Dear Collaborators,
Solar activity has decreased further since the last message. The target
region has been designated NOAA 14136 (N19E55) with a beta-gamma
magnetic configuration. It produced only a C1.7 flare during the period.
Today, the target will remain on this region due to its activity history
and
magnetic complexity. Notably, an unnumbered southeast limb region
(S14E88) produced nine C-class flares, including the two largest of the
period, both reaching magnitude C4.3. Further C-class activity is expected,
with a chance of low M-class flares in the next 24–48 hours.
The position of NOAA 14136 on 10-July-2025 at 15:30 UT is:
N19E55 (-732",272")

Dear Collaborators,
Solar activity has decreased slightly since the last message.
The largest event since the last message was an M1.3 flare
at 04:10 UT today, produced by the limb target region (N20E78,
still unnumbered). The target will remain on this region. Further
M-class activity is possible over the following 24-48 hours.
The approximate position of the target region on 9-July-2025
at 11:30 UT is:
N20E78 (-868",310")

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
Yesterday's target region, NOAA 14127 (S20W79), produced a C1.8
flare during the period. The largest event in the period was an M2.5 flare
at 03:42 UT today from an unnumbered region near the northeast limb
(N19E88), which also produced over ten low C-class flares. Today we
will watch this limb region. Further C-class activity is expected, with a
chance of another M-class flare in the next 24–48 hours.
The approximate position of the target region on 8-July-2025
at 11:30 UT is:
N19E88 (-891",304")

Dear Collaborators,
Solar activity has increased further since the last message, although
yesterday’s target region NOAA 14130 remained flare-quiet during
the period. The largest event in the period was a C1.6 flare at 11:13
UT today from NOAA 14127 (S19W66, beta/D-type), which also
produced nine additional ~C1 flares. Today, the target will switch to
NOAA 14127 due to its ongoing flux emergence. Further low C-class
flares are expected over the next 24 hours.
The position of NOAA 14127 on 7-July-2025 at 11:30 UT is:
S19W66 (816",-329")

Dear Collaborators,
Solar activity has increased slightly since the last message.
The largest event in the period was a C1.4 flare at 10:41 UT
today, produced by the target region NOAA 14130 (S11W01,
beta/C-type). This region also produced a C1.3 flare during
the period. Today, the target will remain on this region. Additionally,
NOAA 14127 (S19W51, beta/C-type) produced a C1.3 flare in
the period. Further low C-class flares are likely over the next
24 hours.
The position of NOAA 14130 on 6-July-2025 at 07:30 UT is:
S11W01 (16",-236")

Dear Collaborators,
Solar activity remains low. The largest event since the last message
was a C1.5 flare at 12:10 UT today, produced by the target region
NOAA 14130 (S10E13, beta/B-type). The target will remain on this
region, with high-B activity expected and low-C flares likely over the
next 24 hours.
The position of NOAA 14130 on 5-July-2025 at 11:30 UT is:
S10E13 (-209",-217")

Dear Collaborators,
Solar activity remains at a low level. Yesterday's target region has
fully rotated beyond the west limb. The largest event in the period
was a C2.5 flare at 07:38 UT today from NOAA 14130 (S12E16),
which also produced a C1.3 flare during the period. The target region
will switch to NOAA 14130 today due to ongoing flux emergence.
Additionally, NOAA 14129 (N02W13) produced two C1 flares during
the period. Further low C-class flares are expected over the next 24
hours.
The position of NOAA 14130 on 4-July-2025 at 15:30 UT is:
S12E16 (-255",-247")

Dear Collaborators,
Solar activity has increased slightly since the last message.
The largest event in the period was a C2.6 flare at 18:32 UT
yesterday, produced by the limb target region NOAA 14126
(N07W91). This region also produced four additional ~C2.0
flares during the period. 14126 will remain the target today
until it fully rotates beyond the west limb. Further C-class
activity is expected over the next 24 hours.
The position of NOAA 14126 on 3-July-2025 at 11:30 UT is:
N07W91 (936",115")

Dear Collaborators,
Solar activity has remained at a low level since the last message.
Yesterday's target, NOAA 14130 (S12E47), has decayed into a
region composed of small pores, producing only a ~C1 flare. The
largest event during this period was a C1.6 flare at 14:49 UT today
from a northwest limb region NOAA 14126 (N07W76, beta/D-type),
which is undergoing notable flux emergence and produced three
additional ~C1 flares in the period. Today, the target will switch to
NOAA 14126 until it rotates over the west limb. C-class flares are
expected in the next 24 hours.
The position of NOAA 14126 on 2-July-2025 at 11:30 UT is:
N07W76 (909",102")

Dear Collaborators,
Solar activity continues at a low level. The largest event since the last
message was a C1.9 flare at 18:25 UT yesterday, produced by the limb
target region now numbered NOAA 14130 (S12E61, alpha/A-type). This
region also produced a C1 flare and a B9 flare during the period. Today,
the target will remain focused on this region, although it shows signs of
decay. Further low C-class flares are expected over the next 24 hours.
The position of NOAA 14130 on 1-July-2025 at 11:30 UT is:
S12E61 (-808",-219")
