Dear Collaborators,
Solar activity has slightly increased since the last message. NOAA
13842 was the source of an X7.1 flare at 21:58 UT yesterday. This
region continues to show dynamic sunspot activity and has increased in
area to 300 ÎĽh. The Major Flare Watch will continue with NOAA 13842 as
the target region. Further M-class activity is possible with a chance
for an additional >M5 event in the next 24-48 hours.
The position of NOAA 13842 on 2-October-2024 at 11:30 UT is:
S15E11, (-177",-352")

Dear Collaborators,
Solar activity continues at a moderate level. A number of flares were
produced over the last 24 hours, the largest being an M7.7 from NOAA
13842 at 23:37 UT yesterday. NOAA 13842 remains classified as a
beta-gamma-delta and has shown significantly elevated sunspot dynamism
since the last message. This region also shows signs of significant
flux. At this time we are initiating a Major Flare Watch with NOAA
13842 as the target region. Further C- and M-class activity is
expected, with a chance for further isolated >M5 activity in the next
24 hours.
The position of NOAA 13842 on 1-October-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity remains moderate. Several flares were produced over the
last 24 hours, the largest being an M1.8 from NOAA 13842 at 14:09 UT
yesterday. NOAA 13482 has now developed into a beta-gamma-delta type
region with a sunspot area of 230 ÎĽh. Currently, NOAA 13482 shows
steady sunspot behaviour, however the development of this region
should be closely monitored over the next 24 hours. Further C-class
activity is expected, with a chance for additional M-class activity in
the next 24 hours.
The position of NOAA 13842 on 30-September-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity continues at a moderate level. The largest event
since the last message was an M1.0 flare at 12:49 UT today
from an unnumbered region (S10E23), which emerged a
bipolar sunspot group. This M1.0 flare was superimposed on
the gradual phase of a long-duration C5.6 flare at 07:46 UT
produced by a region currently beyond the South East limb
(N14E88). The eastern part of the target region has been
renumbered as NOAA 13842 and has been confirmed as a
beta-gamma/D-type sunspot group, with an area of 220 MSH.
Today the default target region will remain with NOAA 13842
due to its overall size and prior flaring history. Further C-class
activities are expected, with a chance of another low-M flare
in the next 24 hours.
The position of NOAA 13842 on 29-Sep-2024 at 11:30 UT is:
S14E50 (-713", -301")

Dear Collaborators,
Solar activity has returned to a low level in the past 24 hours.
The target region NOAA 13839 was still the most productive
region. It was the source of five C-class flares, with the largest
magnitude being a C6.3 at 14:14 UT yesterday. 13839 has
been reclassified as a beta/F-type magnetic configuration as
it rotates further onto the solar disk. In addition, NOAA 13836
(S12E11, beta-gamma/D-type) and NOAA 13835 (S22W06,
beta/D-type) also produced three C3 flares. Further C-class
activities are expected, with a low-M flare likely in the next
24 hours.
The position of NOAA 13839 on 28-Sep-2024 at 11:30 UT is:
S14E56 (-771", -292")

Dear Collaborators,
Solar activity continues at a moderate level. The largest
event since the last message was an M1.4 flare at 22:58 UT
yesterday produced by the previous limb region. This region
also produced an M1.0 flare plus eight C-class flares, numbered
as NOAA 13839. It has been classified as an alpha/H-type
configuration but its proximity to the limb hampers accurate
classification. 13839 should become the new target due to its
current level of flaring. Yesterday’s target region NOAA 13836
(S10E24, beta-gamma/D-type) only shows some brightenings
in EUV images. Further C-class activities are expected, with a
chance of an isolated low-M flare in the next 24 hours.
The position of NOAA 13839 on 27-Sep-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has increased to a moderate level. Three regions
produced >C5 flares since the last message. NOAA 13828
(S11W55, alpha/H-type) produced the largest event - an M1.3
flare at 22:57 UT yesterday. An unnumbered region near the
South East limb (S12E82) was also the source of a C5.2 flare
at 11:50 UT today. NOAA 13836 produced a long-duration C9.6
flare at 14:41 UT yesterday. It retains a beta-gamma/D-type
magnetic configuration and became the most productive region.
Today's target region shall switch to 13836 because of its high
magnetic complexity and flaring productivity. Yesterday’s target
region NOAA 13835 (S22E17, beta-gamma/D-type) has been
flare quiet in the period. Further C-class activities are expected,
with another low-M flare probable in the following 24-48 hours.
The position of NOAA 13836 on 26-Sep-2024 at 11:30 UT is:
S10E38 (-582", -255")

Dear Collaborators,
Solar activity has dropped to a low level. The target region
NOAA 13835 only produced a C2.4 flare at 14:01 UT yesterday.
However, 13835 has again experienced the emergence of
new magnetic fluxes in its intermediate portion since the last
message, remaining a beta/D-type sunspot group. 13835
shall continue as the target. In addition, NOAA 13833 (N22W60,
beta/C-type), NOAA 13828 (S11W41, alpha/H-type) and NOAA
13836 (S10E52, beta-gamma/D-type) also produced a few
low-C flares, with the largest two being a C4.0 at 07:27 UT
and a C3.7 at 10:07 UT today from 13836. Additional C-class
activities are expected in the next 24 hours.
The position of NOAA 13835 on 25-Sep-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has returned to a moderate level. The largest
event was an M1.4 flare at 14:23 UT yesterday from NOAA
13836 (S12E65, beta-gamma/D-type). A spotless region
(S16W21) near NOAA 13828 also produced a C6.9 flare at
11:29 UT today. The target region NOAA 13835 was the
source of a C6.5 flare at 03:33 UT today. This region retains
its beta/D-type magnetic configuration and it continues to
emerge new spots. Today the target region should remain with
NOAA 13835. Further C-class activities are expected, with a
chance of another low-M flare in the coming 24 hours.
The position of NOAA 13835 on 24-Sep-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has been at a moderate-to-low level. The largest
event since the last message was an M3.8 flare at 21:12 UT on
22-Sep-2024 from NOAA 13835. This region emerged yesterday
and has been classified as a beta/D-type sunspot group. 13835
shall become the new target. Yesterday’s target NOAA 13831
only produced a C3.7 flare at 13:18 UT on 22-Sep-2024. Besides,
the other three low-C flares are produced by two active regions
(NOAA 13828 and 13825) and an unnumbered region from the
South East limb (S16E87). More C-class flares are expected,
with M-class activity likely in the following 24 hours.
The position of NOAA 13835 on 23-Sep-2024 at 11:30 UT is:
