Dear Collaborators,
The level of solar activity is very low. Target region NOAA
12839 has continued to decay over the past 24 hours and now
is classified as an alpha/A-type sunspot group. This region
has been flare-quiet since yesterday's message and the only
region that produced B-class activity was NOAA 12840. A new
small flux region has rotated over the South East limb and
displays a single spot. This will become the target region
because NOAA 12840 has rotated up to the North East limb.
B-class activity is possible in the next 24 hours.
The approximate position of this region on 8-Jul-2021 at 21:30 UT is:
S19E78 , ( -873", -319" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 12835
produced two low C-class and several B-class flares since
the last message, but has now rotated over the South West
limb. All NOAA regions that remain on disk have continued
to decay since yesterday's message. The target switches to
NOAA 12839 (originally a beta/C-type sunspot group) as it
has maintained several small pores in both of its magnetic
polarities. Additional B-class activity is probable in the
following 24-hour period.
The position of NOAA 12839 on 7-Jul-2021 at 22:00 UT is:
N19W02 , ( 31", 251" )

Dear Collaborators,
The level of solar activity is low. The target plage region that was
previously designated as NOAA 12836 has now rotated beyond the South
West limb. All of the currently NOAA-numbered regions on the visible
disk have shown signs of slight decay since yesterday's message. The
target moves to NOAA 12835 because it produced 3 low-to-mid B-class
flares in the past 24-hour period. Despite slight decay, this region
has maintained its designation as a beta/C-type sunspot group. More
B-class flares are probable over the next 24 hours.
The position of NOAA 12835 on 6-Jul-2021 at 16:30 UT is:
S18W77 , ( 875", -303" )

Dear Collaborators,
Solar activity is currently at a low-to-moderate level. The coronal loops
of NOAA 12838 have fully rotated out of view over the North West limb and
so the Major Flare Watch comes to an end. The small region that emerged
yesterday in the North East quadrant has now been numbered as NOAA 12839
(and designated as a beta/C-type sunspot group), but has been flare-quiet
for more than 24 hours since a C1.3 flare on 4-Jul-2021 at 07:52 UT. NOAA
regions 12835 and 12836 both decayed over the past 24 hours, with 12835
newly designated as a beta/D-type group and 12836 losing its spots to be
classified as plage. Despite having no sunspots, the plage that was NOAA
12836 becomes the target region because it produced the largest flare of
the period (a C1.7 flare on 5-Jul-2021 at 18:37 UT). Larger field-of-view
observations may wish to also include part of the nearby NOAA 12835 due
to it retaining its spots. Additional low C-class activity is possible in
the following 24-hour period.
The approximate position of this region on 5-Jul-2021 at 20:30 UT is:
S26W75 , ( 820", -426" )

Dear Collaborators,
The target limb region has been numbered as NOAA 12838 and
was the source of an X1.5 flare plus two low M-class flares (M1.0
and M1.5) in the past 24 hours. This region has rotated beyond
the west limb with some overlying loops still visible. The Major
Flare Watch will continue for a further 24 hours. There also emerged
a new region (unnumbered yet) in the northeast quadrant which
produced a C1.3 flare. B- and C-class activities are expected with
a chance of additional M-class flare in the next 24 hours.
The position of NOAA 12838 on July 4 at 11:30 UT is:
N24W91 (861", 383")

Dear Collaborators,
Since the message earlier today, the target region on the northwest
limb produced an X1.5 flare at 14:18 UT. At this time we are issuing a
Major Flare Watch. Chance for an additional >M5 flare before the
region transits the western limb.
The approximate position of the target region on 3-Jul-2021 at 11:30 UT is:
N23W80, ( 825", 350" )

Dear Collaborators,
There emerged a new region near the north-west limb, which has
produced two C-class flares (C5.7 and C1.9) as well as an M2.7
flare at 07/03/07:04 UT. We will watch this region today although
it is rotating over the west limb. Yesterday's target NOAA 12835
was designated as a beta-delta/D-type region and produced three
B-class flares since the last message. B- and C-class activities are
expected with a chance of another M flare in the next 24 hours.
The approximate position of the target on July 3 at 11:30 UT is:
N23W80 (825", 350")

Dear Collaborators,
The target region NOAA 12835 was the source of seven B-class flares
in the past 24 hours, the largest one being a B6.1 at 07/01/09:18 UT.
Please note that another region NOAA 12837 (N17E27, beta/B-type)
also produced two B-class flares (B2.8 and B3.1). NOAA 12835 has
been downgraded to a beta-gamma/E-type region. Additional B-class
activities are expected with a good chance of C-class flares in the next
24 hours.
The position of NOAA 12835 on July 2 at 03:30 UT is:
S18W18 (278", -336")

Dear Collaborators,
The target region NOAA 12835 was the source of six B-class flares
as well as two C-class flares (C1.4 and C3.6) in the past 24 hours.
12835 retains its beta-gamma-delta/E-type configuration but still
increases in its sunspot area and number of spots. It continues to
emerge magnetic fluxes in its leading portion. Further C-class activities
are expected with a slight chance of an isolated M-class flare in the
next few days.
The position of NOAA 12835 on July 1 at 03:30 UT is:
S18W03 (47", -337")

Dear Collaborators,
The target region NOAA 12835 was the source of eight B-class flares
in the past 24 hours, the largest one being a B8.6 at 06/29/12:32 UT.
12835 now has been designated as a beta-gamma-delta/E-type region,
increasing in the sunspot area and number of spots. If possible, please
also include 12836 (S28E05) in your field of view. More B-class activities
are expected with a good chance of C-class activities (and a slight chance
of an isolated M-class flare) in the next few days.
The position of NOAA 12835 on June 30 at 03:30 UT is:
