Dear RHESSI Collaborators,
Solar activity is at a very low level with the X-ray flux flat at B2.
NOAA 12427 is currently the only region with sunspots on the
visible disk. It has decayed to a beta/D-type magnetic configuration.
No significant activity is expected in the next 24 hours.
The position of NOAA 12427 on October 5 at 14:35 UT is:
N18W53 (Solar X = 730", Solar Y = 232")

Dear RHESSI Collaborators,
Solar activity has returned to low levels, with the X-ray flux now
below C-level. Since the last message, NOAA 12422 produced several
C-class flares as well as an M1.0 flare at 02:34 UT today. The region
has rotated off the disk but the looptops remain visible. With no
other viable targets on the visible hemisphere, NOAA 12422 shall
remain the target region for a further 24 hour in case of any last
minute occulted events.
The position of NOAA 12422 on 4-Oct-2015 at 14:35 UT is:
S20W91, ( 900", -323" )

Dear RHESSI Collaborators,
Solar activity has diminished with NOAA 12422 now behind the western
limb. The region is still producing C-class flares and so shall remain
the target region, although we are ending the Major Flare Watch at
this time. Low-to-intermediate level activity is still possible over
the next 24 hours.
The position of NOAA 12422 on 3-Oct-2015 at 12:30 UT is:
S20W90, ( 900", -325" )

Dear RHESSI Collaborators,
Solar activity remains at high levels. The target region, NOAA 12422,
continued to produce C- and M-level events since the last message,
including an M5.5 flare at 00:06 UT today. The region has begun to
rotate off the western limb but remains active. Major Flare watch
shall remain in effect for a further 24 hours due to the possibility
of an >M5 event before west limb passage.
The position of NOAA 12422 on 2-Oct-2015 at 14:35 UT is:
S17W78, ( 896", -300" )

Dear RHESSI Collaborators,
The target region NOAA 12422 was the source of numerous C-class flares
since the last message, as well as an M4.5 flare at 13:03 UT today.
The region appears to be developing an island delta and strong
shearing within its positive leader spot as it approaches the western
limb. Further intermediate level activity expected with chance for
another >M5 event before west limb passage. Major Flare Watch remains
in effect.
The position of NOAA 12422 on 1-Oct-2015 at 14:35 UT is:

Dear RHESSI Collaborators,
Solar activity remains high with numerous C- and M1 flares emanating
from NOAA 12422 since the last message. The target region has
increased in size and extent to an F-type region, and retains the
delta configuration within its leader spot. Further C- and M-level
activity expected with chance for an isolated >M5 flare before it
reaches the western limb. Major Flare Watch campaign shall remain in
effect.
The position of NOAA 12422 on 30-Sep-2015 at 14:35 UT is:

Dear RHESSI Collaborators,
The Sun has remained very active over the past 24 hours. Both NOAA
12422 and NOAA 12423, which are magnetically interconnected, have
continued to produce C- and low-M-class flares. Target region NOAA
12422 retains its delta configuration and is undergoing strong
shearing within its leader spot. Sustained intermediate level activity
is expected with chance of an >M5 level event.
The position of NOAA 12422 on 29-Sep-2015 at 14:35 UT is:
S20W39, ( 567", -409" )

Dear RHESSI Collaborators,
The target region NOAA 12422 has just produced an M7.6 flare beginning
at 14:53 UT today. At this time we are implementing a Major Flare
Watch campaign due to the increased likelihood of further activity at
or above the M5 level over the next 24-48 hours.
The position of NOAA 12422 on 28-Sep-2015 at 14:35 UT is:
S20W25, ( 381", -423" )

Dear RHESSI Collaborators,
Solar activity has continued at intermediate levels over the past 24
hours, with C- and M-level events from both NOAA 12422 and NOAA 12423.
The largest event was an M3.6 flare at 03:34 UT today from NOAA 12423,
which is now nearing the western limb. NOAA 12422 retains its
beta-gamma-delta configuration and has continued to increase in size,
with a current area of 650 uH. Sustained flaring is expected from both
regions with NOAA 12422 remaining the target region.
The position of NOAA 12422 on 28-Sep-2015 at 12:30 UT is:
S20W23, ( 352", -425" )

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" )
