Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. NOAA 13615 produced over 20 flares in the last 24 hours, the
largest being an M1.9 at 12:55 UT yesterday. NOAA 13615 has grown
slightly since the last message and now has an area of 1140 μh. This
region remains classified as a beta-gamma-delta. NOAA 13615 continues
to show dynamic sunspot behaviour as well as signs of significant
flux. The Major Flare Watch will continue as NOAA 13615 begins its
approach of the southwest limb. Further C- and M-class activity is
likely, with a chance for an isolated >M5 event in the next 24-48
hours.
The position of NOAA 13615 on 27-Mar-2024 at 12:30 UT is:
S13W48, (698",-141")

Dear Collaborators,
Solar activity has continued at an intermediate level since the last
message. NOAA 13615 has produced a substantial number of flares over
the last 24 hours, the largest being an M1.9 at 00:28 UT today. NOAA
13615 has continued to grow in area to 1120 μh and retains its
beta-gamma-delta configuration. Given the size, complexity, and
significant number of events from NOAA 13615, the Major Flare Watch
will continue. Additional C- and M-class activity is expected, with a
chance for an isolated >M5 event in the next 24-48 hours.
The position of NOAA 13615 on 26-Mar-2024 at 12:30 UT is:
S13W34, (525",-123")

Dear Collaborators,
Solar activity has continued at an intermediate level since the last
message. NOAA 13615 has produced 15 flares over the last 24 hours, the
largest being an M4.5 at 06:37 UT today. NOAA 13615 remains classified
as a beta-gamma-delta type region and has further increased in size to
810 μh. The Major Flare Watch will continue with NOAA 13615 as the
target region. Additional >M5 activity is possible over the next 24-48
hours.

Dear Collaborators,
Solar activity has been at a high-to-moderate level.
The largest event since the last message was an M5.4
at 03/23/13:51 UT from the target region NOAA 13615.
13615 also produced more than ten low M-class flares.
It was designated as a beta-gamma-delta/F-type configuration,
with the area being 730 millionths of the solar disk. Further
M-class flares are expected with a good chance of an
X-class flare in the next 24 or 48 hours.
The position of NOAA 13615 on March 24 at 12:30 UT is:
S13W08 (131", -104")

Dear Collaborators,
Solar activity has been at a high level since the last message.
The largest "event" was an X1.1 flare at 00:58 UT today produced
by the target region NOAA 13615 as well as NOAA 13614
(N17W02, beta/D-type)! 13615 also produced four low M-class
flares during the period. It retains a beta-gamma-delta/E-type
configuration, with increasing in the number of spots significantly.
Additional M-class flares are expected with a chance of another
X-class flare in the next one or two days.
The position of NOAA 13615 on March 23 at 08:30 UT is:
S13E05 (-82", -102")

Dear Collaborators,
Solar activity has been at a low level since the last message, with
the largest event being a C8.7 flare at 11:25 UT yesterday produced
by the target region NOAA 13615. 13615 also produced another
five C-class flares during the period. It remains a beta-gamma-delta/
E-type configuration. Today we continue the Major Flare Watch
on this region due to its growing current helicity. Please note that
another region, NOAA 13614 (N17E11), also produced five C-class
flares including a C8.4 at 13:45 UT today, which has a beta/D-type
sunspot group. Further C-class activities are expected, with a chance
of an isolated flare above M5 in the next few days.
The position of NOAA 13615 on March 22 at 16:30 UT is:
S12E15 (-244", -88")

Dear Collaborators,
Solar activity was at a moderate level in the past 24 hours. The
largest event during the period was an M2.0 flare at 22:46 UT
yesterday, produced by the target region NOAA 13615. 13615
also produced ten C-class flares including a C9.0. This region
has been designated as a beta-gamma-delta/E-type configuration,
with increasing the sunspot area but decreasing the number of
spots. It is showing mixed polarities in the intermediate portion.
M-class activities are very likely including an above-M5 flare in
the next one or two days.
The position of NOAA 13615 on March 21 at 08:30 UT is:

Dear Collaborators,
Solar activity continues at a high level. The Major Flare Watch
region NOAA 13615 produced an M7.4 flare at 07:23 UT today
plus an M2.1 flare at 23:17 UT yesterday. It also produced five
C-class flares. This region retains a beta-gamma/E-type configuration
but increases in both the sunspot area and number of spots.
Further low M-class flares are expected with a chance of an
additional major flare (>M5) in the next 24-48 hours.
The position of NOAA 13615 on March 20 at 08:30 UT is:

Dear Collaborators,
Solar activity was at a high level in the past 24 hours. The
largest event was an M6.7 flare at 19:02 UT yesterday
produced by the target region, now numbered as NOAA 13615
that has a beta-gamma/E-type configuration. 13615 also
produced an M1.4 flare at 02:24 UT today and more than ten
C-class flares. At this moment we are implementing the MM#003
Major Flare Watch on this region. Low M-class flares are
expected with a chance of an additional flare above M5 in
the next few days.
The position of NOAA 13615 on March 19 at 12:30 UT is:
S12E55 (-773", -132")

Dear Collaborators,
Solar activity continues at a moderate level. The largest event
since the last message was an M2.8 flare at 03:21 UT today
produced by NOAA 13612 (N22W87) with an Alpha/A-type
configuration. 13612 also produced three ~C5 flares and is now
rotating beyond the west limb. Note that the northeast limb region
mentioned in the two previous messages has been numbered
as NOAA 13614 (N16E63) having an Alpha/H-type sunspot group.
13614 produced an M1.0 flare at 04:06 UT today (plus a C3.1 flare
yesterday). The target region near the southeast limb (unnumbered
yet) generated nine C-class flares, the largest one being a C5.0.
Today we continue to watch this region which has some sunspots
emerging. Further C-class activities are expected with a good
chance of low M-class flares from the target region as well as
NOAA 13614 in the next 24-48 hours.
The approximate position of the target on March 18 at 12:30 UT is:
S13E66 (-860", -180")
