Dear Collaborators,
The target region NOAA 12904 was the source of three A-class
as well as one B1.8 (at 12/07/18:56 UT) flares in the past 24 hours.
12904 retains its beta/B-type magnetic configuration but decreases
the number of spots. It continues to decay and only A- and B-class
activities are expected in the next 24-hour period.
The position of NOAA 12904 on December 8 at 04:30 UT is:
S26E13 (-197", -428")

Dear Collaborators,
NOAA 12898 has completely rotated over the west limb. Today the
target will switch to NOAA 12904, the only region with sunspots on
the visible solar disk at present. 12904 has a beta/D-type configuration
and produced a C1.3 flare at 12/06/06:50 UT and also a B9.6 flare in
the past 24 hours. 12904 appears to enter its decay phase. B-class
activities are probable in the next 24 hours.
The position of NOAA 12904 on December 7 at 04:30 UT is:
S27E26 (-381", -444")

Dear Collaborators,
The target region NOAA 12898 produced a limb-occulted C1.6 flare
since the last message. We will watch this region for a final 24-hour
period. Note that NOAA 12904 (S27E42) has been designated as a
beta/B-type configuration and showed an increase in activity. B-class
flare events are expected in the next 24 hours.
The position of NOAA 12898 on December 6 at 04:30 UT is:
S27W90 (880", -440")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2898 was the source of a limb occulted
M1.4 event at 12/05/07:19 UT. 2898 also produced
numerous occulted C-class events. The largest was a
C7.1 at 12/04/23:59. 2898 is now well beyond the
southwestern limb. We will monitor the limb for at least
the next 24 hour period. The regions on the visible disk
are stable and quiescent. B- and C-class limb occulted
events possible.
The position of NOAA 2898 on December 05 at 13:00 UT is:
S27W89 (Solar X = 868", Solar Y = -442")

MM#009 Default Target
Dear Collaborators,
The target EFR (NOAA 2898) continued in a strong growth
phase during its west limb passage. The EFR was the
source of 8 B-class and 7 C-class events since the last
message. The largest was a C4.2 at 12/04/05:15 UT.
The region is now almost completely beyond the
southwestern limb but it could still produce occulted
C-class activity with even a very slight chance of an
isolated M-class event in the next 24 hour period.
The position of NOAA 2898 on December 04 at 15:00 UT is:
S27W89 (Solar X = 868", Solar y = -442")

MM#009 Default Target
Dear Collaborators,
Target regions NOAA 2900/2898 are now beyond (2900)
and on the west limb (2898). Emerging flux located
in the southern trailing portion of 2898 was the source
of eight B-class events since the last message. The
largest was a B2.8 at 12/03/02:56 UT. The EFR is too
close to the southwestern limb to ascertain its magnetic
classification but it appears to be developing. Additional
B-class events expected with the chance of an isolated
C-class event if the region continues in the growth phase.
The position of the target on December 03 at 15:45 UT is:
S27W77 (Solar X = 846", Solar Y = -444")

MM#009 Default Target
Dear Collaborators,
Target regions NOAA 2900 and 2898 are now rotating
over the southwestern limb. The two regions were the source
of a few minor A- and B-class events in the past 24 hours.
NOAA 2902 increased its magnetic complexity slightly
yesterday with tiny adjacent opposite polarity spots but they
are now decaying losing penumbral area. 2902 produced
seven minor B-class events since the last message.
The default target will continue to be 2900/2898 for today.
Only minor events expected in the next 24 hour period.
The position of NOAA 2900/2898 on December 02 at 15:45 UT is:
S25W75 (Solar X = 853", Solar Y = 292")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2900 continues to decay and only
produced three minor B-class events since the last message.
The largest was a B1.8 at 11/30/22:26 UT. A recently
emerged region (NOAA 2902, N18W13) has a tiny
B-type/beta-gamma sunspot group. 2902 was the source
of three minor B-class events in the past 24 hours. The default
target will remain 2900 and include 2898. 2902 will
become the target tomorrow if it develops additional sunspot
area, spot count and magnetic complexity. A- and B-class
events possible with only a slight chance of an isolated C-class
event in the next 24 hour period.
The position of NOAA 2900/2898 on December 01 at 13:00 UT is:
S25W60 (Solar X = 766", Solar Y = -418")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2900 continues to decay especially
within its intermediate portion of its D-type/beta sunspot
group. 2900 was the source of three minor B-class events
in the past 24 hour period. The largest was a B3.0 at
11/30/00:20 UT. Additional B-class events possible with
only a slight chance of an isolated C-class event in the
next 24 hour period.
The position of NOAA 2900 on November 30 at 15:00 UT is:

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2900 (C-type/beta) is now in the
decay stage. 2900 produced three B-class events
since the last message. The largest was a B5.2
at 11/28/18:26 UT. NOAA 2899 now located beyond
the southwestern limb at S22 was the source of six
limb occulted B-class events. The largest was a B4.6
at 11/29/13:11 UT. NOAA 2898 (S24W29) is decaying
and has been quiescent since the last message.
A- and B-class events expected with a slight chance
of an isolated C-class event in the next 24 hours.
The position of NOAA 2900 on November 29 at 16:30 UT is:
S26W46 (Solar X = 630", Solar Y = -438")
