Dear Collaborators,
Solar activity has been at a low-to-moderate level since the last
message. The target region NOAA 14079 produced an M1.9 flare at
23:55 UT yesterday (5/11) followed by several low-C class events
today but has completed the West limb passage.
A region rotated from the Northeast limb has been showing vigorous
ejective activities over the limb in EUV 304A images in the recent
24 hours. This region is the source of 3 C class flares so far, with
the largest being a C5.2 at 23:34 UT yesterday. Today we will switch
the target to this region expecting additional C class activities.
The position of the target on 12-May-2025 at 15:00 UT is:
N14E81 (-910", 243").

Dear Collaborators,
Solar activity has increased slightly since the last message.
The largest event in the period was a C5.5 flare at 16:16 UT
yesterday from the target region NOAA 14079 (N08W85).
14079 remained the most flare-productive region on the disk,
producing seven additional low C-class flares when it was
rotating over the west limb. Today NOAA 14079 shall remain
the target region. Further C-class activity is expected over
the next 24 hours.
The position of NOAA 14079 on 11-May-2025 at 07:30 UT is:
N08W85 (937",136")

Dear Collaborators,
Solar activity has declined to a low level since the last message.
The target region NOAA 14079 (beta-gamma/D-type) remained
the most flare-productive region on the disk, producing nine low
C-class flares and the largest magnitude event in the period—a
C3.1 flare at 00:55 UT today. NOAA 14079 shall remain the target
region. Further C-class activity is expected, with a slight chance
of an isolated low M-class flare over the next 24 hours.
The position of NOAA 14079 on 10-May-2025 at 11:30 UT is:
N08W74 (905",146")

Dear Collaborators,
Solar activity continues at a low-to-moderate level. The target
region NOAA 14079 (N09W59, beta-gamma/E-type) remained
the most flare-productive region in the period, being the source
of nine C-class flares, including two middle C-class flares (C6.4
and C4.9). Today the target shall remain with this region, although
NOAA 14082 (S10W00) produced the largest event in the period
—a C7.1 flare at 14:54 UT yesterday. Further C-class activity is
expected, with a slight chance of an isolated M-class event in
the next 24-48 hours.
The position of NOAA 14079 on 9-May-2025 at 11:30 UT is:
N09W59 (806",176")

Dear Collaborators,
Solar activity has been at a low-to-moderate level since the last message.
The largest event during the period was a C7.0 flare at 11:28 UT today,
attributed to NOAA 14082 (S11E14, beta-gamma/D-type). However, a flare
from the target region NOAA 14079 (N08W45) also contributed to the soft
X-ray flux. 14079 retains its size (1220 µh) and complexity (beta-gamma),
producing eight additional low C-class flares in the period. Today the
target
region shall remain with NOAA 14079 with a focus towards its northern
mixed polarities. Further C-class activity is expected over the next 24
hours,
with a slight chance for an isolated M-class event.
The position of NOAA 14079 on 8-May-2025 at 11:30 UT is:

Dear Collaborators,
Solar activity has increased slightly since the last message. The largest
event was a C4.5 flare at 17:02 UT yesterday from the target region
NOAA 14079 (N08W33). 14079 retains its size and was the most
flare-productive region on the disk, producing over 20 low C-class
flares during the period, although its magnetic complexity has declined
to a beta–gamma type. NOAA 14079 shall remain the target region
today, and further C-class activity is expected over the next 24 hours.
The position of NOAA 14079 on 7-May-2025 at 11:30 UT is:

Dear Collaborators,
Solar activity remains low, with GOES soft X-ray flux around C2.
More than ten low C-class flares have been produced since the
last message, the largest being a C2.3 flare from NOAA 14082
(S11E42), which has developed into a beta–gamma configuration.
The target region NOAA 14079 (N08W19) increased in size to
1230 μh and in complexity to a beta–gamma–delta classification,
producing three low C-class flares in the period. NOAA 14079
shall remain the target region, and further C-class activity is
expected over the next 24 hours.
The position of NOAA 14079 on 6-May-2025 at 11:30 UT is:

Dear Collaborators,
Solar activity remains at a low level. Several low C-class flares were
produced since the last message, the largest being two C1.8 flares
from NOAA 14082 (S11E61, beta/D-type) and the target region NOAA
14079 (N08W03, beta-gamma/E-type). NOAA 14079 retains its size
and complexity and is undergoing some new flux emergence in the
northern portion of the main positive sunspot. NOAA 14079 shall
continue as the target region, with further C-class activity expected
over the next 24 hours.
The position of NOAA 14079 on 5-May-2025 at 07:30 UT is:

Dear Collaborators,
Solar activity continues at low levels. NOAA 14079 remains unchanged in
terms of size and complexity since the last message, and has remained
quiescent. A small EFR in the southeast quadrant was the source of a C5.4
flare at 12:26 UT today. NOAA 14079 shall continue as the target region for
a further 24 hours although no significant increase in activity is expected.
The position of NOAA 14079 on 4-May-2025 at 11:30 UT is:
N08E08, ( -131", 195" )

Dear Collaborators,
Solar X-ray flux remains steady around the low C-level. The target region
NOAA 14079 has remained relatively quiescent since the last message, the
largest event being a C3.7 flare at 21:39 UT yesterday. The region has now
been downgraded to a beta-gamma region and remains unchanged in terms of
size. Only isolated low-level events expected over the next 24 hours.
The position of NOAA 14079 on 3-May-2025 at 11:30 UT is:
N07E20, ( -324", 177" )
