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")

Dear Collaborators,
Solar activity has remained at a low level since the last message.
A few low C-class flares occurred in the period, the largest being
a C1.4 flare at 13:20 UT today from an unnumbered region near
the southeast limb (S12E78), which produced two additional ~C1
flares during the period. Today, target will switch to this limb region.
Yesterday's target NOAA 14122 retains a beta/D-type configuration
but exhibited decay in sunspot size; it produced a C1.2 flare during
the period. Further low-level C-class flares are expected over the
next 24 hours.
The approximate position of the target region on 30-June-2025
at 11:30 UT is:
S12E78, (-903", -205")

Dear Collaborators,
Solar activity has increased slightly since the last message.
The largest event was a C4.0 at 19:40 UT yesterday from a
newly-emerged active region NOAA 14126 (beta/C-type,
N07W34) which is composed of small pores. A C1.2 flare at
13:21 UT yesterday was produced by the target region NOAA
14122. This region has been stable in the magnetic complexity
of a beta/D-type, with a sustained increase in the sunspot size
to 140 ÎĽh. Today, the target region should remain with 14122,
considering its high spot maturity and large spot area on the
disk. Additional low-C flares are expected in the following 24
hours.
The position of NOAA 14122 on 29-June-2025 at 11:30 UT is
N13E08 (-128", 169")

Dear Collaborators,
Solar activity has been consistent since the last message.
NOAA 14120 (beta/D-type, N07W57) produced the largest
magnitude flare - a C1.2 one at 13:21 UT yesterday, while
this region displayed visible magnetic signs of decay. The
target region, NOAA 14122, has been flare-quiet with a
beta/D-type sunspot group, but it has grown in the spot area
during the period. Today, NOAA 14122 shall continue as the
target. High-B activity is expected, with low-C flares likely in
the next 24-hour period.
The position of NOAA 14122 on 28-June-2025 at 11:30 UT is
N13E21 (-330", 174")

Dear Collaborators,
Solar activity has remained at a low level over the past 24 hours.
The largest event was a C1.9 flare at 02:49 UT today, produced
by NOAA 14122. This region also produced three ~C1 flares and
was the most productive region. It has been classified as a
beta/D-type magnetic configuration, with its spot area growing.
Yesterday’s target, NOAA 14117, has been flare-quiet in the period.
Today, the target region shall switch to NOAA 14122 from NOAA
14117. Additional low-C flares are expected in the coming 24 hours.
The position of NOAA 14122 on 27-June-2025 at 11:30 UT is
N13E34 (-515", 179")
