Dear Collaborators,
The level of solar activity is low. Target region NOAA 13599 has
again grew slightly since the last message, but also increased in
magnetic complexity through developing a weak delta configuration
to be classified as a beta-gamma-delta/D-type sunspot group. NOAA
13599 continued to be the most flare-productive region on the disk
by generating six C-class flares in the period, the largest being
a C2.7 on 7-Mar-2024 at 23:48 UT. Additional C-class activity is
expected over the following 24-hour period, with a chance for a
low M-class flare.
The position of NOAA 13599 on 8-Mar-2024 at 12:30 UT is:
S12W09 , ( 147", -82" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13599 grew
further in sunspot area since the last message, but has remained
classified as a beta-gamma/D-type sunspot group. This region has
increased substantially in flare frequency with producing eight
C-class flares in the period, including the largest magnitude (a
C8.3 flare on 7-Mar-2024 at 06:09 UT. Further C-class activity is
expected in the next 24 hours, with a chance for a low M-class
flare.
The position of NOAA 13599 on 7-Mar-2024 at 16:30 UT is:
S12E04 , ( -64", -81" )

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13599 grew
slightly in number of sunspots and spot area since the last message,
including developing polarity mixing of its interior spots to now be
classified as a beta-gamma/D-type sunspot group (making it the most
magnetically complex region). NOAA 13599 has been retrospectively
designated as the source of a C1.5 flare in the period 48-24 hours
ago (on 5-Mar-2024 at 03:58 UT) but has remained flare-quiet since.
Additional C-class flares are expected over the following 24-hour
period.
The position of NOAA 13599 on 6-Mar-2024 at 12:30 UT is:
S13E18 , ( -294", -103" )

Dear Collaborators,
Solar activity is at a low level. The unnumbered target region
has now been designated as NOAA 13602 and was classified as a
beta/D-type sunspot group, but has been flare-quiet since the
last message. NOAA 13599 (a beta/C-type sunspot group) evolved
somewhat in the period in terms of emerging some new flux and
consolidating this into more mature trailing polarity spots.
Despite being flare-quiet, NOAA 13599 becomes the new target
region because it appears to still be emerging magnetic flux.
Further C-class flares are expected in the next 24 hours.
The position of NOAA 13599 on 5-Mar-2024 at 16:30 UT is:
S14E29 , ( -455", -129" )

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13595
continued to decay in number of sunspots and spot area since
the last message, but remains classed as a beta-gamma/E-type
sunspot group. This region has decreased in flare production
but still generated a C1.6 flare on 4-Mar-2024 at 12:00 UT.
The most flare-active region since the last message is a new
flux emergence region in the North East quadrant that has not
yet been numbered by NOAA, being the source of 8 low C-class
flares. This new region has now developed small spots in both
polarities that are expected to persist, so this becomes the
new target region. It is worth noting that the primary bipole
axis is highly inclined towards a North-South orientation.
More C-class flares are expected over the following 24-hour
period.
The approximate position of this region on 4-Mar-2024 at 14:00 UT is:
N19E35 , ( -527", 408" )

Dear Collaborators,
Solar activity remains at a low level. A small number of low C-class
flares were produced since the last message, the largest being a C2.9
from NOAA 13598 at 03:47 UT today. NOAA 13595 remains classified as a
beta-gamma region with an area of 380 μh. NOAA 13595 will continue to
be the target region for the next 24 hours, with a chance for
additional C-class activity.
The position of NOAA 13595 on 3-Mar-2024 at 12:30 UT is:
N20W42, (610",414")

Dear Collaborators,
Solar activity has continued at a low level since the last message.
Several C-class flares were produced, the largest being a C6.6 from
NOAA 13595 at 12:47 UT today. NOAA 13590 has now effectively passed
beyond the solar limb. A region of significant flux in the southeast
quadrant is now numbered as 13599 - this region will be monitored as
it moves further onto the disk. NOAA 13595 is currently classified as
a beta-gamma type region and has increased in area to 370 μh. The
target region will switch to NOAA 13595 for the next 24 hours, with
further C-class activity expected.
The position of NOAA 13595 on 2-Mar-2024 at 12:30 UT is:
N20W30, (456",428")

Dear Collaborators,
Solar activity has continued at a low level since the last message.
Several C-class flares were produced, the largest being a C4.0 from
NOAA 13590 at 01:21 UT today. NOAA 13590 still shows significant flux
as it progresses over the northwest limb. NOAA 13590 will remain the
target region for the next 24 hours while it continues to transit the
solar limb. Further C-class activity is expected.
The position of NOAA 13590 on 1-Mar-2024 at 12:30 UT is:
N18W72, (876",332")

Dear Collaborators,
Solar activity has remained at a low level since the last message. A
small number of flares were produced since the last message, the
largest being an M1.3 from NOAA 13590 at 16:37 UT yesterday. NOAA
13590 remains classified as a beta-gamma-delta region with an area of
930 μh. NOAA 13590 will continue as the target region for the next 24
hours as it begins its transit of the northwest limb. Further C-class
activity is expected with a slight chance for additional isolated
M-class activity.
The position of NOAA 13590 on 29-Feb-2024 at 12:30 UT is:
N18W60, (798",355")

Dear Collaborators,
Solar activity has slightly increased since the last message. Several
C-class flares were produced, the largest being a C5.6 from NOAA 13590
at 11:13 UT today. NOAA 13590 remains classified as a
beta-gamma-delta, however it has further reduced in area and flux over
the last 24 hours and has shown relatively little dynamism in sunspot
behaviour. At this time we are ending the Major Flare Watch. NOAA
13590 will remain the target region for the next 24 hours. Further
C-class activity is expected, with a slight chance for an isolated low
M-class flare.
The position of NOAA 13590 on 28-Feb-2024 at 12:30 UT is:
N18W47, (675",376")
