Dear Collaborators,
The plage region NOAA 12791 (S15W32) was the source of
a few B-class flares since the last message, the largest one
being a B5.8 at 12/11/00:50 UT. In addition, a B5.3 flare was
produced by an east limb region (S21E89). The target region
NOAA 12790 only showed some EUV jets in the past 24 hours.
12790 remains an alpha/H-type configuration and shows a flux
emergence as it is rotating to the west limb. We will watch
12790 for a further 24 hours; if possible, please also …

12791 in your field of view. B-class activities are expected in
the following 24 hours.
The position of NOAA 12790 on December 11 at 08:30 UT is:

Dear Collaborators,
Solar activity continues at a low level. The target region NOAA
12790 and the plage region NOAA 12791 were the sources of
a few A-class as well as low B-class flares in the past 24 hours.
12790 remains its alpha/H-type configuration. It shows some
small EUV jets. B-class events are probable in the next 24 hours.
The position of NOAA 12790 on December 10 at 08:30 UT is:

Dear Collaborators,
Solar activity has been at a low level since the last message. Only two
~B1 flares were produced by NOAA 12791 that has decayed to a plage
region. The only region with sunspots on the visible solar disk is NOAA
12790. 12790 remains its alpha/H-type configuration and has been flare
quiet since the C7.4 flare. B-class flares are probable with a slight chance
of an isolated C-class event in the next 24 hours.
The position of NOAA 12790 on December 9 at 04:30 UT is:

Dear Collaborators,
The target region NOAA 12790 was the source of a C7.4 flare
(at 12/07/15:46 UT) and also two ~B6 flares in the past 24 hours.
The C7.4 flare was associated with an Earth-directed halo CME.
12790 remains its alpha/H-type configuration and continues to
show mixed polarities in its intermediate portion. B-class flares
are expected with a chance of an isolated C-class event in the
following 24 hours.
The position of NOAA 12790 on December 8 at 04:30 UT is:
S22W18 (280", -365")…

Dear Collaborators,
The largest X-ray event was a B8.3 flare (at 23:32 UT on December 6)
since the last message, which was produced by the target region NOAA
12790. NOAA 12791 (beta/B-type) also produced two B-class flares (a
B3.5 and a B3.6 on December 7). 12790 has been designated as an
alpha/H-type region and in its decay phase. We will watch this region for
a further 24 hours. B-class flares are expected in the next 24 hours.

MM#009 Default Target
Dear Collaborators,
Target region 2790 (H-type/alpha) was the source of two
C-class events since the last message. The largest was
a C1.6 at 12/06/13:27 UT. Both events were associated
with the activation/eruption of the very dynamic small
filament located along the region's U-shaped main magnetic
inversion line. B-class events probable with another C-class
event possible in the next 24 hour period.

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2790 was the source of a
long duration C1.6 x-ray event at 12/05/00:38 UT.
The optical flare was associated with an active/eruptive
filament running along the region's U-shaped magnetic
inversion line. 2790 added a few tiny trailing polarity
spots in the past 24 hours. B-class events probable
with a slight chance of another C-class event in the
next 24 hour period.

MM#009 Default Target
Dear Collaborators,
The largest event since the last message was a C1.4 event
at 12/03/23:59 UT produced by target region NOAA 2790.
2790 decayed significantly losing its trailing polarity spots.
2790 is currently displaying an H-type/alpha sunspot group.
B-class events probable with a slight chance of another
C-class event in the next 24 hour period.
The position of NOAA 2790 on December 04 at 15:00 UT is:

MM#009 Default Target
Dear Collaborators,
Target region 2790 has decayed slightly since the last
message. A filament running along and south of the
region's main magnetic inversion line has been active
in the past 24 hours. 2790 was the source of a C1.2
event at 12/03/10:00 UT. NOAA 2786 produced the
largest event (C1.7 at 12/03/01:56 UT) in the past 24
hour period. B- and C-class events possible in the
next 24 hours.

Dear Collaborators,
The target region is now numbered NOAA 2790. 2790
added a few small leading and trailing polarity spots
adjacent to the leader sunspot. 2790 was the source of
only two minor B-class events since the last message but
appears to have a somewhat unstable magnetic configuration.
The largest event in the past 24 hours was a C1.4 event
at 12/01/23:20 UT produced by NOAA 2786. B- and C-class
events possible in the next 24 hour period.
