Dear Collaborators,
Solar activity has further reduced. A number of flares were produced in the
last 24 hours, the largest being a C8.0 at 15:15 UT yesterday from NOAA
14238. The target region has reduced in complexity, and is now classified
as a beta-gamma type region. NOAA 14236 will remain the target region given
its apparent size and emerging flux. Further C-class activity is expected
in the next 24 hours.
The position of NOAA 14236 on 04-October-2025 at 11:30 UT is
N10W38, (583", 80")

Dear Collaborators,
Solar activity has slightly reduced. Several flares were produced in the
last 24 hours, the largest being an M1.5 from NOAA 14236 at 05:00 UT today.
NOAA 14236 has reduced in complexity and is now classified as a beta-gamma
type region. Meanwhile, NOAA 14232, in close proximity to NOAA 14236, is
now classified as a beta-gamma-delta region. The area surrounding these
regions contains substantial emerging flux. As such, NOAA 14236 will remain
the target region. Further C-class activity is expected with additional
isolated low M-class events.
The position of NOAA 14236 on 03-October-2025 at 11:30 UT is
N10W21, (339", 64")

Dear Collaborators,
Solar activity remains at an intermediate level. A small number of flares
were produced in the last 24 hours, with two M1.2 flares being produced at
16:36 UT yesterday and 02:00 UT today from NOAA 14232 and NOAA 14226,
respectively. Both NOAA 14230 and NOAA 14236 remain classified as
beta-gamma-delta regions and have both achieved equal sunspot areas. Given
the proximity of NOAA 14230 to the limb, the target region will now switch
to NOAA 14236. Additionally, given the lack of substantial activity from
either region, we are ending the MFW at this time. However, close attention
should still be paid to the development of the target region. Further
C-class and low M-class activity is expected.
The position of NOAA 14236 on 02-October-2025 at 11:30 UT is

Dear Collaborators,
Solar activity remains at an intermediate level. Several flares were
produced in the last 24 hours, the largest being an M1.2 from NOAA 14232 at
02:15 UT today. There are now two active regions on the disk that are
classified as beta-gamma-delta regions. These are NOAA 14230 and NOAA 14236
respectively. As NOAA 14230 is surrounded by several other active regions
and is in an area of substantial emerging flux, this will become the
primary target region. However, attention should also be paid to the larger
of the two regions, NOAA 14236. Given this occurrence, the MFW will be
sustained for a further 24 hours due to the increased probability of a
large flare. Additional M-class activity is likely, with a chance for an
isolated >M5 event in the next 24-48 hours.
The position of NOAA 14230 on 01-October-2025 at 11:30 UT is
S11W44, (655", -261")

Dear Collaborators,
Solar activity persists at an elevated level. The largest flare produced
since the last message was an M2.7 from NOAA 14227 at 09:33 UT today. NOAA
14232 produced an additional M1.2 event in the last 24 hours and continues
to show signs of elevated flux. NOAA 14232 will remain the target region
and the MFW will remain active for what may be the last 24 hours. Further
isolated M-class events are possible with a very small chance for a >M5
event.
The position of NOAA 14232 on 30-September-2025 at 11:30 UT is
N05E28, (-449", -16")

Dear Collaborators,
Solar activity levels remain elevated. Several flares have been produced
since the last message, the largest being an M3.6 at 01:37 UT today. NOAA
14232 has further increased in complexity over the last 24 hours and is now
classified as a beta-gamma type region. While no major flares were produced
since the last message, the MFW will remain active for a further 24 hours
due to the continued development of the target region. Further M-class
activity is expected in the coming 24 hours, with a slight chance for an
additional >M5 event.
The position of NOAA 14232 on 29-September-2025 at 11:30 UT is

Dear Collaborators,
Solar activity has reached a high level since the last message. The largest
event was an M6.5 flare at 08:34 UT today, produced by NOAA 14232. This
region has increased in its magnetic complexity to be a beta/C-type. 14232
shall become the target region, and we are issuing a Major Flare Watch
alert at this time due to the increased possibility of another >M5 flare
within the coming days.
The position of the NOAA 14232 on 28-Sep-2025 at 11:30 UT is:
N03E57 (-803", -12")

Dear Collaborators,
Solar activity has returned to a low-M level since the last message.
The largest event was an M1.6 flare at 19:49 UT yesterday from an
unnumbered region near the northeast limb. This region also produced
an M1.1 and nine low-C flares. To the south of this limb region, NOAA
14232 (alpha/H-type, N02E71) and NOAA 14226 (beta/C-type, S10W14)
also produced an M1.1 flare at 07:03 UT today and an M1.0 flare at
03:29 UT today, respectively. Today, the target should switch to the limb
region, because of its high productivity. Yesterday’s target, NOAA 14217,
has almost rotated out of Earth-view. Further C-class activity is expected
with more low-M flare possible within the next 24 hours.
The approximate position of the target on 27-Sep-2025 at 11:30 UT is:
N19E71 (-850", 170")

Dear Collaborators,
The level of solar activity is low. The largest event in the past
24 hours was a C3.4 flare at 13:54 UT yesterday from the
target region NOAA 14217. This region also produced four
~C2 flares and was classified as a beta/C-type. Today, the
target will remain with 14217 for a further 24 hours. In addition,
an unnumbered region beyond the northwest limb also produced
five ~C2 flares, including its largest being a C2.4 at 06:14 UT
today. More low-C activity is expected from these two regions
in the next 24 hours.
The position of NOAA 14217 on 26-Sep-2025 at 11:30 UT is:
S17W82 (906", -293")

Dear Collaborators,
Solar activity has been at a moderate-to-low level since the
last message. NOAA 14224 (beta/C-type, S13W57) produced
the largest event – an M1.6 at 18:57 UT yesterday and a C2.2
flare. The target region, NOAA 14217, was the source of four
low-C flares. It has developed into a beta-gamma/D-type
sunspot group. Today, the target shall continue as 14217 (with
NOAA 14224 in the field of view). Note that NOAA 14226
(beta-gamma/D-type, S11E11) also produced two ~C5 flares
in the period. Further C-class activity is expected with another
low-M flare likely in the following 24 hours.
The position of NOAA 14217 on 25-Sep-2025 at 11:30 UT is:
S17W68 (849", -319")
