Dear Collaborators,
Solar activity has been at a very low level. No flares have occurred
since the last message. The target region NOAA 12782 has lost its
sunspots and become a plage region. The only region with sunspots
on the visible solar disk now is NOAA 12781 that retains its Alpha/
H-type configuration and is rotating beyond the west limb. Only B-class
activities are likely in the next 24 hours.
The position of NOAA 12782 on November 15 at 08:30 UT is:
S31E20 (-285", -538")

Dear Collaborators,
Solar activity has been at a low level. Only a few B-class
flares occurred since the last message, which were produced
by NOAA 12781. 12781 retains its Alpha/H-type configuration
and is rotating over the west limb. The target region NOAA
12782 has been designated as a beta/C-type region. Additional
B-class activities are expected with a slight chance of a C-class
flare in the next 24 hours.
The position of NOAA 12782 on November 14 at 12:30 UT is:
S31E30 (-416", -536")

Dear Collaborators,
The target region NOAA 12782 was the source of a few low
B-class flares in the past 24 hours. 12782 retains its beta/
C-type configuration. Another spot region NOAA 12781 has
been downgraded to an Alpha/H-type region and flare quiet.
B-class flares are expected with a chance of low C-class flares
in the next 24 hours.
The position of NOAA 12782 on November 13 at 04:30 UT is:

Dear Collaborators,
Yesterday's target region NOAA 12781 has been designated
as a beta/C-type configuration, decreasing its sunspot area and
number of spots significantly. It has been flare quiet mostly since
the last message. Today the target will switch to the limb region
as mentioned in the last two messages. This region has been
numbered as NOAA 12782 with a beta/C-type configuration.
12782 has produced three C-class flares in the past 24 hours,
the largest one being a C2.6 at 11/11/18:36 UT. Additional low
C-class flares are expected in the next 24 hours.
The position of NOAA 12782 on November 12 at 04:30 UT is:
S31E61 (-727", -521")

Dear Collaborators,
The largest event in the past 24 hours was a C1.3 at 11/10/19:36 UT,
produced by the target region NOAA 12781. The east limb region as
mentioned in the last message produced two low B-class flares. NOAA
12781 retains its beta/E-type configuration. It is showing some mixed
polarities in both of its leading and trailing portions. Further B-class flares
are expected with a chance of C-class events in the next 24 hours.
The position of NOAA 12781 on November 11 at 04:30 UT is:
S23W26 (392", -425")

Dear Collaborators,
Solar activity has decreased slightly and only low-level B-class
flares have occurred since the last message. Some of the flares
were produced by a limb region that will rotate onto the visible
disk in the following one or two days. The target region NOAA
12781 also produced two B-class flares. 12781 retains its beta/
E-type configuration but appears to enter its decay phase. Further
B-class flares are expected with a chance of C-class activities
in the next 24 hours.
The position of NOAA 12781 on November 10 at 04:30 UT is:
S23W12 (186", -430")

Dear Collaborators,
The target region NOAA 12781 produced eight B-class flares
in the past 24 hours. 12781 was designated as a beta/E-type
configuration, slightly decreasing its sunspot area but increasing
the number of spots. 12781 continues to show magnetic flux
cancelations. C-class flare activities are probable in the following
24 hours.
The position of NOAA 12781 on November 9 at 04:30 UT is:
S23W00 (0", -433")

Dear Collaborators,
The target region NOAA 12781 produced a few B-class flares
as well as three C-class flares (the largest one being a C5.7 at
05:13 UT on 11/8) in the past 24 hours. 12781 was designated
as a beta-gamma/D-type configuration, decreasing its sunspot
area. It has shown some magnetic flux cancelations. Additional
C-class activities are expected with a slight chance of a low
M-class flare in the next 24 hours.
The position of NOAA 12781 on November 8 at 04:30 UT is:

Dear Collaborators,
There are two regions with sunspots on the visible solar disk,
NOAA 12780 and 12781, the former of which has been flare
quiet. NOAA 12781 is the target region and has produced four
C-class flares and also numerous B-class flares since the last
message. 12781 was classified as a beta-gamma/E-type
configuration, slightly increasing in its sunspot area and number
of spots. It continues showing magnetic flux emergence in its
leading and intermediate portions. Further C-class flares are
expected with a slight chance of a low-level M-class flare in the
following 24 hours.
The position of NOAA 12781 on November 7 at 04:30 UT is:
S23E27 (-405", -430")

Dear Collaborators,
The target region NOAA 12781 produced about ten C-class
flares and also a few B-class flares in the past 24 hours.
12781 was designated as a beta/D-type configuration, slightly
increasing in its spot area. It continues emerging new magnetic
flux, even opposite flux in its leading portion. Further C-class
flares are expected with a slight chance of an M-class flare in
the next 24 hours.
