Dear Collaborators,
Solar activity has returned to very low levels. NOAA 12827 has
remained quiescent since the last message and has reverted back to a
beta/C-type region. An unnumbered region in the southeast quadrant was
the source of some low B-class flares today. NOAA 12827 shall remain
the target region for the next 24 hours with a possibility of some
isolated low-level events.
The position of NOAA 12827 on 2-Jun-2021 at 11:30 UT is:
N11W04, ( 65", 189" )

Dear Collaborators,
The target region NOAA 12827 has continued to produce B-level activity
since the last message as well as a C1.6 flare at 04:27 UT today. The
region has increased in both size and complexity, and is now
classified as a beta-gamma region. Further B- and C-level activity
likely over the next 24 hours as the region crosses the central
meridian.
The position of NOAA 12827 on 1-Jun-2021 at 11:30 UT is:
N12E08, ( -129", 207" )

Dear Collaborators,
Solar activity continues at low levels with NOAA 12824 now beyond the
western limb. The new target region shall be NOAA 12827 in the
northeast quadrant. The region has produced several B-class flares
since the last message, including a B7.7 flare at 05:34 UT today. It
is classified as a beta/C-type region, and is expected to produce
further low-level activity over the next 24 hours with change of an
isolated C-level event.
The position of NOAA 12827 on 31-May-2021 at 11:30 UT is:
N11E22, ( -349", 192" )

Dear Collaborators,
The target region NOAA 12824 was the source of three low B-class
flares since the last message. 12824 has decayed to a beta/C-type
region. It is almost rotating over the west limb. We will watch this region
for a further (maybe final) 24 hours. Please note that there was a newly
emerged region in the northeast quadrant, numbered as NOAA 12827
(N11E42) with a beta/B-type configuration. B-class activities are expected
with a chance of C-class events in the next 24 hours.
The position of NOAA 12824 on May 30 at 03:30 UT is:
N18W81 (889", 294")

Dear Collaborators,
NOAA 12826 produced four low C-class flares plus a few B-class
flares since the last message. 12826 has rotated over the west limb.
Today the target will switch back to NOAA 12824 which produced the
largest event of the period, a C9.4 flare at 05/28 22:19 UT. This C9.4
flare was associated with a prominent CME. 12824 remains its beta/
D-type configuration. Additional C-class flares are probable with a
very slight chance of an M-class flare in the next 24 hours.
The position of NOAA 12824 on May 29 at 07:30 UT is:
N19W72 (851", 313")

Dear Collaborators,
The target region NOAA 12826 was the source of numerous B-class flares
in the past 24 hours, the largest one being a B9.8 at 05/27/07:58 UT. 12826
had a beta/D-type configuration and is rotating over the west limb. We will
watch this region for a further 24 hours. The other region with sunspots on
the visible disk, NOAA 12824 (N20W57), produced two C-class flares in the
past few hours, a C1.0 and a C7.6 (at 05/27/22:54 UT). 12824 was reclassified
as a beta/D-type region. If possible, please also include 12824 in your field
of view. Additional C-class activities are expected with a slight chance of a
low M-class flare in the following 24 hours.
The position of NOAA 12826 on May 28 at 03:30 UT is:

Dear Collaborators,
The target region NOAA 12826 was the source of numerous B- and
C-class events, the largest one being a C3.8 at 05/26/21:17 UT. 12826
has been classified as a beta/D-type region with increasing its sunspot
area significantly. If possible, please also include NOAA 12824 (N20W43,
the previous target) in your field of view. 12824 also produced a C1.6 flare
during the period. Additional C-class activities are expected with a light
chance of a low M-class event in the next 24 hours.
The position of NOAA 12826 on May 27 at 03:30 UT is:

Dear Collaborators,
Yesterday's target NOAA 12824 (N20W29) was downgraded to
a beta/C-type region. It only produced three low B-class flares in
the past 24 hours. Today the target will switch to the newly emerged
region as mentioned in the last message. This region has been
designated as NOAA 12826 with a beta/C-type configuration.
12826 has produced nine B-class flares, the largest one being a
B9.5 at 05:01 UT today. More B-class activities are expected with
a good chance of C-class events in the next 24 hours.
The position of NOAA 12826 on May 26 at 03:30 UT is:
N24W49 (654", 399")

Dear Collaborators,
The target region NOAA 12824 only produced a few low B-class flares
in the past 24 hours. 12824 retains its beta-gamma/C-type magnetic
configuration. It shows mixed polarities in its leading portion. Please
note that there rapidly emerged a new region in the west of 12824,
which appears some spots. B-class flares are expected with a good
chance of C-class flares in the next 24 hours.
The position of NOAA 12824 on May 25 at 07:30 UT is:
N19W17 (262", 331")

Dear Collaborators,
The target region NOAA 12824 has produced only a
C2.2 (at 05/23/17:00 UT) and a few low B-class flares
since the last message. 12824 maintains its beta-gamma/
C-type configuration. It continues to show some dynamic
surges (or small eruptions) in H-alpha images in its leading
portion. Additional C-class flares are expected with a slight
chance of a low M-class event in the next 24 hours.
The position of NOAA 12824 on May 24 at 07:30 UT is:
