Dear Collaborators,
Solar activity remains unchanged since the last message. The decaying,
spotless active region in the northeast quadrant has remained
quiescent, but shall continue to be the target region. Chance for some
isolated A-level activity over the next 24 hours.
The approximate position of the target region on 26-Aug-2020 at 11:00 UT is:
N25E76, ( -837", 373" )

Dear Collaborators,
The new region on the northeastern limb has rotated into view but has
not resulted in any increased activity since the last message. Its
magnetic configuration is uncertain at this time but it shall continue
to be the target region, with no significant change in activity levels
expected over the next 24 hours.
The approximate position of the target region on 25-Aug-2020 at 11:00 UT is:
N30E88 = (-821", 467")

Dear Collaborators,
Solar activity remains at extremely low levels with the visible solar
disk remaining spotless. STEREO-A images suggest that a small compact
region could rotate over the northeast limb in the coming days. This
potential region shall continue to be the target for the next 24 hours
although no increase in activity is expected at this time.
The approximate position of the target region on 24-Aug-2020 at 11:00 UT is:
N30E89, ( -822", 470" )

Dear Collaborators,
Solar activity has been at a very low level with the visible solar disk
being spotless. Only an A1.9 flare was produced by NOAA 12772
that is rotating over the west limb. Yesterday's target region has been
further decaying and has not produced any events since the last
message. Today the target will switch to an east-limb region that will
be rotating onto the visible disk. Only minor activities are possible in
the next 24 hours.
The approximate position of the target on August 23 at 10:00 UT is:
N32E87 (-880", 480")

Dear Collaborators,
The largest X-ray event since the last message was an A6.1
at 14:42 UT on August 22, produced by the unnumbered target
region. A few lower level A-class events were also produced
by NOAA 12772 that is rotating over the west limb. The target
region appears to be decaying. Only minor activities are likely
in the next 24 hours.
The approximate position of the target on August 22 at 19:00 UT is:
S31E30 (-390", -560")

Dear Collaborators,
Yesterday's target region NOAA 12772 only produced an A2.1 flare
in the past 24 hours. This region has been classified as a beta/B-type
configuration, slightly decreasing in the sunspot area and number of
spots. Today the target will switch to a plage region in the southeast
quadrant, which was the source of several A-class events as well as
a B1.6 flare (at 01:58 UT today). Further A-class activities are possible
with a chance of a B-class event in the next 24 hours.
The approximate position of the target on August 21 at 11:00 UT is:
S31E48 (-590", -520")

Dear Collaborators,
The target region NOAA 12772 produced several A-class flares
as well as two B-class flares (with the largest one being a B3.9
at 22:36 UT on August 19) in the past 24 hours. 12772 has been
classified as a beta/C-type region, increasing in the sunspot area
and number of spots. Additional B-class activities are likely in the
next 24 hours.
The position of NOAA 12772 on August 20 at 06:55 UT is:
N18W51 (702", 223")

Dear Collaborators,
The target region has been designated as NOAA 12772
which has a beta/B-type configuration. This region was
the source of numerous A-class events as well as an isolated
B2.5 flare in the past 24 hours. It continues to show flux
emergence and also cancellation. Further B-class activities
are possible in the following 24 hours.
The position of NOAA 12772 on August 19 at 01:00 UT is:
N18W37 (544", 205")

Dear Collaborators,
Solar activity has been at a very low level for the past 24 hours.
Yesterday's target has been quiet and begun its decay phase.
Today the target will switch to a new emerging flux region in the
northwest quadrant. This region has produced two ~A1.5 X-ray
events and emerged some bipolar sunspots (should be numbered
as NOAA 12772 tomorrow). Additional A-class events are expected
with a chance of B-class events in the next 24 hours.
The approximate position of the target on August 18 at 09:30 UT is:
N17W28 (400", 190")

Dear Collaborators,
The target spotless region produced a ~B1.2 two-ribbon flare
at 17:12 UT yesterday, which was associated with a filament
eruption and accompanied by a CME. We will continue watching
this region today as a filament reappears in this region. There
was another ~B1.0 flare produced by NOAA 12770 that only
shows some overlying loops above the northwest limb. Very
low-level activities are possible in the next 24 hours.
The approximate position of the target on August 17 at 09:00 UT is:
S32E16 (-240", -580")
