Dear Collaborators,
The target region NOAA 12773 has lost its sunspots again
and now the visible solar disk becomes spotless again. No
flares have occurred since the last message. 12773 continues
to decay with magnetic cancellation occurring in its intermediate
portion. Only low-level activities are likely in the next 24 hours.
The position of NOAA 12773 on September 27 at 11:30 UT is:
N27E11 (-163", 332")

Dear Collaborators,
The target NOAA 12773 was the source of two B-class flares
as well as a C1.1 flare (at 23:59 UT on September 25) during
the period. At the beginning of the UT day, 12773 was designated
as an Alpha/A-type region, i.e., regaining its sunspots, but now
it appears to have lost them again. 12773 continues to decay
with magnetic cancellation occurring in its intermediate portion.
Additional B-class activities are likely with a slight chance of a
low-level C-class flare in the next 24 hours.
The position of the target on September 26 at 19:30 UT is:
N27E21 (-306", 337")

Dear Collaborators,
NOAA 12773 has lost its sunspots and become a page region.
Now the visible solar disk is spotless again. 12773 has produced
several A- and B-class flares since the last message, with the
largest one being a B3.4. This region has begun to decay. Only
very low-level activities are expected in the next 24 hours.
The approximate position of the target on September 25 at 15:30 UT is:
N28E39 (-533", 367")

Dear Collaborators,
The target region has been designated as NOAA 12773, with a
beta/B-type magnetic configuration. 12773 produced several A-class
flares as well as a B1.3 in the past 24 hours. It continues to emerge
positive magnetic fluxes. More A- and also B-class events are probable
in the next 24 hours.
The approximate position of the target on September 24 at 03:30 UT is:
N28E60 (-732", 395")

Dear Collaborators,
The target region was the source of a few A-class flares in
the past 24 hours. It continues to show EUV jets. As this region
rotates onto the visible solar disk, its total unsigned magnetic flux
and current helicity increase. Further A-class events are expected
and some B-class flares are probable in the next 24 hours.
The approximate position of the target on September 23 at 07:30 UT is:
N27E70 (-750", 430")

Dear Collaborators,
The target limb region has produced a few A- and B-class
X-ray events (the largest one being a B1.7 at 16:34 UT on
September 21) since the last message. This region is still
too close to the limb to ascertain its magnetic configuration.
Further low-level (A- and B-class) activities are expected in
the following 24 hours.
The approximate position of the target on September 22 at 07:30 UT is:
N27E82 (-780", 430")

Dear Collaborators,
Solar activity has increased since the last message. The target
limb region was the source of numerous A-class events as well as
a few B-class flares, with the largest one being a B4.3 at 12:24 UT
today. This region continues rotating onto the visible solar disk. It is
still hard to determine the magnetic configuration. Additional B-class
flares are expected, with a chance of an isolated C-class flare in the
next 24 hours.
The approximate position of the target on September 21 at 12:00 UT is:
N28E86 (-790", 430")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was an A1.5 (at 23:28 UT yesterday)
produced by an east-limb region, which will be today's target.
This region is rotating onto the visible solar disk. Only minor
(A-class) events are likely in the next 24 hours.
The approximate position of the target on September 20 at 09:00 UT is:
N32E90 (-800", 500")

Dear Collaborators,
Solar activity continues at a background level. The visible
solar disk remains spotless. The small target region is still
bright in EUV passbands. No flaring activity is expected in
the next 24 hours.
The approximate position of the target on September 19 at 15:00 UT is:
S22W16 (250", -450")

Dear Collaborators,
Solar activity continues at a background level. The visible
solar disk remains spotless. Today the target will be an
EUV-bright region which is crossing the central meridian.
No noteworthy activity is expected in the next 24 hours.
The approximate position of the target on September 18 at 15:00 UT is:
S22W00 (0", -450")
