Dear Collaborators,
Solar activity remains at a low level. Several flares have been produced
since the last message, the largest being a C7.4 from NOAA 14420 at 15:24
UT yesterday. NOAA 14420 is now close to transiting fully beyond the
northwestern limb, however it has still produced some partially occulted
flares since the last message. Newly numbered active region NOAA 14431 has
moved onto the disk from the southeastern limb, this region has shown
notable signs of sunspot dynamism since coming into view. The target region
will switch to NOAA 14431, however while still possible, attention should
be paid to the limb location of NOAA 14420 for the chance of some final
occulted events. Additional C-class activity is expected in the next 24
hours.
The position of NOAA 14431 on 02-May-2026 at 03:30 UT is:
N16E51, (-712", -221")

Dear Collaborators,
Solar activity continues steadily at a low level. NOAA 14420 a small number
of flares since the last message, the largest being a pair of C1.9 flares
at 04:12 and 09:29 UT today, respectively . NOAA 14420 is now transiting
the northwestern limb and still shows signs of strong flux. This region
will remain the target region while it is still in view. Further C-class
activity is expected.
The position of NOAA 14420 on 01-May-2026 at 11:30 UT is:
N16W76, (888", 277")

Dear Collaborators,
Solar activity is at a low level. Several flares were produced since the
last message, the largest being a C3.7 from a currently unnumbered active
region over the southeastern limb at 09:35 UT today. NOAA 14420 continues
to produce multiple flares, however in the last 24 hours these have been
limited to lower C-class flares. This region is now beginning to transit
the northwestern limb, signs of emerging flux still exist in this region
and it should continue to be monitored. NOAA 14420 will remain the target
region. Further C-class activity is expected.
The position of NOAA 14420 on 30-April-2026 at 11:30 UT is:

Dear Collaborators,
Solar activity remains at a low-moderate level. A number of flares were
produced in the last 24 hours, including a trio of M-class events, the
largest being an M1.6 from NOAA 14420 at 13:49 UT yesterday. NOAA 14420
produced fifteen flares since the last message, and while the flux
associated with the region appears to have reduced slightly, the region
still shows notable sunspot activity. At this time, we are ending the Major
Flare Watch, however NOAA 14420 will remain as the target region. Further
C-class and low M-class activity is likely in the next 24 hours.
The position of NOAA 14420 on 29-April-2026 at 07:30 UT is:

Dear Collaborators,
Solar activity continues at a low-moderate level. Several flares were
produced since the last message, the largest being a C9.0 from NOAA 14420
at 09:14 UT today. NOAA 14420 has seen a partial reduction in the levels of
sunspot dynamism since the last message, however this region still shows
significant flux. Meanwhile, NOAA 14425 has doubled in size over the last
24 hours but has not produced any particularly significant flares. The
Major Flare Watch will remain active for a final 24 hours with NOAA 14420
as the primary target region. Additional attention should be paid to the
development of NOAA 14425 also. Further mid-high C-class activity is
anticipated with the very slight chance for a >M5.0 event.
The position of NOAA 14420 on 28-April-2026 at 11:30 UT is:

Dear Collaborators,
Solar activity remains at a low-moderate level. NOAA 14420 was the site of
numerous flares in the last 24 hours including an M6.0 at 22:51 UT
yesterday. NOAA 14419 has now passed beyond the northwestern limb.
Meanwhile, NOAA 14420 continues to develop, it retains its beta-gamma-delta
type configuration while showing significant levels of flux. Additionally,
NOAA 14425 has developed into a beta-gamma-delta region, though this region
is not quite as large as NOAA 14420. Due to the continued production of
large flares, the Major Flare Watch will be extended with NOAA 14420 as the
target region. Additional high C-class and low M-class activity is likely,
with the chance for a further isolated >M5.0 flare.
The position of NOAA 14420 on 27-April-2026 at 11:30 UT is:

Dear Collaborators,
Solar activity is at a low-moderate level. Several flares were produced in
the last 24 hours, the largest being an M1.4 from an unnumbered region in
close proximity (and possibly associated with) NOAA 14420 at 13:54 UT
today. NOAA 14419 and NOAA 14420 have been relatively quiet since the last
message. NOAA 14419 is almost out of view over the northwestern limb. NOAA
14420 shows significant flux and retains its beta-gamma-delta
configuration. The Major Flare Watch will be extended for what may be the
final 24 hours with NOAA 14420 as the primary target region. Additional
attention should also be paid to NOAA 14419 as this region may produce
occulted events as it passes out of view. Further C-class activity and low
M-class activity is expected with a small chance for an isolated >M5.0
event.
The position of NOAA 14420 on 26-April-2026 at 11:30 UT is:

Dear Collaborators,
Solar activity remains at an intermediate level. Several flares were
produced since the last message, the largest being an M6.4 from NOAA 14419
at 17:15 UT yesterday. Both NOAA 14419 and 14420 retain their
beta-gamma-delta configuration, though NOAA 14419 is now situated at the
northwestern limb and continuing its transition beyond. The Major Flare
Watch will remain active with NOAA 14419 as the target region, however,
additional attention should also be paid to NOAA 14420. Further high
C-class and mid-low M-class activity is likely with the chance for
additional (potentially partially occulted) >M5.0 events in the next 24-48
hours.
The position of NOAA 14419 on 25-April-2026 at 15:30 UT is:

Dear Collaborators,
Solar activity has further increased. NOAA 14419 was the site of two
X-class flares since the last message. These flares were an X2.4 and X2.5
occurring at 00:51 UT and 08:01 UT today, respectively. Additionally, NOAA
14419 and NOAA 14420 have both been upgraded to beta-gamma-delta type
regions. At this time, we are initiating a Major Flare Watch. The primary
target region should switch to NOAA 14419 due to the high chance for
further >M5.0 activity as it transits the solar limb, however close
attention should be paid to NOAA 14420 (N16E21) as this region also shows
potential for isolated >M5.0 events in the next 24-48 hours.
The position of NOAA 14419 on 24-April-2026 at 11:30 UT is:
N15W67, (849", 276")

Dear Collaborators,
Solar activity is increasing. Since the last message, NOAA 14420 was the
site of multiple flares, including an M1.2 at 04:50 UT today. However, the
largest flare of the last 24 hours was produced by NOAA 14419, which was an
M4.3 at 08:40 UT today, though this region is now situated at the
northwestern limb. NOAA 14420 continues to be productive as it further
transits the disk, and retains its beta-gamma configuration. Additionally,
a large bright region beyond the northeastern limb appears to be
approaching with signs of significant flux. Sunspot activity from NOAA
14420 appears to have settled slightly though there are still signs of
dynamic motion in the region. NOAA 14420 will continue as the target
region, further C-class activity is anticipated with the chance for
additional isolated M-class events.
The position of NOAA 14420 on 23-April-2026 at 11:30 UT is:
N16E31, (-473", 330")
