Dear Collaborators,
Solar activity continues at a low-to-moderate level. The target region
has been numbered as NOAA 14028 (S17E58, beta/D-type), which
produced seven C-class flares in the period. Today the target shall
remain with this region, due to its activity history and complex magnetic
connectivity with the activity region to its east. The largest event in
the period was a C7.9 flare at 19:12 UT yesterday, produced by NOAA
14019 (N06W16). This region retains a beta-delta configuration and
produced another three low C-class flares. C-class flares are expected,
with a chance of an isolated low M-class flare in the next 24-48 hours.
The position of NOAA 14028 on 14-Mar-2025 at 12:30 UT is:
S17E58 (-784",-219")

Dear Collaborators,
Solar activity continues at a low-to-moderate level. The limb target
(S18E75) remained the most flare-productive region in the period,
being the source of over ten C-class flares, including three middle
C-class flares (C6.0, C5.8, and C4.1). Today the target shall remain
with this limb region, although the largest event in the period was
produced by NOAA 14012 (S14W91) - a C6.8 flare occurred at
07:40 UT today. Additionally, NOAA 14019 (N06W03) retains a
beta-delta configuration and also produced several low C-class
flares in the period. C-class flares are expected, with a chance
of an isolated low M-class flare in the next 24-48 hours.
The approximate position of the target region on 13-Mar-2025 12:30 UT is:
S18E75 (-887'', -266'')

Dear Collaborators,
Solar activity has been at a low-to-moderate level since the last message.
Yesterday's target region, NOAA 14019 (N07E11), produced only two low
C-class flares in the period and has been designated as a beta-delta
configuration. The largest event in the period was a C9.6 flare at 21:11 UT
yesterday from NOAA 14024 (N05W61), which has now nearly lost all
sunspots. The most flare-productive region in the period was located at
the southeast limb (S17E88). This limb region was the source of over ten
C-class flares, including three mid-to-high C-class flares (C7.2, C8.8, and
C5.7). Today, the target will switch to this limb region. C-class flares
are
expected, with a possibility of an isolated low M-class flare in the next
24-48 hours.
The approximate position of the target region on 12-Mar-2025 12:30 UT is:
S17E88 (-922'', -276'')

Dear Collaborators,
Solar activity has slightly increased since the last message. A newly
emerged region (N05W46) produced the largest event in the period
- an M1.1 flare at 13:03 UT today. Yesterday's target, now numbered
as NOAA 14021 (S06E64, beta/C-type), produced a C2.7 flare today.
Additionally, NOAA 14019 (N07E24) was the source of three ~C2.0
flares during the period. This region has developed into a beta-gamma
-delta configuration with a significant increase in sunspot area and
number of spots. Today the target will switch to this region due to its
rapid evolution and complex magnetic configuration. Low-to-moderate
C-class flares are expected, with a chance of an isolated low M-class
flare in the next 24-48 hours.
The position of NOAA 14019 on 10-Mar-2025 at 12:30 UT is:
N07E24 (-391",227")

Dear Collaborators,
Solar activity remains low. The largest event since the last message
was a C2.6 flare at 18:32 UT yesterday, produced by the limb region
(S06E89) mentioned in yesterday's message. This region was also
the source of another C2.5 and two ~C1 flares during the period.
Today the target shall switch to this region. Yesterday's target NOAA
14012 (S14W45) retains a beta-gamma configuration and produced
three ~C1 flares in the period. 14012 shows further decay, with a
decreasing number of spots. Low C-class flares are expected in the
next 24-hour period.
The approximate position of the target region on 10-Mar-2025 12:30 UT is:
S06E89 (-960'', -98'')

Dear Collaborators,
Solar activity has been at a low level. The largest event since
the last message was a C4.0 flare at 17:38 UT on March 8 due
to a filament eruption from a limb region (S06E89). The target
region NOAA 14012 was the source of seven C1-C2 flares during
the period. 14012 retains a beta-gamma/E-type configuration
but experiences a further decay. Additional C-class activities are
expected in the following 24-hour period.
The position of NOAA 14012 on March 9 at 04:30 UT is:
S14W25 (397", -125")

Dear Collaborators,
There was an isolated M1.6 flare at 20:54 UT on March 7
from NOAA 14016 (S26E04). 14016 retains a beta-gamma/
C-type configuration and seems to interact with the target
region NOAA 14012 via overlying loops. 14012 was the source
of six low C-class (C1-C2) flares during the period. It retains
a complex beta-gamma/E-type configuration but has entered
its decay phase. Today we will continue to watch this region.
Further C-class flares are expected in the next 24 hours.
The position of NOAA 14012 on March 8 at 08:30 UT is:
S13W15 (244", -101")

Dear Collaborators,
Solar activity has been at a very low level with the GOES 1-8 flux
mostly flat at ~C1. The largest event over the past 24 hours was a
C1.7 flare at 00:09 UT today from a northeast limb region (N06E88).
The target NOAA 14012 produced a C1.6 flare at 20:02 UT yesterday.
It retains a beta-gamma/E-type configuration. Only C-class activities
are expected in the next 24 hours.
The position of NOAA 14012 on March 7 at 08:30 UT is:
S13W00 (0", -97")

Dear Collaborators,
Solar activity increased in the past 24 hours. An isolated M1.8 flare
(at 11:45 UT on March 5) was produced by NOAA 14016 (S26E30)
that was mentioned in yesterday's message. 14016 has been designated
as a beta-gamma/C-type configuration but with a small sunspot area.
The target region NOAA 14012 only produced two low C-class flares
during the period. It retains a complex beta-gamma/E-type configuration
but increases the sunspot area and number of spots. Today we will
continue to watch NOAA 14012. Further C-class activities are expected
in the following 24 hours.
The position of NOAA 14012 on March 6 at 08:30 UT is:
S12E14 (-229", -83")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C4.6 flare at 15:34 UT yesterday
produced by NOAA 14012. 14012 also produced four ~C2.0
flares during the period. It has been designated as a beta-gamma/
E-type configuration with increasing the sunspot area and number
of spots. Today the target will switch to this region. Please note
that a newly emerged region, NOAA 14016 (S25E43, beta/B-type),
also produced four ~C1.5 flares. Yesterday's target NOAA 14007
has lost its delta spot and continues to be flare quiet. C-class flares
are expected from various regions in the next 24-hour period.
The position of NOAA 14012 on March 5 at 08:30 UT is:
S13E28 (-444", -111")
