Dear Collaborators,
Solar activity continues at low levels. The largest event
since the last message was a C3.0 flare at 23:20 UT on
30-Aug-2023 from NOAA 13413. 13413 was also the
source of a C1.5 flare and it retains its beta/D-type magnetic
configuration. Today the target shall switch to NOAA 13413.
Yesterday’s target NOAA 13417 (S05E39, beta/D-type) was
quiescent in the period. In addition, NOAA 13415 (S09W38,
beta/D-type) and two plage regions (S26W11, N17W49) also
produced a few low-C …
[View More]flares. B-class activities are expected
with low C-class flares probable in the next 24 hours.

Dear Collaborators,
Solar activity has been at low levels for the past 24 hours.
The largest event was a C4.0 flare at 23:17 UT on
29-Aug-2023 from NOAA 13417. 13417 also produced a
C1.7 plus a B9.9 flares. This region was classified as a
beta/C-type with mixed polarities in the leading portion.
Today the target region shall switch to NOAA 13417.
Yesterday’s target (still unnumbered, N21E81) was the
source of 2 C1 flares and 2 B-class flares but it has a low
and decreasing current helicity. In …
[View More]addition, NOAA 13413
(N09W43, beta/D-type) and NOAA 13415 (S10W26,
beta-gamma/D-type) also produced a C1.3 plus a B8.4
flares. Additional C-class activities are likely from various
active regions with a slight chance of a low M-class flare
in the following 24 hours.

Dear Collaborators,
Solar activity has increased since the last message.
The largest event was a C2.3 flare at 23:54 UT on
28-Aug-2023 produced by a northeast limb region
(unnumbered yet). This region was the most
flare-productive for the source of multiple low-C and
B-class events. Today the target region shall switch to
the limb region. Yesterday’s target NOAA 13413
(N10W32, beta-delta/D-type) only produced 3 C1 flares.
NOAA 13417 (S08E68, beta/D-type) and NOAA 13416
(S19E21, alpha/H-type) …
[View More]also produced several C1 flares.
More C-class activities are expected with a slight chance
of a low M-class flare in the next 24-hour period.

Dear Collaborators,
Solar activity continues at a very low level. The largest
event was a C1.0 flare at 03:54 UT today from NOAA
13405, which is almost rotating beyond the west limb.
Yesterday’s target (S05E89) was quiescent in the period.
NOAA 13413 on the disk retains its beta/D-type magnetic
configuration and has increased in sunspot area and
counts. Today the target region shall switch to NOAA 13413.
B-class activities are expected with low C-class flares
probable in the next 24 hours.

Dear Collaborators,
Solar activity has been at moderate-to-low levels. The largest
event was a long-duration M1.1 flare at 21:30 UT on
26-Aug-2023 from a southeast limb region (unnumbered yet).
Today the target region shall switch to this region. Yesterday’s
target (NOAA 13405) was only the source of a few low-C flares
with magnetic signs of decay. More C-class activities are
probable in the next 24 hours with a slight chance of another
low M-class flare.

Solar activity has decreased since the last message. The largest event
was a C5.0 flare at 15:40 UT on 25-Aug-2023 from NOAA 13405. This
region has been classified as a beta/C-type sunspot group, increasing
in magnetic complexity. It also produced a low-C flare plus two
B-class flares and continued to be the most flare-productive region.

and B-class flares. Additional C-class activities are expected from

Dear Collaborators,
Solar activity has reached a moderate level. The largest
event since the last message was a M1.5 flare at 00:56 UT
today from NOAA 13415. This region was still classified
as a beta/D-type configuration and emerged a new sunspot.
Today the target region shall switch to NOAA 13415.
Yesterday’s target (NOAA 13413) has been quiescent over
the period. Please note that NOAA 13405 (alpha/H-type,

Dear Collaborators,
Solar activity has returned to low levels since the last
message. Yesterday’s target (NOAA 13405) produced the
largest event, a C3.9 flare at 13:54 UT on 23-Aug-2023,
but it was downgraded to an alpha/H-type configuration.
NOAA 13413 was the most productive in the period. It
has been classified as a beta/F-type sunspot group and
increased in sunspot area and emerged new spots. Today
the target region will switch to NOAA 13413. In addition,

Dear Collaborators,
Solar activity has increased over the past 24 hours with
an M1.1 flare at 22:35 UT on 22-Aug-2023 produced by
NOAA 13405. This region also produced a C7.2 and
several low-C flares. It increased in the number of spots
and has been classified as a beta/C-type sunspot group.
Today the target region will switch to NOAA 13405.
Yesterday’s target was numbered as NOAA 13415
(alpha/H-type, S09E67) and was only the source of two
low C-class flares. Further C-class activities are …

Dear Collaborators,
Solar activity has reached an intermediate level. The largest event
since the last message was a C5.7 flare at 23:47 UT on 21-Aug-2023
from the target region. This region remains the highest frequency of
flaring and has also produced 5 low-C flares. It shows a high and
increasing current helicity. Today the target region shall continue at
this region. Please note that NOAA 13413 (N10E66, alpha/H-type)
