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").

Dear Collaborators,
The Sun maintains its low-to-moderate activity level. A few new
regions have shown significant growth in sunspot area during the past
24 hours: NOAA 14007 in the Southwest quadrant and NOAA 14009 in
the Northeast quadrant, but they both are not showing strong flare activity
yet. The largest event in the past 24 hours was a C6.4 event at 8:20 UT
today (3/1) from another new region, NOAA 14010 in the Northeast
hemisphere.
Yesterday's target, NOAA 14006 significantly reduced its size (350 to
180 millionths) and produced several low-to-mid C class flares during
its decay. This region maintains the jet activity seen in EUV 304A from
the area of leading sunspots. We will continue to observe the leading
sunspots of NOAA 14006 as a default target for another 24 hours,
expecting additional C class events.
The position of the target in NOAA 14006 on 1-March-2025 at
16:30 UT is: N18W17 (281", 420").

Dear Collaborators,
Solar activity continues to be at a low-to-moderate level. The largest
event in the past 24 hours was a C9.3 flare at 23:12 UT on 2/27 from
NOAA 13996 behind the Southeast limb. The target region NOAA
13998 produced 2 C class events and undergoing the limb passage
today.
NOAA 14006 is a region classified as a beta-gamma type (D-type),
currently transiting the North central meridian. Although no flare
activity is recorded in the past few days, its leading (positive)
area made of multiple sunspots is showing relative movements and
actively producing jets best seen in EUV 304A line. Today we will
observe the leading sunspots of NOAA 14006 as a default target,
expecting a few C class events.
The position of the target in NOAA 14006 on 28-February-2025 at
16:30 UT is: N19W05 (82", 430").
