Dear Collaborators,
Solar activity returned to a low level since the last message. The largest
event in the last 24 hours was a C3.0 flare from NOAA 14030.
Yesterday's target, NOAA 14025 only produced a C1.9 flare at 23:59 UT
on 3/18. This region significantly reduced the area of trailing
(negative) sunspots and re-classified as a beta type.
NOAA 14031, located at the Northeast of NOAA 13025, undergoes flux
emergence from the central area, retaining magnetic complexity of
a beta-gamma type and producing 3 low-C class flares. Today we will
switch our target to NOAA 14031, at the central area of mixed
polarity expecting additional C class events.
The position of the target in NOAA 14031 on 19-March-2025 at
16:00 UT is: N15W30 (476", 354").

Dear Collaborators,
Solar activity has been at a low-to-moderate level since the last
message. The largest events in the last 24 hours were two consecutive
near-M class flares (C9.8 at 19:04 UT and another M1.0 at 19:25 UT
on 3/17) both from NOAA 14033 in the Northeastern quadrant. After
these events, however, the tiny sunspots of this region vanished.
The target region, NOAA 14028 produced two low-C class flares. This
region retains a beta-gamma type magnetic configuration, but its
sunspots started to fade in the recent 12 hours.
NOAA 14025 in the Northwest quadrant also produced two low-C class
flares in the last 12 hours and is increasing both its sunspot area
and number of sunspots. Today our default target will switch to NOAA
14025, at the central area of mixed polarity. Additional C class events
are expected.
The position of the target in NOAA 14025 on 18-March-2025 at
16:00 UT is: N09W33 (524", 256").

MM#009 Default Target
Dear Collaborators,
Solar activity remains to be low since the last message. The largest
event in the last 24 hours was a C7.8 flare at 5:21 UT today(3/17)
from the target region, NOAA 14028. The second largest event, a C6.5
flare at 22:27 UT yesterday was also from NOAA 14028 from its trailing
(positive) sunspot area. In other area of the solar disk, there are new
flux emergence at NOAA 14025 and 14031, both in the Northwest
quadrant, but not showing significant flare activity yet.
We will continue to observe the trailing area of NOAA 14028 as a
default target for the next 24 hours. Additional C class events are
expected.
The position of the target in NOAA 14028 on 17-March-2025 at
15:30 UT is: S19E25 (-385", -224").

Dear Collaborators,
Solar activity has declined to a low level since the last message.
The target region NOAA 14028 (S17E36) and its nearby region
14030 (S16E54) both have a beta-gamma configuration and
produced seven low C-class flares in the period. NOAA 14028
is undergoing significant magnetic flux emergence in its intermediate
portion and shall remain the target today. Please note that the
largest event in the period was a C4.2 flare at 07:39 UT today,
produced by NOAA 14019 (N06W42). This region has developed
into a beta-gamma-delta configuration and produced another C4.1
flare yesterday. 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 16-Mar-2025 at 08:30 UT is:
S17E36 (-543",-187")

Dear Collaborators,
Solar activity has been at a moderate level since the last message.
The largest event in the period was an M1.1 flare at 22:18 UT
yesterday, produced by the target region NOAA 14028 (S18E52).
This region has developed into a beta-gamma configuration and
shall remain the target. C-class flares are expected, with the
additional chance of an isolated low M-class flare in the next
24-48 hours.
The position of NOAA 14028 on 15-Mar-2025 at 08:30 UT is:

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'')
