Dear Collaborators,
Solar activity has remained low since the last message. NOAA 13590
produced a number of C-class flares, the largest being an C3.5 at
07:14 UT today. NOAA 13590 remains classified as a beta-gamma-delta
type region, however it has reduced in area to 1130 μh. This region
also appears to have shown a reduction in dynamic sunspot behaviour
and flux. Given the sustained complexity of NOAA 13590, the Major
Flare Watch will be extended for what might be a final 24 hours.
C-class activity is expected with a slight chance for isolated >M5
activity.
The position of NOAA 13590 on 27-Feb-2024 at 12:30 UT is:
N18W38, (568",388")

Dear Collaborators,
Solar activity has slightly diminished since the last message. NOAA
13590 produced several flares, the largest being an M2.1 at 16:47 UT
yesterday. NOAA remains classified as a beta-gamma-delta type region
and now has an area of 1450 μh. This region appears to be showing a
reduction in flux and number of associated spots. However, due to the
sustained complexity and substantial area of NOAA 13590, the Major
Flare Watch will be extended for a further 24 hours, with a chance for
isolated >M5 activity.
The position of NOAA 13590 on 26-Feb-2024 at 12:30 UT is:
N18W20, (316",406")

Dear Collaborators,
Solar activity has remained at a moderate level since the last
message. NOAA 13590 produced several C-class flares, the largest being
a C7.9 at 17:39 UT yesterday. NOAA 13590 remains classified as a
beta-gamma-delta type region and has continued to grow in area to 1400
μh. The Major Flare Watch will be extended for a further 24 hours due
to the sustained complexity and continual growth of target region NOAA
13590, with a chance for isolated >M5 activity.
The position of NOAA 13590 on 25-Feb-2024 at 12:30 UT is:

Dear Collaborators,
Solar activity has continued at a moderate level since the last
message. NOAA 13590 produced a significant number of flares, the
largest being and M4.5 at 06:21 UT today. NOAA 13590 has retained its
beta-gamma-delta configuration and has increased in area to 1150 μh.
This region still shows signs of significant flux and dynamic
behaviour. The Major Flare Watch will continue with NOAA 13590 as the
target region, due to the sustained activity and continual growth of
this region. Further >M5 possible is likely over the next 24-48 hours
.

Dear Collaborators,
Solar activity has continued to increase since the last message. NOAA
13590 produced several flares, with the largest being an X6.4 at 22:08
UT yesterday. NOAA 13590 remains classified as a beta-gamma-delta type
region and currently has a sunspot area of 900 μh. This region
continues to show significant flux and dynamic sunspot motion. The
Major Flare Watch will continue with NOAA 13590 as the target region.
Additional >M5 activity is expected over the next 24-48 hours .
The position of NOAA 13590 on 23-Feb-2024 at 12:30 UT is:

Dear Collaborators,
Solar activity has increased since the last message. NOAA 13590
produced an X1.8 flare at 22:52 UT yesterday and an additional X1.7
flare at 06:17 UT today. NOAA 13590 has increased in complexity and
is now classified as a beta-gamma-delta type region. This region
continues to show signs of significant flux and has a substantial area
of 740 μh. At this time we are implementing a Major Flare Watch with
NOAA 13590 as the target region. Further >M5 activity is expected over
the next 24-48 hours .

Dear Collaborators,
Solar activity remains at a low level since the last message. A small
number of C-class flares were produced, the largest being a partially
occulted C4.4 from a currently unnumbered active region over the
southeast limb at 01:55 UT today. NOAA 13590 continues to show an
increase in both size and complexity, and is currently classified as
a beta-gamma type region with a sunspot area of 760 μh. NOAA 13590
will continue to be the target region for the next 24 hours with a
chance of further C-class activity or greater.

Dear Collaborators,
Solar activity has remained at a low level since the last message. A
small number of C-class flares were produced, the largest being a
partially occulted C4.1 from NOAA 13583 at 22:59 UT yesterday. NOAA
13590 is now classified as a beta-type region with a substantial
sunspot area of 530 μh. This region continues to demonstrate signs of
significant flux as it furthers its transit onto the solar disk. NOAA
13590 will continue to be the target region for the next 24 hours.
Further C-class activity is expected, with a slight chance for an
isolated M-class flare.

Dear Collaborators,
Solar activity has remained at a low level since the last message.
NOAA 13583 produced a small number of low C-class flares as it
continues its transit beyond the northwest limb. Newly numbered active
region NOAA 13590 produced several mid-level C-class flares at the
northeast limb, the largest being a C6.8 at 09:34 UT today. NOAA 13590
is currently showing signs of significant flux as it continues its
transit onto the solar disk. The target region will switch to NOAA
13590, with a chance of further C-class activity or greater in the
next 24 hours.

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13583
has grown slightly in sunspot area since the last message and
is now classified as a beta/F-type sunspot group. NOAA 13583
produced four C-class flares in the period, while a region
currently behind the North East limb produced five C-class
flares, and the largest magnitude flare was from NOAA 13584
(a beta/C-type sunspot group) in the form of a C7.9 flare on
17-Feb-2024 at 18:22 UT. The target stays on NOAA 13583 due
to its higher flaring rate, but the North East limb will be
monitored. Additional high C-class flares are probable in
the next 24 hours, with a small chance for an M-class flare.
The position of NOAA 13583 on 18-Feb-2024 at 16:30 UT is:
N09W60 , ( 831" , 209" )
