Dear Collaborators,
The level of solar activity is extremely low. Target region NOAA 12857
developed penumbrae on leading and trailing spots to become classified
as a beta/D-type sunspot group at the beginning of the UT day while it
continued to produce A-class activity. However, since then NOAA 12857
has decayed slightly and no longer has any pores/spots present in its
intermediate portion. B-class activity is probable over the following
24-hour period.
The position of NOAA 12857 on 17-Aug-2021 at 20:00 UT is:
N17W38 , ( 559", 192" )

Dear Collaborators,
Solar activity is at a very low level. Target region NOAA 12853 has
decayed further and has shown no signs of flaring activity since the
last message. NOAA 12857 has the most substantial spots on the disk
and is classified as a beta/B-type sunspot group at the start of the
UT day, although it has consolidated some of its intermediate pores
into a spot. NOAA 12857 has been the source of A-class activity and
two B-class flares that were the largest magnitude events since the
last message (a B3.4 flare and a B1.3 flare on 16-Aug-2021 at 07:05
UT and 09:15 UT, respectively). This region becomes the new target,
with B-class activity expected in the next 24 hours.
The position of NOAA 12857 on 16-Aug-2021 at 20:00 UT is:
N18W25 , ( 381", 196" )

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2853 was unchanged with no
noteworthy events during the past 24 hours. The
filament located along the region's main magnetic
inversion line continues to have phases of some activity.
B-class events are possible with only a slight chance
of an isolated C-class event in the next 24 hour period
The position of NOAA 2853 on August 15 at 14:00 UT is:
N25W23 (Solar X = 337", Solar Y =307")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2853 was the source of an isolated
C1.4 event at 08/13/21:08 UT. The filament located along
the region's main magnetic inversion line continues to
sometimes show an active phase. B-class events are
possible with a slight chance of an isolated C-class
event in the next 24 hour period.
The position of NOAA 2853 on August 14 at 13:00 UT is:
N25W10 (Solar X = 149", Solar Y =317")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2853 was the source of a B1.2
event at 08/13/16:23 UT. 2853 has numerous tiny
pores. The filament located along the region's main
magnetic inversion line continues to show an activated
phase. A- and B-class events are possible in the next
24 hour period.
The position of NOAA 2853 on August 13 at 14:00 UT is:
N25E04 (Solar X = -060", Solar Y = 301")

MM#009 Default Target
Dear Collaborators,
The only spot on the visible solar disk today is a
single A-type/alpha located at N13E51. The filament
located along and south of the main magnetic
inversion line in NOAA 2853 was active for several
hours and the southern portion disappeared by
13:30 UT today. The filament may reappear in the
same position after awhile. 2853 was the source
of several minor A-type events and a B1.1 event
at 08/12/04:40 UT. Minor A- and B-class events
possible in the next 24 hour period.
The position of NOAA 2853 on August 12 at 14:00 UT is:
N25E17 (Solar X = -252", Solar Y = 306")

MM#009 Default Target
Dear Collaborators,
The spotless target region NOAA 2853 is mostly unchanged.
It produced only two minor A-class events in the past 24
hour period. Two tiny regions with tiny spots emerged
since the last message. They are located at S22W29
and N13E67. Solar flare activity is expected to
continue at a very low level for the next 24 hours.
The position of NOAA 2853 on August 11 at 14:00 UT is:
N25E31 (Solar X = -444", Solar Y = 316")

MM#009 Default Target
Dear Collaborators,
The visible solar disk is spotless. Target region
NOAA 2853 decayed somewhat losing its tiny spots.
In the past 24 hours 2853 was the source of minor
A-class events and a single B3.0 event at 08/09/18:20 UT.
B-class activity possible with only a slight chance of
an isolated C-class event in the next 24 hour period .
The position of NOAA 2853 on August 10 at 14:00 UT is:
N25E44 (Solar X = -598", Solar Y = 330")

MM#009 Default Target
Dear Collaborators,
The target region is now numbered NOAA 2853. 2853
was the source of numerous minor A- and B-class events
since the last message. It also produced an isolated
C1.3 event at 08/08/00:04 UT. The activity was associated
with an active/eruptive filament located along the region's
main magnetic inversion line and a tiny negative polarity spot
that emerged yesterday within the positive polarity leading
plage. There are a few tiny pores currently visible in both
leading and trailing areas of the region. B-class activity
likely with another C-class event possible in the next
24 hour period.
The position of NOAA 2853 on August 09 at 14:00 UT is:
N25E55 (Solar X = -704", Solar Y = 344")

MM#009 Default Target
Dear Collaborators,
The current visible solar disk is spotless. The
only noteworthy event since the last message
was a limb occulted B5.4 at 08/07/17:01 UT
produced by NOAA 2850 located well beyond
the SW limb at approximately S30. The large
spotless target plage was unchanged and
quiescent in the past 24 hour period. Minor B-class
activity is possible in the next 24 hours.
The position of the target on August 08 at 14:00 UT is:
N26E67 (Solar X = -785", Solar Y = 377")
