Dear Collaborators,
Solar activity has grown to a high level. The largest event since
the last message was an X1.9 flare at 23:37 UT yesterday from
the target region NOAA 14114. This region also produced an
M4.6 flare at 00:02 UT today. It retained a beta-gamma/E-type
magnetic configuration, showing signs of decay in its leading
portion. Today, the Major Flare Watch shall continue as NOAA
14114. More C-class activity is expected, with a chance for
another >M5 flare in the next 24-48 hours.
The position of NOAA 14114 on 20-June-2025 at 11:30 UT is
N21W48 (656", 321")

Dear Collaborators,
Solar activity has decreased to an intermediate level since the
last message. The target region NOAA 14114 produced 12
C-class flares, with the largest being a C8.0 at 09:06 UT. This
region lost its delta configuration to become a beta-gamma/E-type,
but exhibited signs of shearing and additional flux emergence.
Today the Major Flare Watch shall remain with NOAA 14114.
Further C-class activity is expected, with a chance for an isolated
>M5 flare in the following 24 hours.
The position of NOAA 14114 on 19-June-2025 at 11:30 UT is
N18W33 (490", 272")

Dear Collaborators,
Solar activity has returned to a high level. The largest event
in the past 24 hours was an X1.2 flare at 21:38 UT yesterday
produced by the target region NOAA 14114. This region has
remained stable in sunspot area and classification as a
beta-gamma-delta/E-type, showing signs of separation of its
main spots. Today, the Major Flare Watch shall continue as
NOAA 14114. More low-M activity is probable, with another
>M5 flare likely in the following 24 hours.
The position of NOAA 14114 on 18-June-2025 at 11:30 UT is
N18W19 (293", 271")

Dear Collaborators,
Solar activity has dropped to an intermediate level over
the past 24 hours. Two ~M1 flares, a M1.1 at 14:43 UT
yesterday and a C9.9 at 06:14 UT today, were attributed
to NOAA 14109 (S17W91, beta/C-type) and an unnumbered
region (S15E89), respectively. The target region NOAA
14114 was only the source of four mid-C flares. It retained
a beta-gamma-delta/E-type magnetic configuration, and
continued to develop additional spots in its intermediate and
tail portions. Today the Major Flare Watch shall be extended
for a further 24 hours with NOAA 14114. More low-M activity
is very likely, with a chance for an isolated >M5 flare in the
following 24 hours.
The position of NOAA 14114 on 17-June-2025 at 11:30 UT is
N18W08 (125", 272")

Dear Collaborators,
Solar activity has continued at a high level. The largest events
since the last message were an M8.5 flare at 17:45 UT yesterday
and an M6.3 flare at 09:17 UT today from NOAA 14114. This region
has been classified as a beta-gamma-delta/E-type sunspot group,
with an emergence of new visible magnetic fluxes surrounding its
main spots. Yesterday’s target NOAA 14105 showed no M-class
activity as it is currently rotating out of Earth-view. Today the Major
Flare Watch shall switch to 14114 from 14105, due to a higher
probability of another >M5 flare from 14114 in the coming days.
The position of NOAA 14114 on 16-June-2025 at 11:30 UT is
N17E05 (-79", 258")

Dear Collaborators,
Solar activity has increased in the last 24 hours. NOAA 14105 was the
source of an M6.8 flare at 22:51 UT yesterday. NOAA 14105 has shown an
increase in activity since the last message as it continues its transit of
the southwest limb. At this time we are issuing a Major Flare Watch with
NOAA 14105 as the target region while it remains in view. Further M-class
activity is anticipated, with the potential for an additional isolated >M5
event in the next 24-48 hours.
The position of NOAA 14105 on 15-June-2025 at 11:30 UT is
S15W78, (892", -248")

Dear Collaborators,
Solar activity remains at a low level. A number of flares were produced in
the last 24 hours, the largest being an M1.2 from NOAA 14105 at 20:49 UT
yesterday. NOAA 14105 is now at the southwest limb and still shows a
substantial degree of emerging flux. This region will remain the target
region while it begins its transit over the southwest limb. Further C-class
activity is expected with a slight chance for an additional isolated
M-class flare in the next 24 hours.
The position of NOAA 14105 on 14-June-2025 at 11:30 UT is
S15W66, (834", -250")

Dear Collaborators,
Solar activity has remained consistent. A number of C-class flares were
produced, the largest being a C5.8 from newly numbered active region NOAA
14115 at 17:39 UT yesterday. While NOAA 14105 has continued to display
dynamic sunspot activity and bright emerging flux, activity from this
region has been minor. As NOAA 14105 continues its motion towards the
southwest limb, it will remain the target region. Further C-class activity
is likely in the next 24 hours.
The position of NOAA 14105 on 13-June-2025 at 11:30 UT is
S15W53, (730", -253")

Dear Collaborators,
Solar activity has slightly increased since the last message. Several
flares were produced, the largest being a C8.5 from newly numbered active
region NOAA 14114 at 19:07 UT yesterday. NOAA 14105 has shown an increase
in emerging flux and notable sunspot activity in the last 24 hours, as it
approaches the southwestern limb. Additionally, NOAA 14107 is now
classified as a beta-delta region and both regions have increased in
apparent sunspot area. While the flare production from NOAA 14105 has been
relatively average, the increased activity in this region will continue to
be monitored and it will remain the target region. Further C-class activity
is expected with a very small chance of a low M-class event.

Dear Collaborators,
Solar activity remains at a low level. Several low C-class flares were
produced, the largest being a partially occulted C3.0 from a currently
unnumbered active region at the northeast limb. NOAA 14105 and NOAA 14107
have shown notable signs of sunspot dynamism, but have remained relatively
quiet. Both show moderate levels of emerging flux. NOAA 14105 will continue
as the target region, but attention should also be paid to NOAA 14107.
Further C-class activity is anticipated.
The position of NOAA 14105 on 11-June-2025 at 11:30 UT is
S15W24, (327", -254")
