Dear RHESSI Collaborators,
The level of solar activity is low-to-moderate. A new unnumbered
region is currently rotating over the North East limb and appears
to be a reasonably-sized spot group of at least a beta magnetic
classification, although its proximity to the limb prevents more
accurate complexity determination. NOAA 12434 has shown signs of
growth with increasing in spot area and number of spots over the
past 24 hours. This region has maintained a beta-gamma/D-type
sunspot group designation and now has opposite polarity spots in
close proximity to the North of the leading spot. NOAA 12434 has
continued to produce several low C-class flares since the last
message. Further C-class activity are expected over the next 24
hours, with a good chance for further low M-class events.
The position of NOAA 12434 on 17-Oct-2015 at 12:30 UT is:
S10E27, ( -433", -251" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. NOAA 12434 has increased
in number of spots over the past 24 hours and is now classified
as a beta-gamma/D-type sunspot group. This region has continued
to produce significant numbers of C-class flares since the last
message and two M1.1 events (one on 15-Oct-2015 at 23:27 UT and
the other on 16-Oct-2015 at 06:11 UT). Further C-class activity
is expected over the next 24 hours, with a good chance for more
low M-class flares.
The position of NOAA 12434 on 16-Oct-2015 at 15:00 UT is:
S10E40, ( -607”, -241” )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12434 has grown in spot area
and number of spots over the past 24 hours and is now classified as a
beta-gamma/C-type sunspot group. This region has produced nine C-class
flares since the last message, including the largest event (a C3.6 on
15-Oct-2015 at 13:42 UT). Further C-class activity is expected over
the next 24 hours, with a reasonable chance for an M-class event.
The position of NOAA 12434 on 15-Oct-2015 at 17:30 UT is:
S08E50, ( -735", -196" )

Dear RHESSI Collaborators,
Solar activity is at a low level. Yesterday's target region has now
rotated further on disk and is designated as NOAA 12434. This region
is classified as a beta/C-type sunspot group, although this is based
on a time when some of the region may not have rotated over the limb.
NOAA 12434 has remained the most active of all the visible regions
in terms of flare productivity, being the source of 5 B-class flares
since the last message. Further C-class flares are expected over the
following 24-hour period, with a reasonable chance for an M-class.
The position of NOAA 12434 on 14-Oct-2015 at 14:00 UT is:
S08E66, ( -873", -173" )

Dear RHESSI Collaborators,
Solar activity has been increasing over the past 48 hours due to the
arrival of a new region on the southeastern limb. The region is as-yet
unnumbered and its magnetic configuration is uncertain, but it has
already produced several C-class flares, including a C9.5 flare at
14:05 UT today. This shall be the new target region with further
intermediate level activity expected over the next 24 hours.
The approximate position of the target region on 13-Oct-2015 at 20:35 UT is:
S09E76, ( -924", -173" )

Dear RHESSI Collaborators,
Solar activity continues at a very low level. The largest event was
a B4.3 at 10/11/16:01 UT produced by the target region (seems to
be unnumbered). The target region shows some mixed polarities
in its intermediate portion. We will continue to watch this unnumbered
region today. If possible, also include a new region NOAA 12431
(S17E66) within the field of view. Some low level events are likely
in the next 24 hours.
The approximate position of the target on October 11 at 14:35 UT is:
S22E49 (Solar X = -680", Solar Y = -420")

Dear RHESSI Collaborators,
Solar flare activity remains at a very low level with only two B1
events emanating from the solar disk. NOAA 12430 is currently
the only numbered sunspot region with an alpha/H-type classification.
12430 has been flare quiet since it appears. Today's target will
still be near the southeastern limb (nearby 12430), with a potential
of some B-class events in the next 24 hours.
The approximate position of the target on October 10 at 14:35 UT is:
S22E60 (Solar X = -780", Solar Y = -390")

Dear RHESSI Collaborators,
Solar activity remains at a very low level with the soft X-ray flux flat
at ~B1. Yesterday's target region NOAA 12427 has rotated over the
west limb. There are currently two numbered sunspot regions on the
solar disk, which has been flare quiet. Today's target will be near the
southeastern limb with some loops appearing. Only minor events
expected over the next 24 hours.
The position of the target on October 9 at 14:35 UT is:
S22E75 (Solar X = -895", Solar Y = -370")

Dear RHESSI Collaborators,
Solar activity continues at a very low level. There were only several
low level B-class events produced by the target region NOAA 12427.
12427 has rotated off the northwestern limb with some loops still
visible. It will be the target for a further 24 hours. No significant activity
expected in the next 24 hour period.
The position of NOAA 12427 on October 8 at 14:35 UT is:
N16W91 (Solar X = 922", Solar Y = 264")

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The target region
NOAA 12427 was the source of three B-class flares with the
largest one being a B5.1 at 10/07/07:52 UT. There was a filament
eruption at ~07:30 today near the southwestern limb accompanied
by a CME. NOAA 12427 remains a beta/C-type sunspot group
and is rotating to the west limb. No significant activity expected
in the next 24 hours.
The position of NOAA 12427 on October 7 at 17:35 UT is:
N16W82 (Solar X = 914", Solar Y = 248")
