NOAA 12412 and is classified as a
beta/C-type sunspot group. This region appears to be experiencing a
period of weak flux emergence and will become the new target region.
B-class activity is possible over the following 24 hours.
The position of NOAA 12412 on 7-Sep-2015 at 11:00 UT is:
S08E52, ( -744", -205" )

Dear RHESSI Collaborators,
Solar activity remains at very low levels with the GOES soft X-ray
flux at B1 level. There was only a small filament eruption at the
edge of the target region NOAA 12411 at around 09/06/04:30 UT.
NOAA 12411 seems to have a beta magnetic configuration now.
We will watch 12411 for one more day. Only a slight chance for
low C-class activity.
The position of NOAA 12411 on September 6 at 11:35 UT is:
N13E43 (Solar X = (-634", Solar Y = 127")

Dear RHESSI Collaborators,
The GOES soft X-ray flux continues at a B-class level. There were
a few low B-class events emanating from several active regions.
A small filament eruption occurred at ~09/04/18:30 UT around
NOAA 12410, which was associated with a two-ribbon flare and
a weak CME. Yesterday's target region has now designated as
NOAA 12411, with classified as an Alpha/H-type magnetic
configuration (seems too close to the east limb to exactly ascertain
its configuration). NOAA 12411 appears to be the most active
region on the solar disk. B-class activities are expected with a slight
chance of some low C-class activity in the next 24 hour period.
The position of NOAA 12411 on September 5 at 11:35 UT is:
N14E57 (Solar X = (-775", Solar Y = 165")

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The largest event
since the last message was a B4.4 at 09/04/05:13 UT produced
by NOAA 12409 (N03E19). There was a CME at ~09/03/18:00 UT
(seems beyond the southwestern limb). Yesterday's target region
NOAA 12407 has been flare quiet and rotated over the limb. Today
the target will be an unnumbered region, N14E72. This region is
rotating onto the visible disk, and too close to the east limb to
obtain its magnetic configuration. No significant activity is expected
in the next 24 hours.
The position of the target on September 4 at 12:30 UT is:
N14E72 (Solar X = -890", Solar Y = 210")

Dear RHESSI Collaborators,
Solar activity remains at low levels. The largest event in the past 24
hours was a C1.7 limb flare at 09/03/11:28 UT produced by the target
region NOAA 12407. There occurred a CME at ~09/02/14:30 UT (its
source region seems beyond the northwestern limb, and has nothing
to do with the C1.7 flare). We will watch NOAA 12407 for one more
day before it completely rotates over the west limb. Additional occulted
C-class activity might be possible.
The position of NOAA 12407 on September 3 at 12:30 UT is:
N17W91 (Solar X = 909", Solar Y = 277")
