Dear RHESSI Collaborators,
The level of solar activity has decreased again to very low. NOAA 12595
has now completely rotated out of view over the West limb. NOAA 12593
was classified at the beginning of the UT-day as a beta/D-type sunspot
group, but now appears to have some polarity mixing (i.e., beta-gamma)
in its trailing portion. B-class flares are probable over the following
24 hours.
The position of NOAA 12593 on 23-Sep-2016 at 22:00 UT is:
N08W57, ( 798", 70" )

Dear RHESSI Collaborators,
Solar activity has increased since the last message with several
C-class flares - including a C5.6 flare at 05:40 UT today - emanating
from the target region NOAA 12595. The target region is now beyond the
western limb but its looptops remain visible in EUV images. NOAA 12595
shall remain the target region for an additional 24 hours with chance
for another C-level event.
The position of NOAA 12595 on 22-Sep-2016 at 10:30 UT is:
N08W91, ( 946", 134" )

Dear RHESSI Collaborators,
Solar activity has increased since the last message with two C1 flares
emanating from the new target region - NOAA 12595 - today. The region
is now on the western limb and appears to still show signs of growth.
Further low-level activity likely with chance for another C-class
flare before west limb passage.
The position of NOAA 12595 on 21-Sep-2016 at 10:30 UT is:
N11W77, ( 914", 155" )

Dear RHESSI Collaborators,
Solar X-ray flux remains at the low B-level. NOAA 12592 has now
completely decayed, and the newly emerged region NOAA 12593 has begun
to decay. The new target region shall be NOAA 12595, a newly emerged
compact region near the western limb. The region has a large leader
spot with some possible polarity mixing in its core. Chance for some
isolated low level events before west limb passage.
The position of NOAA 12595 on 20-Sep-2016 at 10:30 UT is:
N11W63, ( 837", 128" )

Dear RHESSI Collaborators,
Solar activity remains at the B-level with NOAA 12592 being the source
of a B5.3 flare at 07:32 UT today. A new bipolar region - NOAA 12593 -
has emerged close to disk center but has so far remained quiescent.
The leader spot of NOAA 12592 has decayed completely leaving only a
small trailing spot and an extended plage region. NOAA 12592 shall
remain the target region for a further 24 hours with only minor events
expected.
The position of NOAA 12592 on 19-Sep-2016 at 10:30 UT is:
N14E21, ( -333", 122" )

Dear RHESSI Collaborators,
The target region NOAA 12592 has continued to produce B-level activity
since the last message, including a B6.8 flare at 10:41 UT today. The
region is currently undergoing some renewed flux emergence in its
trailing polarity. Further B-level activity likely with chance for an
isolated low C-class flare.
The position of NOAA 12592 on 18-Sep-2016 at 10:30 UT is:
N14E33, ( -506", 133" )

Dear RHESSI Collaborators,
The target region NOAA 12592 produced several low B-class flares since
the last message, including a B4.0 flare at 05:55 UT today. The region
remains unchanged in terms of size and complexity, but shows some
dynamic behavior in its leading sunspot group. Chance for further
isolated low-level events.
The position of NOAA 12592 on 17-Sep-2016 at 10:30 UT is:
N14E47, ( -679", 150" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. The new target region near the
northeast limb has now been designated as NOAA 12592, and was the
source of a B3.0 flare at 12:00 UT today. The region is mostly
decaying plage except for a few small sunspots near its leading edge.
Chance for further isolated low B-class events.
The position of NOAA 12592 on 16-Sep-2016 at 10:30 UT is:
N14E60, ( -803", 171" )

Dear RHESSI Collaborators,
Solar activity is still at the low B-level. A new, unnumbered active
region rotating onto the northeast limb was the source of two low
B-class flares since the last message. Although the region appears to
comprise of mostly plage, with no discernible sunspots, it shall be
the new target region. Further B-level activity possible.
The approximate position of the target region on 15-Sep-2016 at 20:30 UT is:
N12E72, ( -889", 161" )

Dear RHESSI Collaborators,
Solar activity remains unchanged since the last message. The target
region NOAA 12591 has almost completely decayed and has remained
quiescent. NOAA 12591 shall continue to be the target region for a
further 24 hours although no significant increase in activity is
expected at this time.
The position of NOAA 12591 on 14-Sep-2016 at 20:30 UT is:
N04W36, ( 561", -30" )
