Dear Collaborators,
Solar activity has been at a low level. The largest event in the
period was a B9.3 flare at 6:21 UT today (10/4) produced by NOAA
14546 in the Southwest quadrant. This event is very compact and
the region is reducing the area as it approaches the limb.
The target region, NOAA 14545 produced 3 mid-B class events in the
period, the largest being a B4.9 at 23:59 UT yesterday. NOAA 14545
maintains its spots surrounded by a larger plage. Today the target
continues to be NOAA 14545, at the area of trailing sunspots.
The activities of low-C class are expected.
The position of the target in NOAA 14545 on 4-October-2026 at
16:00 UT is: N20E25 (-394", 234").

Dear Collaborators,
Solar activity remains very low. GOES X-ray (1-8A) background stays
at a B2 level, the largest event reported in the period was a B5.0
at 14:59 UT today (10/3) from the target region, NOAA 14545.
NOAA 14545 maintains the magnetic complexity of a bata type, with
new flux emergence at the area of trailing sunspots. Today we will
continue to observe NOAA 14545, expecting low-C class events from
the area of trailing spots.
The position of the target in NOAA 14545 on 3-October-2026 at
16:00 UT is: N19E38 (-568", 240").

Dear Collaborators,
Solar activity continues to be at a very low level. The largest event
in the period was a C1.5 flare at 21:20 UT yesterday (10/1) from the
Northeast limb region, mentioned yesterday and now assigned the number
NOAA 14545, classified as a beta type. The target region, NOAA 14535
produced only a few low-B class events and will undergo its limb
transit in the next 24 hours.
Today we will switch the target to NOAA 14545 to observe the area of
its trailing sunspot where the C1.5 flare was produced. Additional
activity of low-C class is expected.
The position of the target in NOAA 14545 on 2-October-2026 at
16:00 UT is: N20E54 (-725", 277").

Dear Collaborators,
Solar activity has been very low since the last message.
The largest event in the period was a B7.8 at 12:41 UT today (10/1).
Two regions appear to have contributed to this event, one is NOAA
14535 at a plage in the North of the sunspot, the other is a plage
close to the Northeast limb at the latitude ~20 degree North. The
latter region holds tiny sunspots and is the source of a B5.0 event
at 2:26 UT.
Today we will continue to observe NOAA 14535, but the target will
be a plage in the North of the main sunspot. High-B to low-C class
events are expected.
The position of the target in NOAA 14535 on 1-October-2026 at
16:00 UT is: N14W64 (838", 186").
