Dear Collaborators,
Solar activity has slightly increased since the last message. Newly
numbered active region, NOAA 14079, has traversed onto the disk from the
northeastern limb and was the site of an M1.7 flare and several additional
C-class flares over the last 24 hours. Currently this region is classified
as a beta-type region but more may become apparent as this region
progresses further onto the disk. Imaging suggests a pair of large sunspots
to be within close proximity to each other that may evolve further in the
next 24-48 hours. NOAA 14079 will be the new target region, with a chance
for further isolated M-class events in the next 24 hours.
The position of NOAA 14079 on 29-April-2025 at 11:30 UT is
N08E67 (-869", 160")

Dear Collaborators,
Solar activity remains at a very low level. A small number of flares were
produced in the last 24 hours, the largest being a C2.3 at 05:46 UT today
attributed to NOAA 14067. NOAA 14064 has remained quiet, producing only two
flares since the last message. This region continues to reduce in sunspot
area but retains its beta type configuration. NOAA 14064 will continue as
the target region, with minor C-class activity expected in the next 24
hours.
The position of NOAA 14064 on 28-April-2025 at 11:30 UT is
N12W79 (915", 211")

Dear Collaborators,
Solar activity continues to be at a very low level with the GOES
soft X-ray flux flat at ~C1. Only two C1 flares (C1.2 and C1.3)
were produced by NOAA 14075 (S11E27, now a plage region)
and a region near the southeast limb (S18E88). The target region
NOAA 14064 was flare quiet since the last message. It retains
a beta/D-type configuration but significantly decreases the sunspot
area and number of spots as it is rotating to the west limb. Today
we will continue to watch this region for another 24 hours. Only
C-class activities are expected in the next 24 hours.
The position of NOAA 14064 on April 27 at 11:30 UT is:
N12W66 (852", 227")

Dear Collaborators,
Solar activity continues to be at a very low level for the past 24
hours. The largest event during the period was a C1.7 flare at
10:56 UT produced by the target region NOAA 14064. 14064 also
produced another two C1 flares and has been designated as a
beta/D-type configuration. Today we will continue to watch this
region as it seems to show some new flux emergence. Note that
another region NOAA 14073 (N12E19, beta/D-type) also produced
three C1 flares. Additional C-class activities are expected in the
next 24 hours.
The position of NOAA 14064 on April 26 at 15:30 UT is:

Dear Collaborators,
Solar activity has been very low since the last message. The largest
event in the past 24 hours was a C3.0 flare at 03:57 UT today (4/25)
from an unnumbered region rotated from the Southeast limb at the
latitude of ~17 deg.
Yesterday's target, NOAA 14064, was a source of 3 C class events
occurred at the period 14-16 UT yesterday. This region is flare-
quiet since then, but maintains the brightenings of the loops
connected to the filament extending to a Southeast direction.
Today we will continue to observe NOAA 14064, at the Eastern edge
of the trailing (negative) sunspot, which is the area connecting
to the filament. Additional C class events are expected.
The position of the target in NOAA 14064 on 25-April-2025 at
16:00 UT is: N12W35 (541", 275").

Dear Collaborators,
Solar activity continues to be low but slightly increased since the
last message. The largest event was a C3.8 flare at 00:20 UT today
(4/24) from NOAA 14064, which produced 2 more low-C class flares.
Other C class events were mainly from NOAA 14070, which increased
both in size and magnetic complexity (to a beta-gamma type), and
produced 7 low-C class flares. There was no report of flares from
the target region, NOAA 14062 in the recent 24 hours.
NOAA 14064 is undergoing new flux emergence in the West vicinity
of the trailing (negative) sunspot today. The EUV loops from this
region frequently interact with a filament located at the Southeast
of this region, and with a plage region around NOAA 14067.
Today, we will switch our target to NOAA 14064, to observe the area
of new flux emergence. Additional C class events are expected.
The position of the target in NOAA 14064 on 24-April-2025 at
15:30 UT is: N10W26 (420", 236").

Dear Collaborators,
Solar activity has been very low since the last message. The largest
event was a C2.6 flare at 18:51 UT yesterday (4/22) from the target
region, NOAA 14062. Other low C class events were from multiple
regions including NOAA 14068, 14064, and newly emerged 14070.
Today, we will continue to observe NOAA 14062, at the North side of
the main (negative) sunspot for another 24 hours. Additional C class
events are expected.
The position of the target in NOAA 14062 on 23-April-2025 at
15:30 UT is: S01W39 (606", 34").

Dear Collaborators,
Solar activity has increased to a low-to-moderate level since
the last message. There were 2 M-class flares reported in the
past 24 hours. One is an M1.9 flare at 18:24 UT yesterday(4/21)
from NOAA 10462, the other is an M1.3 flare at 9:58 UT today
from 14060 over the West limb. Several C class flares were
reported from multiple regions, but yesterday's target, now
assigned the NOAA number 14068 has been flare-quiet for more
than 24 hours. NOAA 14064 is undergoing notable new flux
emergence at the Northeast vicinity of the trailing (negative)
sunspot but not showing the flare activity yet.
NOAA 14062 reduced its magnetic complexity to a beta type, and
increased the number of spots by fragmentation. The M1.9 event
yesterday as well as the C1.7 event today was observed from the
North side of the main (negative) sunspots. Today, we will switch
the default target to NOAA 14062. We will observe the North side
of the main sunspot, expecting additional C class events.
The position of the target in NOAA 14062 on 22-April-2025 at
16:00 UT is: S01W25 (412", 58").

Dear Collaborators,
Solar activity has slightly increased from the last message
but still is at a low level. The largest event in the last
24 hours was a C4.3 event at 17:02 UT yesterday from NOAA
14063 approaching the West limb. Several low-C class events
were reported from multiple regions, like NOAA 14064, 14062
and a bright plage rotated from the Northeast limb.
The target region, the source region of two M class flares
(M4.5 on 4/18 and M1.0 on 4/20) from behind the Southeast limb,
is still unnumbered but appears to be a compact region formed
by 3 small sunspots. This region only produced a low C class
flare in the past 24 hours, but maintains rapid intensity
fluctuations in EUV wavelengths. We will continue to observe
this region for another 24 hours. C class flares are expected,
with a slight chance of an isolated low M class event.
The position of the target on 21-April-2025 at 16:00 UT is:
S26E66 (-783", -398").

Dear Collaborators,
Solar activity on the visible side of the disk continues to be
very low. However, there was another M class flare (M1.0 at
11:39 UT today, 4/20) observed from the Southeast limb region.
The largest event on the disk in the past 24 hours was a C4.3
flare at 16:23 UT yesterday from NOAA 14065. There was no
flare reported from the target region, NOAA 14064.
The source region of the M flare is currently under limb passage.
The sunspot is not visible but brightness in EUV wavelengths
started to be apparent. Today, we will switch the default target
to this unnumbered Southeast limb region. A few C class to
low-M class flares are expected.
The position of the target on 20-April-2025 at 15:30 UT is:
S25E88 (-864", -399").
