Dear Collaborators,
The target region NOAA 12929 remains a beta/D-type configuration.
It shows mixed polarities in its north portion. If possible, please also
include NOAA 12930 (N20W31) in your field of view, which has a
beta/D-type sunspot group as well. B- and C-class activities are
expected in the next 24 hours.
The position of NOAA 12929 on January 17 at 04:30 UT is:
N08W33 (527", 202")

Dear Collaborators,
The level of solar activity is low-to-moderate. The target region was
confirmed as being numbered as NOAA 12932 with a beta/C-type sunspot
group classification. NOAA 12932 was again the source of two C-class
flares since the last message, but the largest flare of the period
was produced by growing region NOAA 12929 (a C2.6 on 16-Jan-2022 at
20:04 UT) that appears to have developed a delta spot configuration
in addition to its beta/D-type sunspot group classification. 12929
becomes the new target because of its flux emergence over the past
24 hours. C-class activity is expected in the following 24 hours.
The position of NOAA 12929 on 16-Jan-2022 at 21:30 UT is:
N08W32 , ( 512", 203" )

Dear Collaborators,
Solar activity is at a low-to-moderate level. The target region that
was rotating over the North East limb displays a beta magnetic class,
and is expected to be numbered as NOAA 12932 at the start of the next
UT day. This region continued producing several C-class flares since
the last message, which included the largest flare of the period - a
C4.2 flare on 15-Jan-2022 at 08:33 UT. This region will continue as
the target, with C-class flares expected over the next 24 hours and
a chance for another low M-class flare.
The approximate position of this region on 15-Jan-2022 at 20:00 UT is:
N32E63 , ( -738", 546" )

Dear Collaborators,
The level of solar activity is moderate. The target region beyond the
North East limb has begun rotating onto the visible disk with signs of
some leading polarity spots that are extremely foreshortened, so the
region is not capable of being classified yet. This region continued
producing several C-class flares over the past 24 hours as well as a
footpoint-occulted M1.8 flare on 14-Jan-2022 at 01:47 UT. This limb
region will remain as the target, with C-class activity expected in
the following 24-hour period and a chance for a low-to-mid M-class
flare.
The approximate position of this region on 14-Jan-2022 at 20:00 UT is:
N31E90 , ( -836", 500" )

Dear Collaborators,
Solar activity is at a low level. The small flux region that began
emerging spots yesterday has now been designated as NOAA 12928 and
is classed as a beta/D-type sunspot group, but has remained flare
quiet. The target region over the North East limb is now close to
rotating onto the visible disk. This has continued to be the most
flare-active region with producing 2 C-class flares since the last
message, a C1.8 and a C2.9 on 13-Jan-2022 at 01:51 UT and 11:18 UT,
respectively. This limb-crossing location continues as the target
for the next 24 hours, with further C-class activity probable.
The approximate position of this region on 13-Jan-2022 at 20:30 UT is:
N32E90 , ( -827", 515" )

Dear Collaborators,
The level of solar activity is very low. Target region NOAA 12926 was
confirmed as a beta/C-type sunspot group but has remained flare quiet
since the last message. Another small flux region is in the process of
emerging spots in the southern hemisphere close to central meridian,
but has not yet produced any flaring activity. The most flare-active
location has been a limb-occulted region over the North East limb that
was the source of two B-class flares (an impulsive B7.2 on 12-Jan-2022
at 04:13 UT and a CME-associated long-duration B9.1 on 12-Jan-2022 at
04:36 UT). This limb-crossing location will become the new target with
additional B-class activity expected in the next 24 hours and a chance
for C-class flaring.
The approximate position of this region on 12-Jan-2022 at 23:00 UT is:
N32E90 , ( -827", 515" )

Dear Collaborators,
Solar activity is at a very low level. Target NOAA 12924 displayed
an increase in magnetic complexity since yesterday's message and
was classified as a beta-gamma/E-type sunspot group. However, NOAA
12924 appears to have already decreased to a beta configuration.
This region has remained flare quiet while a C1.0 flare occurred
on 11-Jan-2022 at 08:18 UT from a location further East than NOAA
12927. The target instead changes to NOAA 12926 that began the UT
day classified as a spotless H-alpha plage region. 12926 now has a
small leading-polarity spot with a trailing-polarity pore and it
appears to be undergoing emergence of an additional bipole to its
North. A location close to NOAA 12926 was the source of 3 B-class
flares since the last message, the largest being a B7.1 flare on
11-Jan-2022 at 09:14 UT. More B-class flares are expected in the
following 24-hour period, with a chance for a low C-class flare if
NOAA 12926 continues emerging more flux.
The approximate position of NOAA 12926 on 11-Jan-2022 at 23:30 UT is:
N17W36 , ( 550", 341" )

Dear Collaborators,
The level of solar activity is very low. Target region NOAA 12924
has shown signs of slight decay with decreasing in sunspot area
and number of sunspots, but has maintained its classification as
a beta/E-type sunspot group. This region has produced two B-class
flares since the last message, including the largest event of the
period (a B5.5 flare on 9-Jan-2022 at 15:56 UT). Further B-class
activity is expected over the next 24 hours, with a chance for a
C-class flare.
The position of NOAA 12924 on 10-Jan-2022 at 17:00 UT is:
S31W23 , ( 327", -448" )

Dear Collaborators,
Solar activity has reverted to B-level as NOAA 12924 crossed the
central meridian. There has also been a B7.7 flare from a spotless
region close to the northeast limb. NOAA 12924 retains its beta/E-type
configuration and shall continue as the target region for a further 24
hours. Further B-level activity possible with chance for an isolated
C-class flare.
The position of NOAA 12924 on 9-Jan-2022 at 16:30 UT is:
S31W10, ( 145", -445" )

Dear Collaborators,
NOAA 12924 has continued to develop since the last message and was the
source of a C2.7 flare at 22:01 UT yesterday. The region now has a
beta/E-type configuration with an area of almost 500 uh as it
approaches the central meridian. It shall continue as the target
region with further C-level activity expected over the next 24 hours.
Possibility remains for a low M-class flare.
The position of NOAA 12924 on 8-Jan-2022 at 08:30 UT is:
S31E01, ( -14", -447" )
