Dear Collaborators,

Solar activity has continued at a moderate level in the past 24
hours. The largest event since the last message was an M3.6
flare at 07:24 UT today produced by NOAA 13753 (beta/D-type,
N12W29), a newly-emerged region. NOAA 13744 (beta/C-type,
N16W08) also produced an M1.4 flare and a C7.3 flare but it
shows signs of decay. NOAA 13751 became the most productive
region in the period and produced four high C-class flares including
the largest magnitude being a C9.4 flare at 22:23 UT yesterday.
This region has been classified as a beta-gamma/D-type magnetic
configuration, with new negative magnetic fluxes emerging in its
following portion. It also shows a high and increasing current helicity.
Today the Major Flare Watch region will switch to NOAA 13751
from NOAA 13738. Yesterday’s target (13738) was flare-quiet in
the period. Further C-class flares are expected with additional
low-M activity probable in the following 24 hours from various
active regions.

The position of NOAA 13751 at 11:30 UT on 16-Jul-2024 is:

S08E47 (-685", -181")
