Dear Collaborators,
Solar activity has been at a moderate level. The largest event
since the last message was an M2.1 flare at 00:18 UT today
produced by the target NOAA 14043. 14043 also produced four
C-class flares (including a C7.0) during the period. It retains a
beta/D-type configuration but increases the sunspot area and
number of spots. More C-class activities are expected with a
good chance of another low M-class flare in the next 24 hours.
The position of NOAA 14043 on March 27 at 04:30 UT is:
N11E49 (-714", 255")

Dear Collaborators,
Solar activity has increased since the last message. There
produced an M1.0 flare at 07:44 UT (just an hour ago) by a
newly numbered region NOAA 14043. 14043 also produced
five low C-class flares and has been designated as a beta/D-type
region. Today the target will switch to NOAA 14043. Yesterday's
target NOAA 14036 (N08W81) was the source of nine low
C-class flares and it is rotating over the west limb. Further
C-class activities are expected from various regions, with
some chance of another low M-class flare from NOAA 14043
in the next few days.
The position of NOAA 14043 on March 26 at 08:30 UT is:
N13E50 (-719", 286")

Dear Collaborators,
Solar activity continues at a very low level. The target region
NOAA 14036 was the source of more than ten low C-class
flares over the past 24 hours, the largest one being a C3.4
flare at 00:36 UT today. 14036 retains a beta-gamma/D-type
configuration and is rotating over the west limb. Only C-class
activities are expected in the following 24 hours.
The position of NOAA 14036 on March 25 at 04:30 UT is:
N07W68 (886", 159")

Dear Collaborators,
Solar activity continues at a low level. The largest event
since the last message was a C5.2 flare at 07:25 UT today
produced by NOAA 14035 (N15W14) that has a beta/C-type
configuration. The target region NOAA 14036 was the source
of two C1.3 flares during the period. It retains a beta-gamma/
D-type configuration and shows an increasing current helicity.
Today we will continue to watch this region. C-class activities
are expected in the next 24 hours.
The position of NOAA 14036 on March 24 at 08:30 UT is:
N07W57 (802", 179")

Dear Collaborators,
Solar activity has been at a low level since the last message.
The largest event was a C5.0 flare at 17:11 UT yesterday(3/22) from
NOAA 14035, but more than 20 low-C class events were reported from
multiple sources in the past 24 hours.
Yesterday's target, NOAA 14036 produced only 3 class flares, but
reached 220 millionths in size and was classified as a beta-gamma
type. We will continue to observe NOAA 14036 at its central area
for the next 24 hours expecting additional C class events.
The position of the target in NOAA 14036 on 23-March-2025 at
15:30 UT is: N06W48 (718", 192").

Dear Collaborators,
Solar activity has been low since the last message. The largest event
was an isolated M1.2 flare at 15:24 UT yesterday(3/21) from NOAA 14028.
After this event, NOAA 14028 is losing its sunspot area. The target
region, NOAA 14031 did not produce any flare during the past 24 hours
and is approaching the Northwest limb.
NOAA 14036 is a region appeared in the Northwest quadrant yesterday.
This region has grown rapidly to over 100 millionths and produced 4
low-C class flares in the past 12 hours. Today we will switch the
default target to NOAA 14036 to observe its central area. Additional
C class flares are expected.
The position of the target in NOAA 14036 on 22-March-2025 at
15:00 UT is: N07W33 (528", 217").

Dear Collaborators,
Solar activity has been very low in the last 24 hours. The largest
event was a C4.4 flare at 16:49 UT yesterday (3/20) from NOAA 14025
approaching the West limb.
The target region, NOAA 14031 was flare-quiet only produced a C1.5
flare at 00:52 UT today. This region lost most of the trailing (negative)
sunspots, but new sunspots appeared in the Northeast of the leading
sunspot in the recent 12 hours. We will continue to observe NOAA
14031 for another 24 hours, at the area of the leading sunspot with
new flux emergence. C class events are expected.
The position of the target in NOAA 14031 on 21-March-2025 at
15:30 UT is: N16W61 (808", 326").

Dear Collaborators,
Solar activity has been at a low-to-moderate level since the last
message. Yesterday's target, NOAA 14031 was a source of an M1.5
flare at 20:21 UT on 3/19 as well as a C5.5 flare at 3:35 UT today
(3/20). There was a C6.0 event from NOAA 14018 at 23:14 UT on 3/19
associated with a filament eruption from the Southwest limb, but
this region is now completely behind the limb.
There is no significant flux emergence or dynamic movement of
sunspots observed on the visible side of the solar disk. We will
continue to observe the current target, the central area of NOAA
14031 for another 24 hours, expecting additional C class or low-M
class flares.
The position of the target in NOAA 14031 on 20-March-2025 at
15:30 UT is: N15W43 (641", 340").

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").
