Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13429 has been stable in terms of spot area and number of spots since the last message. Its development of a delta configuration late yesterday was confirmed through its designation as a beta-gamma-delta/D-type group. NOAA 13429 produced nearly every C-class flare in the period and all of the three M-class flares that occurred, the largest being an M3.3 on 16-Sep-2023 at 05:28 UT. We are NOT starting an MM#003 Major Flare Watch at this point mainly because NOAA 13429 has not undergone fresh flux emergence - this region will be monitored closely in case this changes. C-class flares are expected in the following 24-hour period, with a strong chance for more low-to-mid M-class flares.

The position of NOAA 13429 on 16-Sep-2023 at 20:00 UT is:

N11W20 , ( 322", 71" )
