Dear Collaborators,
Solar activity has been at an extremely low level with the
soft X-ray flux below C1. The target region NOAA 13085
was the source of five B-class flares in the past 24 hours,
the largest one being a B5.8 at 08/23/15:32 UT. 13085
remains its beta/D-type configuration but increasing in the
sunspot area and number of spots. It shows some mixed
polarities in its intermediate portion. Only low level activities
are expected in the following 24 hours.
The position of NOAA 13085 on August 24 at 07:30 UT is:
N25W12 (179", 296")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C5.0 flare at 08/22/14:01 UT
emergent from target region NOAA 13085. 13085 was also
the source of five low C-class flares during the period. Some
other regions (NOAA 13084, 13081, and a southeast limb region)
also produced a ~C1 flare from each. Target region 13085
retains its beta/D-type configuration and still shows flux emerging
especially in its trailing portion. Additional C-class activities
are expected in the next 24 hours.
The position of NOAA 13085 on August 23 at 07:30 UT is:

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C2.4 flare at 08/21/23:31 UT
produced by a newly emerged region NOAA 13085. 13085 also
produced another seven ~C1 flares. It has been designated
as a beta/D-type configuration. Today the target will switch to
this region. Yesterday's target NOAA 13078 only produced a
C2.0 flare and now it has rotated beyond the west limb. Further
C-class activities are expected from 13085 in the next 24 hours.
The position of NOAA 13085 on August 22 at 07:30 UT is:

Dear Collaborators,
Solar activity was at a very low level in the past 24 hours.
The largest event of the period was a C2.9 at 08/21/04:48 UT
emergent from NOAA 13081 (N11W54, alpha/H-type). The
target region NOAA 13078 only produced two B-class flares
and has decayed to a beta-gamma/D-type configuration. At
this time we end the Major Flare Watch campaign. 13078 is
rotating over the west limb. We will watch this region for final
24 hours. Only C- and B-class activities are expected in the
next 24 hours.
The position of NOAA 13078 on August 21 at 03:30 UT is:
S24W76 (840", -408")

Dear Collaborators,
The solar activity has decreased since the last message.
The largest event since the last message was a C6.7 flare
at 08/19/20:19 UT produced by target region NOAA 13078.
13078 also produced another five low C-class flares during
the period. This region retains its beta-gamma-delta/D-type
configuration while it seems to decay further. It is showing
magnetic flux cancellations and is rotating to the west limb.
The Major Flare Watch campaign will continue for another
24 hours. Low M-class activities are still likely with a slight
chance of a major flare in the next 24 hours.
The position of NOAA 13078 on August 20 at 03:30 UT is:

Dear Collaborators,
The target region NOAA 13078 produced four low M-class flares
(the largest one being an M1.6 at 08/19/04:14 UT) and also numerous
C-class flares since the last message. 13078 retains its beta-gamma-
delta/D-type configuration, although it appears to enter the decay phase.
This region is showing mixed polarities in its leading and trailing portions.
We will continue the Major Flare Watch campaign today. Further low
M-class flares are expected with a chance of an isolated major flare
in the next few days.
The position of NOAA 13078 on August 19 at 07:30 UT is:

Dear Collaborators,
The target region NOAA 13078 was the source of two low M-class
flares (an M2.0 at 08/17/13:26 UT and an M1.0 at 08/17/14:28 UT)
and three C-class flares since the last message. A few low C-class
flares were also emergent from another two regions NOAA 13081
(N11W10, bata/C-type) and 13082 (N23E35, beta/D-type). 13078
retains its beta-gamma-delta/D-type configuration while decreasing
the sunspot area. It still emerges opposite magnetic fluxes in its core.
Additional low M-class flares are expected with a chance of an isolated
major flare in the next few days.

Dear Collaborators,
The target region NOAA 13078 was the source of an M1.8 flare
(at 08/16/21:10 UT) plus numerous C-class flares in the past 24
hours. 13078 retains its beta-gamma-delta/D-type configuration
with slightly increasing in the sunspot area. The emerging sunspot
region very nearby 13078 has been numbered as NOAA 13083
(S24W33). 13078 continues to emerge new magnetic fluxes.
Further low M-class flares are expected with a chance of major
flares in the next few days.

Dear Collaborators,
Solar activity has been at a moderate level. The target region
NOAA 13078 was the source of eight C-class flares as well as
three M-class flares since the last message, the largest one
being an M5.0 at 08/16/07:52 UT. 13078 has been designated
as a Beta-Gamma-Delta/D-type configuration with increasing
in the sunspot area and number of sunspots. Today we will
implement the Max Millennium coordinated observing plan
#003 (Region Likely To Produce A Major Flare). Additional
low M-class flares are expected with a chance of another major
flare (above M5) in the next few days.

Dear Collaborators,
The largest event since the last message was an M1.0 produced
by NOAA 13078 at 08/15/14:27 UT. 13078 also produced eight
C-class flares. Today the target will switch to 13078 that has a
beta/C-type configuration though. It continues to emerge new fluxes.
Yesterday's target NOAA 13079 produced three low C-class flares
during the period and has decayed to a beta/C-type region. Further
C-class activities are expected with a chance of another low M-class
flare in the next 24 hours.
