Dear RHESSI Collaborators,
The level of solar activity is low. The two largest regions on the
visible disk (NOAA regions 12209 and 12216) showed signs of decay
over the past 24 hours, while NOAA 12217 emerged new magnetic flux.
NOAA 12217 remains classified as a simple beta/C-type sunspot group
but displays a small amount of mixed polarity flux with no spots in
its intermediate portion. This region was the only source of C-class
flaring since yesterday’s message and also produced several H-alpha
flares. More C-class activity is expected over the following 24 hour
period, with a small chance for an isolated low M-class event.
The position of NOAA 12217 on 25-Nov-2014 at 13:00 UT is:
S19E46, ( -662”, -335” )

Dear RHESSI Collaborators,
Solar activity is at a low level. Yesterday’s target is designated
as NOAA 12217 after rotating further onto the disk. This region is
classified as a simple beta/C-type sunspot group but has continued
to produce C-class events since yesterday’s message, including the
largest event of the past 24 hours (a C4.1 flare on 24-Nov-2014 at
10:50 UT). Further C-class activity is expected over the following
24 hours, with a small chance for a low M-class event.
The position of NOAA 12217 on 24-Nov-2014 at 18:30 UT is:
S19E58, ( -780”, -331” )

Dear RHESSI Collaborators,
Solar activity continues at the C-level. Both NOAA 12209 and 12216
have been relatively quiet since the last message. A new region on the
southeast limb has produced several occulted, C2 flares over the past
few hours, and shall be the new target region. The region is
unnumbered and its configuration is uncertain, but increased activity
is possible.
The approximate position of the target region on 23-Nov-2014 at 16:35 UT is:
S19E83, ( -913", -319" )

Dear RHESSI Collaborators,
There have been a number of C-level flares over the past 24 hours, the
largest being a C8.1 event at 00:54 UT today from NOAA 12209. The
current target region NOAA 12216 also produced some minor activity,
and has increased in both size and complexity and is now classified as
a beta-delta region. Chance of further increased activity over the
next 24 hours.
The position of NOAA 12216 on 22-Nov-2014 at 16:35 UT is:
S14E44, ( -656", -258" )

Dear RHESSI Collaborators,
Solar X-ray flux has remained steady around the C1 level since the
last message. The target region in the southeast quadrant has now been
designated NOAA 12216 and is classified as a beta/D-type region. The
region has been quiescent since the C7.6 flare yesterday, but Ca XV
maps show enhanced emission coming from the vicinity of the region.
Possibility of isolated low-to-intermediate level events over the next
24 hours.
The position of NOAA 12216 on 21-Nov-2014 at 12:35 UT is:
S13E61, ( -829", -235" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 12209 has remained
quiescent since the M5.7 flare on 16-Nov-2014 and has begun to show
signs of decay. We are therefore ending the Major Flare Watch at this
time. An unnumbered region on the southeast limb was the source of a
C7.6 flare at 06:31 UT today and shall be the new target region. Its
magnetic configuration is unknown at this time but additional
mid-level events may be possible.
The approximate position of the target region on 20-Nov-2014 at 12:35 UT is:
S13E78, ( -925", -226" )

Dear RHESSI Collaborators,
Solar activity has continued at the low C-level since the last
message. NOAA 12209 remains unchanged as it passes the central
meridian. Its large beta-gamma-delta configuration still has the
potential for producing an M5 flare or greater over the next 24-48
hours. Major Flare Watch shall remain in effect.
The position of NOAA 12209 on 19-Nov-2014 at 10:04 UT is:
S13E01, ( -16", -258" )

Dear RHESSI Collaborators,
Solar activity has returned to quiescent levels over the past 24
hours. The target region NOAA 12209 maintains its beta-gamma-delta
configuration and appears to show signs of flux emergence along its
polarity inversion line. The potential still exists for an isolated M5
flare or greater. Major Flare Watch shall remain in effect.
The position of NOAA 12209 on 18-Nov-2014 at 10:04 UT is:
S13E12, ( -197", -259" )

Dear RHESSI Collaborators,
NOAA 12209 was the source of an M5.7 flare at 17:35 UT yesterday. The
region retains its beta-gamma-delta/F-type configuration and a sunspot
area of almost 1000 uH. Chance for additional >M5 flares over the next
24-48 hours, therefore Major Flare Watch shall remain in effect.
The position of NOAA 12209 on 17-Nov-2014 at 10:04 UT is:
S14E25, ( -399", -274" )

Dear RHESSI Collaborators,
Solar activity is at a low-to-moderate level. NOAA region 12209
has maintained a beta-gamma-delta/Fkc sunspot group designation
over the last 24 hours and has produced 5 C-class flares since
yesterday's message, the largest being a C3.9 on 16-Nov-2014 at
07:36 UT. 12209 still retains the potential for flaring above
the M5 level, so the MM#003 Major Flare Watch will continue for
at least the next 24 hours.
The position of NOAA 12209 on 16-Nov-2014 at 16:30 UT is:
S15E36, ( -552", -287" )
