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")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C3.4 flare at 00:47 UT produced
by NOAA 14006 (N19W54) which has a beta/C-type configuration.
14006 was also the source of two C2 flares during the period.
Please note that NOAA 14012 (S13E42) was the source of six
low C-class flares including a C3.1. 14012 has been designated
as a beta-gamma/D-type region. The target region NOAA 14007
was flare quiet over the past 24 hours but it has been designated
as a beta-gamma-delta/D-type region, continuing to increase the
sunspot area. Today we continue to watch NOAA 14007 for a
further 24 hours. C-class flares are expected from various regions
in the following 24 hours.
The position of NOAA 14007 on March 4 at 08:30 UT is:
S10W49 (720", -88")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C2.4 flare at 20:57 UT produced
by NOAA 14007. 14007 was also the source of another three
low C-class flares. This region retains a beta/D-type configuration
but increased the sunspot area prominently. Today the target
will switch to NOAA 14007. Please note that previous target
NOAA 14006 also produced three ~C1 flares in the period.
Yesterday's target has been numbered as NOAA 14011, having
a beta/C-type configuration. It was flare quiet in the past 24 hours.
Further C-class flares are expected in the next 24 hours.
The position of NOAA 14007 on March 3 at 08:30 UT is:
S10W36 (562", -69")

Dear Collaborators,
Solar activity has been at a low level since the last message. The
largest event was a C9.6 flare at 22:44 UT on 3/1 from the Southeast
limb, but the source region is still unclear, as the sunspot is not
visible at the latitude of this event. Yesterday's target, NOAA 14006
further reduced the sunspot area with no record of flare activity.
Two new sunspots are emerging close to the Southeast limb at the
latitude range 10 to 20 degree South, both of which are yet unnumbered.
The Western spot located at the latitude 18 degree South repeats
several low-C class flares in the past 24 hours. Today, we will switch our
default target to this small region following this flare history.
Additional
C-class events are expected.
The position of the target on 2-March-2025 at 17:00 UT is:
S18E49 (-698", -229").
