Dear Collaborators,
Solar activity continues at a high level. The largest event
in the past 24 hours was an X3.5 flare at 08:18 UT on
May 15 produced by yesterday's limb target NOAA 13664.
13664 also produced an M3.6 and a C9.9 flares when it
was beyond the west limb. Today we will continue the Major
Flare Watch campaign but the target switches to a southeast
limb region (unnumbered yet) that has produced an X3.0 flare
at 14:20 UT on May 15 plus two M3 flares. M-class activities
are expected with a chance of some X-class flare in the
next 24-48 hours.
The approximate position of the target on May 15 at 23:30 UT is:
S12E86 (-900", -200")

Dear Collaborators,
Solar activity was at a high level in the past 24 hours. The
largest event since the last message was an occulted X8.7
flare at 16:46 UT on May 14 produced by the target limb
region NOAA 13664. This X8.7 is also the largest event in
the solar cycle 25 so far. Besides, 13664 produced another
X1.7 and X1.2 flares plus numerous M-class flares. Today
we will continue the Major Flare Watch campaign for one
more day. Please note that some other regions also produced
several M-class flares, e.g., an M1.1 from 13674 (beta/C-type),
an M4.5 from 13680 (beta/D-type), an M1.3 from 13679
(beta-gamma/D-type). M-class flares are very likely though
from various regions in the next 24 hours.
The position of NOAA 13664 on May 14 at 23:30 UT is:

Dear Collaborators,
Solar activity has been at a high-to-moderate level. The largest event
since the last message was an X1.0 flare at 16:11 UT on May 12 from
the target region NOAA 13664. 13664 also produced more than ten
M-class flares including an M6.7 flare at 09:36 UT on May 13. Today
we will continue the Major Flare Watch campaign on this region when
it is rotating over the west limb. Further M-class flares are expected
with a chance of an occulted major (>M5) flare in the next 24 hours.
The position of NOAA 13664 on May 13 at 23:30 UT is:

Dear Collaborators,
Solar activity has partially diminished since the last message.
However, several significant flares were produced, the largest being
an X1.5 from NOAA 13664 at 11:15 UT yesterday. NOAA 13664 has begun
its transit of the southwest limb and is still showing signs of
significant magnetic flux. The Major Flare Watch will continue with
NOAA 13664 as the target region. Further M-class activity is likely
with a chance for an additional isolated >M5 flare in the next 24
hours.
The position of NOAA 13664 on 12-May-2024 at 11:30 UT is:
S18W69, (844",-276")

Dear Collaborators,
Solar activity remains at a high level. NOAA 13664 produced a number
of substantial flares in the last 24 hours, the largest being an X5.8
at 01:10 UT today. NOAA 13664 has grown significantly to reach an
approximate size of 2400 μh. The Major Flare Watch will continue with
NOAA 13664 as the target region as it begins to approach the southwest
limb. Additional M-class activity is expected, with a chance for
further >M5 flares in the next 24 hours.
The position of NOAA 13664 on 11-May-2024 at 07:30 UT is:

Dear Collaborators,
Solar activity persists at a high level. NOAA 13664 has produced
several significant flares, the largest being an X4.0 at 06:27 UT
today. This region continues to show significant signatures of
magnetic flux and dynamic sunspot behaviour. The Major Flare Watch
will continue with NOAA 13664 as the target region. Additional M-class
activity is expected with a good chance for further >M5 flares in the
next 24 hours.
The position of NOAA 13664 on 10-May-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity continues at a high level. NOAA 13664 produced numerous
M- and X-class flares over the last 24 hours, the largest being an
X2.3 at 08:45 UT today. NOAA 13664 has grown substantially in area,
reaching 1200 μh, and has a substantial associated flux. The Major
Flare Watch will continue with NOAA 13664 as the target region.
Further M-class activity is expected, with a good chance for
additional >M5 flares in the next 24-48 hours.
The position of NOAA 13664 on 09-May-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has reached a high level. Both NOAA 13663 and NOAA
13664 produced a number of significant magnitude flares, each
producing separate X1.0 flares at 01:48 UT today and 04:37 UT today,
respectively. NOAA 13663 has shown a slight decay in area as it
undergoes its transit of the northwest limb. NOAA 13664 has further
grown to an area of 630 μh and has produced a greater number of
significant flares since the last message. The Major Flare Watch will
continue and the target region will now switch to NOAA 13664, however
attention should still be paid to NOAA 13663 for potential limb
flares. Additional M-class activity is expected, with a good chance
for further >M5 activity in the next 24 hours.
The position of NOAA 13664 on 08-May-2024 at 11:30 UT is:
S20W16, (247",-275")

Dear Collaborators,
Solar activity has continued at an elevated level since the last
message. Multiple flares were produced in the last 24 hours, the
largest being an M5.2 from NOAA 13663 at 05:58 UT today. NOAA 13663
remains the most productive active region as it begins its approach of
the northwest limb. An additional active region, NOAA 13664, has
developed into a beta-gamma-delta region and shows signs of
significant flux - this region should be monitored closely over the
next 24 hours. NOAA 13663 will remain the target region at this time
and the Major Flare Watch will continue. Additional M-class activity
is likely in the next 24 hours, with a chance for an additional
isolated >M5 flare.
The position of NOAA 13663 on 07-May-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity remains at an elevated level. NOAA 13663 has produced a
significant number of flares, the largest being an X4.5 at 05:38 UT
today. NOAA 13663 continues to show signs of substantial flux and
sunspot dynamism. The Major Flare Watch will continue with NOAA 13663
as the target region. Further M-class activity is expected, with a
chance for further >M5 activity in the next 24-48 hours.
