Dear Collaborators,
Solar activity has been at a low level since the last message.
The largest event during the period was a C8.9 flare at 21:44 UT
yesterday produced by yesterday's target NOAA 14140 (S15E37).
14140 has decayed to a beta/C-type region and been flare quiet
since the beginning of UT today. There was a newly emerged region,
now numbered as NOAA 14141, producing nine low C-class flares
(the largest one being a C3.2) today. We will switch the target to
NOAA 14141, which was designated as a beta/C-type configuration.
Although this region is rotating over the west limb, its loops can still
be seen above the limb. Further C-class flares are expected from
various regions in the next 24 hours.
The position of NOAA 14141 on July 14 at 15:30 UT is:
S13W85 (916", -217")

Dear Collaborators,
Solar activity is at a moderate-to-low level. The target region NOAA
14140 (S15E52, beta/D-type) remained the most flare-productive
region on the visible disk, producing over ten C-class flares, including
the largest event in the period—a C8.9 flare at 03:46 UT today. NOAA
14140 shall remain the target region. Notably, NOAA 14136 (N19E18,
beta-delta/D-type) also produced a C7.0 flare during the period. Further
C-class activity is expected, with a chance of low M-class flares in the
coming days.
The position of NOAA 14140 on 13-July-2025 at 15:30 UT is:
S15E52 (-720",-285")

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The largest event in the period was an M2.3 flare at 08:29 UT today,
produced by the target region, now designated as NOAA 14140 (S15E61,
beta/C-type). This region also produced two additional low M-class flares
(M1.4 and M1.6) and several C-class flares during the period. The target
will remain on this region today. Further C-class activity is expected,
with
a chance of additional low M-class flares in the next 24–48 hours.
The position of NOAA 14140 on 12-July-2025 at 19:30 UT is:
S15E61 (-798",-275")

Dear Collaborators,
Solar activity has increased slightly since the last message. Yesterday's
target, NOAA 14136 (N19E42), retains a beta-gamma configuration but
has been flare-quiet during the period. The largest event was a C8.9
flare at 19:27 UT yesterday from the southeast limb region (S15E82)
mentioned in yesterday's message. This region also produced a C8.0
flare and over ten additional C-class flares in the period. Today, the
target
shall switch to this limb region. Further C-class activity is expected,
with
a chance of low M-class flares in the next 24–48 hours.
The approximate position of the target region on 11-July-2025
at 19:30 UT is:
S15E82 (-902",-252")

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")
