MM#009 Default Target
Dear Collaborators,
The Target region NOAA 2916 (S17W04, E-type/beta) is
mostly unchanged and was quiescent in the past 24 hours.
The target will switch to NOAA 2918 for the next 24 hour
period. 2918 was the source of several C-class events
and an M1.8 event at 12/28/04:01 UT. The events were
centered on the location of recently emerged opposite
polarity flux within the region's leading polarity portion.
The magnetic class of the region's sunspot group is
now beta-gamma. C-class events likely with the chance
of another M-class event in the next 24 hours.
The position of NOAA 2918 on December 28 at 15:00 UT is:
N21W23 (Solar X = 357", Solar Y = 389")

MM#009 Default Target
Dear Collaborators,
Several minor C-class events were produced by NOAA
regions 2908, 2915, 2916, 2917, and 2920. NOAA 2908
located beyond the southwestern limb was the source
of the largest event (C3.2 at 12/26/20:12 UT). Target region
NOAA 2916 is not as magnetically complex today losing its
beta-gamma-delta configuration but it still has a large
E-type/beta sunspot group with some weak mixed polarities
within its trailing portion. C-class events are possible from
several regions currently located on the visible solar disk.
Target region NOAA 2916 has the potential to produce
C-class events with a slight chance an isolated M-class
event in the next 24 hour period.
The position of NOAA 2916 on December 27 at 15:00 UT is:
S17E09 (Solar X = -147", Solar Y = -246")

Dear Collaborators,
Solar activity has remained at moderate levels with NOAA 12918 in the
northern hemisphere producing a series of low C-class flares. However,
the target region NOAA 12916 has continued to develop and is now
classified as a beta-gamma-delta/E-type region with an area of almost
500uh. The delta spot is at the trailing edge of the region. Despite
remaining quiescent, the region may become more active over the next
24 hours with chance of an M-class flare.
The position of NOAA 12916 on 26-Dec-2021 at 12:30 UT is:
S18E21, ( -333", -266" )

Dear Collaborators,
Solar activity has dropped to the C1 level since the last message with
flares from multiple regions. NOAA 12907 and 12908 have continued to
decay as they transit the western limb. Meanwhile, NOAA 12916 has
increased in size and shows signs of mixed polarities in its trailing
region. NOAA 12916 shall be the new target region with C-level
activity possible over the next 24 hours.
The position of NOAA 12916 on 25-Dec-2021 at 08:30 UT is:
S18E37, ( -560", -273" )

Dear Collaborators,
Solar activity continues at intermediate levels with NOAA 12907 and
12908 continuing to produce C-class flares. The largest event since
the last message was a C7.4 flare from NOAA 12917 at 03:25 UT. NOAA
12907 retains its beta-gamma configuration while NOAA 12908 has
reverted back to a beta region as they both approach the southwest
limb. NOAA 12908 shall remain the target region but also include NOAA
12907 in your field of view if possible. Further C-level activity
likely.
The position of NOAA 12908 on 24-Dec-2021 at 12:30 UT is:
S20W59, ( 787", -316" )

Dear Collaborators,
Solar activity has diminished since the last message. There have been
a number of low C-class flares from the multi-region complex in the
southwest quadrant. NOAA 12908 has now been classified as a beta-gamma
region along with NOAA 12907 as they merge together. Further C-level
activity expected over the next 24 hours with chance for an additional
isolated M-class flare.
The position of NOAA 12908 on 23-Dec-2021 at 12:30 UT is:
S20W46, ( 661", -312" )

Dear Collaborators,
Solar activity remains elevated with twelve numbered active regions
now present on the visible solar disk. NOAA 12908 remains unchanged in
terms of size and complexity and continues to produce C-level activity
as well as an M1.3 flare at 06:54 UT today. The new region now on the
southeast limb has now been designated as NOAA 12916 and has also
produced two M1 flares since the last message. NOAA 12908 shall remain
the target region with further intermediate level activity expected.
Also include NOAA 12907 and 12909 in your field of view if possible.
The position of NOAA 12908 on 22-Dec-2021 at 16:30 UT is:
S20W35, ( 527", -309" )

Dear Collaborators,
Solar activity remains high with M1 flares from the three-region
complex in the southern hemisphere, as well as from a region behind
the southeast limb. NOAA 12907, 12908, and 12909 appear to be in
decay, but NOAA 12907 retains its beta-gamma configuration. NOAA 12908
shall remain the target region with further C- and low M-class
activity likely. Also include NOAA 12907 and 12909 in your field of
view if possible.
The position of NOAA 12908 on 21-Dec-2021 at 16:30 UT is:
S21W21, ( 327", -324" )

Dear Collaborators,
Solar activity has increased significantly since the last message with
NOAA 12907, 12908, and 12909 in the southern hemisphere producing
several C-class flares as well as an M1.8 flare at 11:12 UT today.
NOAA 12908 currently lies along the southern central meridian and is
classified as a beta/E-type region. It shall be the new target region
although please include NOAA 12907 and 12909 in your field of view as
well if possible. Further C-level activity likely with chance for an
additional M-class flare in the next 24 hours.
The position of NOAA 12908 on 20-Dec-2021 at 12:30 UT is:
S21W05, ( 79", -325" )

Dear Collaborators,
Numerous B-class flares were produced by various regions (12907,
12908, 12911) and the largest event, a C6.3 at 12/18/17:27 UT, was
from a limb region (S19E89). The target region NOAA 12911 retains
its beta/C-type configuration and we will watch this region for one more
day. B-class activities are expected and additional C-class flares are
probable, with a slight chance of a low M-class event in the next 24 hours.
The position of NOAA 12911 on December 19 at 04:30 UT is:
N20E36 (-540", 353")
