Dear Collaborators,
Solar activity has slightly reduced since the last message. A number
of flares were produced, the largest being an M1.6 attributed to NOAA
13839 (this may also be associated with NOAA 13842) at 20:52 UT today.
Since the last message, NOAA 13842 has continued its approach of the
southwest limb. At this time, this region still shows signs of strong
flux, however the associated spot activity appears relatively stable.
The Major Flare Watch will be extended for what may be the final 24
hours as NOAA 13842 embarks on its transit of the southwest limb.
Additional C- and M-class activity is expected with a small chance for
an isolated >M5 event in the next 24 hours.
The position of NOAA 13842 on 7-October-2024 at 11:30 UT is:
S16W57, (775",-319")

Dear Collaborators,
Solar activity remains at a moderate-high level. Several flares were
produced, the largest being an M2.4 from NOAA 13842 at 23:10 UT
yesterday. While no large flares were produced in the last 24 hours,
NOAA 13842 has continued to grow in area, reaching 1040 μh as it
begins its transit of the southwest limb. Significant flux is present
surrounding this region. The Major Flare Watch will be extended while
NOAA 13842 remains on the disk. Further C- and M-class activity is
expected, with a chance for an isolated >M5 event in the next 24-48
hours.
The position of NOAA 13842 on 6-October-2024 at 11:30 UT is:
S14W42, (624",-308")

Dear Collaborators,
Solar activity has continued at a moderate-high level. Several flares
were produced over the last 24 hours, the largest being an M1.2 from
NOAA 13485 at 22:04 UT yesterday. NOAA 13842 has now reached an area
of 710 μh and continues to show significant sunspot dynamism. Equally,
NOAA 13844, another beta-gamma-delta region, has shown significant
development in the last 24-48 hours, reaching an area of 660 μh and
also showing very dynamic sunspot behaviour. Both of these regions are
approaching the southwest limb. The Major Flare Watch will remain
active with NOAA 13842 as the target region, but close attention
should also be paid to NOAA 13844.
The position of NOAA 13842 on 5-October-2024 at 11:30 UT is:
S14W29, (452",-323")

Dear Collaborators,
Solar activity remains at a moderate-high level. The largest flare of
the last 24 hours was an M6.7 from NOAA 13843 at 20:09 UT yesterday.
NOAA 13842 did not produce another flare since the last message.
However, this region is still classified as a beta-gamma-delta and now
has an area of 530 μh, while showing continual sunspot development.
The Major Flare Watch will remain active with NOAA 13842 as the target
region. Close attention should also be paid to NOAA 13843 and 13844 as
these regions have developed in complexity.
The position of NOAA 13842 on 4-October-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has reached a high level. NOAA 13842 produced an X9.0
at 12:08 UT today as well as several M-class flares. NOAA 13842 has
grown in area, now reaching 380 μh. This region also continues to show
significant sunspot dynamism and flux. The Major Flare watch will
remain active. Further C- and M-class activity is expected, with a
chance for an additional >M5 event in the next 24-48 hours.
The position of NOAA 13842 on 3-October-2024 at 11:30 UT is:

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 μh. 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:

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 μh. 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")
