Dear RHESSI Collaborators,
Solar flare activity remains at a C-class level. There were a few
low C-class events as well as a C8.7 at 11/23/01:13 UT produced
by NOAA 12454 (N13W62), which developed a beta-gamma
configuration in the past 24 hours. 12454 is rotating to the west
limb. The target region NOAA 12457 only produced several very
low events since the last message. It remains a beta/D-type
configuration with slightly decreasing the sunspot area but increasing
in number of spots. Today we still watch NOAA 12457, with the
potential to produce some low-level C-class activities.
The position of NOAA 12457 on November 23 at 15:35 UT is:
N11E27 (Solar X = -434", Solar Y = 158")

Dear RHESSI Collaborators,
Solar activity has been at GOES C-level since the last message.
There were numerous C-class flares from the target region NOAA
12457 and NOAA 12454 (N13W47), with the largest one being a
C5.6 at 11/22/05:31 UT. 12457 remains its beta/D-type magnetic
configuration with increasing in sunspot area and number of spots
slightly. It continues to display flux emergence and also cancellation
at its southern spots. C-class activities are expected in the next 24
hour period.
The position of NOAA 12457 on November 22 at 15:35 UT is:
N11E40 (Solar X = -614", Solar Y = 160")

Dear RHESSI Collaborators,
Solar activity has increased in the past 24 hours, with a C1.6
event from the target region NOAA 12457 as well as three low-
level C-class events from NOAA 12454 (N12W39; with some
positive flux emerging in the negative leading spot). The target
region 12457 is now classified as a beta/D-type sunspot group
with increasing in sunspot area and number of spots. It continues
to show flux emergence and cancellation in its southern part.
C-class activities are expected from the target region and 12454
in the next 24 hours.
The position of NOAA 12457 on November 21 at 18:35 UT is:
N11E52 (Solar X = -753", Solar Y = 164")

Dear RHESSI Collaborators,
The GOES soft X-ray flux remains below the C-level, with a
few B-class events from the target region, now designated as
NOAA 12457. 12457 is classified as a beta/B-type sunspot
group (may be too close to the limb to exactly obtain its
magnetic configuration). Some C-class flares might be possible
in the next 24 hours.
The position of NOAA 12457 on November 20 at 18:35 UT is:
N12E59 (Solar X = -815", Solar Y = 183")

Dear RHESSI Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C1.1 at 11/18/19:43 UT produced
by yesterday's target region (now its southern part is designated
as NOAA 12456). There is a new region rotating onto the visible
solar disk at the northeastern limb. This unnumbered new region
shows some limb activities, e.g., a B8 at 11/19/07:44 UT. It will be
today's target region with the potential to produce some C-class
events in the next few days.
The position of the target on November 19 at 18:35 UT is:
N18E83 (Solar X = -920", Solar Y = 300")

Dear RHESSI Collaborators,
The GOES soft X-ray flux was at the B-level in the past 24 hours.
The target region NOAA 12454 is now classified as a beta/D-type
configuration with increasing in spot area and number of spots. It is
showing some positive flux emergence in its negative polarity. Only
very low-level activity is possible in the next 24 hour period.
The position of NOAA 12454 on November 18 at 15:35 UT is:
N05E03 (Solar X = -50", Solar Y = 42")

Dear RHESSI Collaborators,
Solar flare activity remains low. The largest event was a C1.1
at 11/17/15:51 UT produced by the target region NOAA 12454.
12454 was also the source of 4 ~B5 flares since the last message.
12454 is showing increased magnetic field strength and mixed
polarities in its southern part, though retaining a beta/B-type
configuration. Low level events are expected in the next 24 hours.
The position of NOAA 12454 on November 17 at 15:35 UT is:
N07E18 (Solar X = -298", Solar Y = 76")

Dear RHESSI Collaborators,
Solar activity continues at a very low level. The largest event was
a B7.8 at 11/15/23:00 UT due to a large filament eruption (S16W24),
which was accompanied by two two-ribbon flares and two CMEs
(seem Earth-directed). Yesterday's target NOAA 12449 was mostly
unchanged and is rotating to the west limb. Today we will watch
NOAA 12454 with a beta/B-type classification. 12454 produced a
B7.3 flare at 11/16/01:27 UT. It is showing mixed polarities in the
intermediate portion. Only low level activity is expected in the next
24 hours.
The position of NOAA 12454 on November 16 at 15:35 UT is:
N10E32 (Solar X = -508", Solar Y = 130")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity remains very low. The largest
event in the past 24 hours was a B5.4 at 11/15/14:25
produced by target region NOAA 2449. The background
x-ray flux is currently at the B2.5 level. 2449 continues
in slow decay phase and all regions on the visible solar
disk are also decaying or are stable. No significant flare
activity expected anytime soon.
The position of NOAA 2449 on November 15 at 12:35 UT is:
S11W43 (Solar X = 651", Solar Y = -220")
