Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13323 has
grown in number of spots and has been reclassified as a beta-gamma/
D-type spot group. This region continued being the source of C-class
flares since the last message, but the largest event in the period
was an M1.5 flare on 2-Jun-2023 at 02:32 UT from a small pore region
that is emerging flux close to central meridian. The target remains
with 13323 due to its magnetic complexity and past flaring history.
More high C-class flares are probable in the next 24 hours, with a
chance for an isolated M-class flare.
The position of NOAA 13323 on 2-Jun-2023 at 18:00 UT is:
S08E47 , ( -687", -126" )

Dear Collaborators,
The level of solar activity is moderate. The target region has now been
designated as NOAA 13323 and was classified as a beta/D-type spot group,
although an accurate magnetic classification was still affected by its
proximity to the limb at the start of the UT day. NOAA 13323 continued
its flaring activity since the last message, producing several C-class
flares and an M4.2 on 31-May-2023 at 22:14 UT - the largest magnitude
flare in the period. We remain with 13323 as the MM#009 Default Target,
but the magnetic complexity of this region will be monitored closely
for possible consideration of a MM#003 Major Flare Watch. Further high
C-class flares are expected over the following 24-hour period, with a
good chance of additional M-class activity.
The position of NOAA 13323 on 1-Jun-2023 at 18:00 UT is:
S05E58 , ( -801", -77" )

Dear Collaborators,
Solar activity is at a low-to-moderate level. Target region NOAA 13315
has regained its delta spot but continued to decay in size since the
last message, being now classified as a beta-gamma/E-type spot group.
A new mature spot region is in the process of rotating over the South
East limb and has already become the most flare-productive region with
being the source of multiple C-class flares and an M1.3 on 31-May-2023
at 04:24 UT. The target will now switch to this currently unnumbered
limb region. Additional C-class activity is expected in the next 24
hours, with a good chance of further M-class flaring.
The approximate position of this region on 31-May-2023 at 21:00 UT is:
S06E90 , ( -941", -99" )

Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13315 has shown
further signs of decay since the last message, decreasing in spot area and
magnetic complexity to be a beta-gamma/E-type sunspot group. In the period
NOAA 13310 produced several C-class flares and two M-class flares (an M1.2
and M1.3 on 30-May-2023 at 07:54 UT and 10:15 UT, respectively) during its
approach to the South West limb. NOAA 13315 has also continued to be flare
active, being the source of C-class activity and an M1.5 on 30-May-2023 at
13:35 UT - the target remains as NOAA 13315. Further C-class flares are
expected over the following 24-hour period, with a chance for additional
low M-class flares.
The position of NOAA 13315 on 30-May-2023 at 18:00 UT is:
S16W44 , ( 632", -251" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13315 has
decayed slightly since the last message, but continues to be
classified as a beta-gamma-delta/E-type sunspot group. Despite
this, NOAA 13315 remained the most flare-productive of the spot
regions, being the source of four C-class flares in the period.
Additional C-class activity is expected in the next 24 hours,
with a chance for an isolated low M-class flare.
The position of NOAA 13315 on 29-May-2023 at 16:30 UT is:
S17W31 , ( 468", -264" )

Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13315
grew further in spot area and magnetic complexity since the last
message, now classified as a beta-gamma-delta/E-type spot group.
This region remained the most flare productive region, being the
source of several C-class flares and the largest magnitude flare
in the period - an M1.0 on 28-May-2023 at 10:21 UT. Additional
C-class flares are expected over the following 24-hour period,
with a good chance for another low M-class flare.
The position of NOAA 13315 on 28-May-2023 at 16:30 UT is:

Dear Collaborators,
Solar activity is at a low-to-moderate level. Target NOAA
13315 grew in spot area and number of spots since the last
message but remains classified as a beta/D-type spot group.
NOAA 13315 continued to be the most flare productive region
on the visible disk, being the source of C-class activity
and the largest magnitude flare in the period - an M1.4 on
26-May-2023 at 22:48 UT. C-class activity is expected in
the next 24 hours, with a chance for another M-class flare.

Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13311
has decayed further since the last message but remains classified
as a beta-gamma/E-type spot group. NOAA 13315 is in a continued
period of magnetic flux emergence and has become the most flare
productive region on the visible disk, producing multiple C-class
flares that includes the largest magnitude flare in the period -
a C3.0 flare on 26-May-2023 at 16:56 UT. At this time we terminate
the MM#003 Major Flare Watch, while the nominal target switches to
NOAA 13315. C-class flares are expected over the following 24-hour
period, with low M-class activity also possible.
The position of NOAA 13315 on 26-May-2023 at 18:00 UT is:
S16E09 , ( -145", -241" )

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13311 has
decayed slightly since the last message, losing its magnetic delta
and being classified as a beta-gamma/E-type spot group. NOAA 13311
remained the most flare productive region on the visible disk with
producing multiple C-class flares and an M1.8 flare on 24-May-2023
at 17:04 UT that was the largest magnitude flare in the period. The
MM#003 Major Flare Watch on NOAA 13311 will continue over the next
24 hours because of its own complexity and nearby NOAA 13314 having
emerged flux to form new trailing spots that are opposite polarity
and in close proximity to the leading spots of NOAA 13311. More low
M-class flares are likely in the next 24 hours, with a small chance
for another >M5 flare.
The position of NOAA 13311 on 25-May-2023 at 18:00 UT is:
N18W18 , ( 277", 316" )

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13311 has
grown in size since the last message and has been reclassified as a
beta-gamma-delta/F-type spot group. This region continues to be the
most flare productive active region, generating multiple C-class
flares and an M1.0 on 24-May-2023 at 09:51 UT that was the largest
magnitude flare in the period. The MM#003 Major Flare Watch on NOAA
13311 will remain in effect for at least a further 24 hours. More
low M-class flares are probable over the following 24-hour period,
with a chance for another >M5 flare.
The position of NOAA 13311 on 24-May-2023 at 15:30 UT is:
