Dear Collaborators,
Solar activity has increased since the last message. The largest
event during the period was an M3.5 at 03/16/16:22 UT produced
by a southeast limb region. This limb region also produced an
M1.2 flare at 03/16/21:27 UT and nine C-class flares (including
a C8.2). Today we will switch the target to this limb region.
Yesterday's target, the northeast limb region (N15E86), produced
four low C-class flares. More C-class activities are expected from
these two limb regions, with a chance of additional M-class flares
in the next few days.
The approximate position of the target on March 17 at 12:30 UT is:
S15E87 (-940", -230")

Dear Collaborators,
Solar activity has been at a very low level since the last message.
The largest event during the period was a C1.8 flare at 12:01 UT
yesterday produced by yesterday's target region NOAA 13599.
13599 has now completely rotated over the west limb. A new region
near the northeast limb generated a C1.4 flare late yesterday, which
is rotating onto the visible disk. Today the target will switch to this
limb region. Additional C-class activities are expected in the next
24-hour period.
The approximate position of the target on March 16 at 08:30 UT is:
N15E90 (-920", 280")

Dear Collaborators,
Solar activity has been at a relatively low level since
the M1.0 flare yesterday. The largest event during the
period was a C6.0 flare at 05:31 UT today from the
target region NOAA 13599. 13599 also produced six
low C-class flares and its overlying loops are still visible
above the limb. We will watch this region for another
24 hours. Further C-class activities are expected in the
following 24 hours.
The position of NOAA 13599 on March 15 at 08:30 UT is:
S13W91 (939", -217")

Dear Collaborators,
Solar activity has increased for the past 24 hours. The largest
event since the last message was an M1.0 flare at 05:52 UT
today, produced by the target region NOAA 13599. 13599 also
produced six C-class flares (including a C6.2) and four high
B-class flares during the period. This region was designated
as a beta/C-type configuration as it is almost rotating over the
west limb. We will watch this region for the next 24 hours.
Additional C-class activities are expected in the following 24-
hour period.
The position of NOAA 13599 on March 14 at 08:30 UT is:
S14W86 (933", -223")

Dear Collaborators,
Solar activity continues to be at low levels. The largest event
since the last message was a C3.9 flare at 03/12/11:14 UT
produced by the target region NOAA 13599. 13599 also
produced another nine low C-class flares during the period.
It retains a beta-gamma-delta/D-type configuration and is
rotating to the west limb. At this moment we end the Major Flare
Watch campaign with the default target still on NOAA 13599.
Further C-class activities are expected in the next 24 hours.
The position of NOAA 13599 on March 13 at 08:30 UT is:
S12W74 (908", -166")

Dear Collaborators,
Solar activity continues at a low level. The largest event
since the last message was a C2.6 flare at 04:01 UT today
produced by the target region NOAA 13599. 13599 also
produced another eight ~C1 flares and three high B-class
flares in the period. This region retains a beta-gamma-delta/
D-type configuration with decreasing in the sunspot area
and number of spots slightly. But it is still showing some
new spots in its intermediate portion. Considering that its
current helicity remains at a high level, we will continue the
Major Flare Watch on this region probably for the final
24 hours. C-class activities are expected with some chance
of an isolated flare above M5 in the next 24 hours.
The position of NOAA 13599 on March 12 at 08:30 UT is:
S12W60 (819", -140")

Dear Collaborators,
Solar activity has been at a low level since the last message.
The largest event during the period was a C5.8 at 08:36 UT
today produced by target region NOAA 13599. 13599 retains
its beta-gamma-delta/D-type configuration and it seems to
continue emerging new magnetic fluxes especially in its trailing
portion. Today we will continue the Major Flare Watch campaign
on this region. An isolated flare above M5 is still likely in the
next 24-48 hours.
The position of NOAA 13599 on March 11 at 08:30 UT is:
S13W46 (678", -133")

Dear Collaborators,
The level of solar activity is moderate-to-high. Target region NOAA
13599 has undergone another period of magnetic flux emergence since
the last message, growing in spot area and regaining a delta-spot
configuration to be classified as a beta-gamma-delta/D-type sunspot
group. NOAA 13599 continued as the most flare-productive region on
disk with being the source of four C-class flares and the largest
magnitude flare in the period, an M7.4 on 10-Mar-2024 at 12:00 UT.
At this point we are initiating a MM#003 Major Flare Watch on NOAA
13599 due to its recent growth and flare productivity. Additional
C-class activity is expected over the following 24-hour period,
with a good chance for another flare >=M5.
The position of NOAA 13599 on 10-Mar-2024 at 16:30 UT is:
S13W38 , ( 581" , -122" )

Dear Collaborators,
Solar activity is at a low-to-moderate level. Target region NOAA
13599 has maintained spot area since the last message, but lost
the delta configuration to be classified as a beta-gamma/D-type
sunspot group. NOAA 13599 continued to produce most flares in
the period in the form of several C-class flares as well as the
largest magnitude flare, an M1.3 on 8-Mar-2024 at 21:18 UT. More
C-class flares are expected in the next 24 hours, with a chance
for another M-class flare.
The position of NOAA 13599 on 9-Mar-2024 at 16:30 UT is:
S12W25 , ( 400" , -91" )
