MM#009 Default Target
Dear Collaborators,
Target region NOAA 2900 continued in growth phase
adding sunspot area especially within its trailing portion.
The region's D-type/beta sunspot group has some weak
mixed polarity. 2900 was the source of six B-class events
since the last message. The largest was a B8.4 at
11/28/08:59 UT. NOAA 2898 (24W16) is now decaying
within its intermediate and trailing areas. A- and B-class
events expected with the chance of an isolated C-class
event in the next 24 hour period. Include NOAA 2898,
if possible, within your FOV.
The position of NOAA 2900 on November 28 at 16:30 UT is:
S27W33 (Solar X = 473", Solar Y = -457")

MM#009 Default Target
Dear Collaborators,
The target EFR (NOAA 2900, C-type/beta) was the source
of five B-class events since the last message. The largest
was a B5.1 at 11/27/04:50 UT. NOAA 2898 (S24W04)
produced two B2.4 events. 2900 added sunspot area
and sunspot count in the past 24 hour period. A- and
B-class events expected with the chance of an isolated
C-class event in the next 24 hour period. Include 2898,
if possible, within your FOV.
The position of NOAA 2900 on November 27 at 15:00 UT is:
S28W18 (Solar X =266", Solar Y =-433")

MM#009 Default Target
Dear Collaborators,
NOAA 2898 (S24E10) regained penumbral area
within its trailing area but only produced one A-class
event since the last message. The target will switch
for at least today to a rapidly developing EFR located
about 15 degrees west of 2898. The EFR was the
source of numerous A- and B-class events in the
past 24 hours. The largest event was a B5.0
at 11/26/10:50 UT. The EFR is displaying bright H-alpha
plage and dark arch-type filaments. Include, if possible,
NOAA 2898 within your FOV. A- and B-class events
expected with the chance of a C-class event if the
EFR continues to develop in the next 24 hour period.
The position of the target on November 26 at 15:00 UT is:
S28W05 (Solar X = 075", Solar Y = -450")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2898 was the source of numerous
minor events since the last message. The largest was
a B1.3 event at 11/25/03:42 UT. The region's sunspot
group lost some penumbral area in its trailing sunspots.
The sunspot group classification is now C-class/beta.
Additional A- and B-class events expected with an
isolated C-class event possible in the next 24 hour period.
The position of NOAA 2898 on November 25 at 15:45 UT is:
S24E24 (Solar X = -363", Solar Y = -419")

MM#009 Default Target
Dear Collaborators,
Solar flare activity remains at a very low level. The
recently emerged target region NOAA 2898 was the
source of a few minor events since the last message.
The largest was a B1.3 at 11/24/16:29 UT. 2898
continues in the growth phase adding sunspot area and
spot count. The region's sunspot group classification is
now D-type/beta. Additional minor A- and B-class
events expected with a C-class event possible in the next
24 hour period.
The position of NOAA 2898 on November 24 at 15:45 UT is:
S24E37 (Solar X = -536", Solar Y = -417")

MM#009 Default Target
Dear Collaborators,
Solar flare activity continues at a very low level. The
target region (old NOAA 2891) has completed east limb
passage. It is a large spotless plage. The default
target will switch to an EFR that is currently displaying a
small B-type/beta sunspot group. No significant solar
flare events expected in the next 24 hour period.
The position of the target on November 23 at 15:30 UT is:
S23E52 (Solar X = -707", Solar Y = - 398")

MM#009 Default Target
Dear Collaborators,
Solar flare activity continues at an extremely low level.
Target region NOAA 2897 is mostly unchanged and
quiescent since the last message. It is maintaining
its magnetically simple H-type/alpha sunspot group.
The return of old NOAA 2891 is located just beyond the
northeastern limb at approximately N20 degrees.
2891 was somewhat active during its previous disk
passage but it currently appears to be stable.
We will switch the default target to old NOAA 2891
today. Only minor events expected in the next 24 hours.
The approximate position of the target on Nov. 22 at 15:00 UT is:
N20E89 (Solar X = -913", Solar Y = 332")

Dear Collaborators,
Solar activity has been at a quiet condition with the soft X-ray flux
flat at ~A3 since the last message. At present there are two regions
with sunspots (NOAA 12896 and 12897) on the visible solar disk,
both of which have an Alpha/H-type magnetic configuration. The
target region NOAA 12897 continues to decay and no notable events
are expected in the next 24 hours.
The position of NOAA 12897 on November 21 at 04:30 UT is:
N17E01 (-16", 250")

Dear Collaborators,
Solar activity continues to be very low with the soft X-ray flux
below the B-class level. The target region NOAA 12897 produced
an A4.4 flare (also the largest event) in the past 24 hours. 12897
remains an Alpha/H-type magnetic configuration and enters its decay
phase. No notable events are expected in the following 24 hours.
The position of NOAA 12897 on November 20 at 08:30 UT is:
N16E12 (-194", 233")

Dear Collaborators,
Solar activity has been at an extremely low level. The largest
event since the last message was a B1.5 flare produced by a
south-west limb region. The target region NOAA 12897 only
produced an A-class flare during the period. 12897 remains an
Alpha/H-type configuration with decreasing the sunspot area.
Only very low activities are expected in the next 24 hours.
The position of NOAA 12897 on November 19 at 04:30 UT is:
N17E28 (-437", 250")
