Dear Collaborators,
Solar activity has slightly decreased since the last message. The
largest event during the period was an M2.5 flare at 22:18 UT
yesterday, produced by the target region NOAA 14048 (S16E33).
This region retains a beta-gamma-delta configuration and produced
ten additional C-class flares, including a C8.1 flare at 10:39 UT
today. Given its magnetic complexity, ongoing flux emergence,
and activity history, we will continue to watch this region with a
Major Flare Watch campaign for the next 24 hours. Low M-class
activity is expected, with a chance of an isolated >M5 flare in the
next 24-48 hours.
The position of NOAA 14048 on 2-Apr-2025 at 11:30 UT is:
S16E33 (-504",-176")

Dear Collaborators,
Solar activity has been at a high level since the last message.
The largest event in the period was an M5.6 flare at 06:37 UT
today, produced by NOAA 14046 (N05E24). This region retains
a beta-gamma configuration and produced another three C-class
flares. The target region NOAA 14048 (S16E46) has developed
into a beta-gamma-delta configuration with further increases in
both spot area and number. It remained the most flare-productive
region in the period, producing an M1.3 flare and over ten C-class
flares. The Major Flare Watch will remain effective with NOAA
14048 as the target region due to its magnetic complexity and
continued flux emergence in its intermediate portion. Further low
M-class flares are expected from the target region and also from
NOAA 14046, with a chance of an additional flare exceeding M5
in the next few days.
The position of NOAA 14048 on 1-Apr-2025 at 11:30 UT is:
S16E46 (-665",-190")

Dear Collaborators,
Solar activity has slightly increased since the last message.
NOAA 14048 (S15E59) remained the most flare-productive
region in the period, producing over ten C-class flares and
five low M-class flares, including the largest—an M1.6 at
16:27 yesterday. This region has developed into a beta-gamma
configuration with increases in both spot area and number.
14048 is undergoing significant magnetic flux emergence in
its intermediate portion. Today, the Major Flare Watch shall
switch to this region. Yesterday's target NOAA 14046 (N05E39)
has also increased in magnetic complexity to a beta-gamma
configuration and produced a C7.6 flare in the period. Further
low M-class activity is expected from the target region and also
from NOAA 14046, with a chance of an above M5 flare in the
next few days.
The position of NOAA 14048 on 31-March-2025 at 07:30 UT is:
S15E59 (-796",-192")

Dear Collaborators,
Solar activity has been at a moderate level. The largest event
over the past 24 hours was an M1.9 flare at 22:38 UT yesterday
produced by a newly numbered region NOAA 14048 (S15E75).
14048 also produced another two low M-class flares (M1.4 and
M1.5) and 13 C-class flares. This region was designated as a
beta/D-type configuration and has a highest current helicity
compared with the other active regions. The target region
NOAA 14046 only produced two low C-class flares during the
period. It retains a beta/C-type configuration. Considering that
it has a largest sunspot area of 270 uh and shows some new
flux emergence, today we continue to watch this region with
a Major Flare Watch campaign for another 24 hours. Further
low M-class activities are expected from the target region and
also from NOAA 14048, with some chance of a >M5 flare in
the next few days.
The position of NOAA 14046 on March 30 at 04:30 UT is:
N05E54 (-775", 148")

Dear Collaborators,
Solar activity has significantly increased since the last message.
An X1.1 flare (at 14:57 UT yesterday, accompanied by a CME)
was produced by a newly numbered region NOAA 14046 near
the northeast limb. This region also produced an M1.0 flare at
17:54 UT after the X-class flare. At this time we are implementing
the Major Flare Watch campaign on NOAA 14046. 14046 was
designated as a beta/C-type configuration but had a sunspot
area of 270 uh. Please note that another region NOAA 14045
(S15E60, alpha/H-type) was the source of two M-class (M1.1
and M1.8) and three low C-class flares during the period.
Additional low M-class activities are expected with a chance
of a major flare above M5 in the next 24 hours.
The position of NOAA 14046 on March 29 at 04:30 UT is:
N05E66 (-875", 128")

Dear Collaborators,
Solar activity has decreased a little bit since the last message.
The largest event during the period was a C8.8 flare at 22:41 UT
yesterday produced by the target NOAA 14043. 14043 also
produced another four C-class flares including a C7.5. It retains
a beta/D-type configuration and shows some mixed polarities in
its intermediate portion. Today we will continue to watch this
region. Further C-class activities are expected with some chance
of a low M-class flare in the next 24 hours.
The position of NOAA 14043 on March 28 at 08:30 UT is:
N14E23 (-365", 332")

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:

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:

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:

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.
