Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13100 has been stable in terms of spot area and number of spots since the last message, remaining classified as a beta/C-type sunspot group. This region was flare-quiet in the period, while previous target NOAA 13098 increased in magnetic complexity to become a beta-gamma/E-type sunspot group and returned to C-class flaring. The recently numbered NOAA 13101 in the North West quadrant has also increased in structural complexity to be classified as a beta/D-type sunspot group and has been the source of multiple C-class flares since the last message, including the largest of the period - a C7.4 on 12-Sep-2022 at 12:55 UT. The target will switch to NOAA 13101 because of its recent higher frequency of flaring compared to NOAA 13098. Further high C-class flares are expected over the following 24-hour period, with a good chance for an M-class flare.

The position of NOAA 13101 on 12-Sep-2022 at 15:00 UT is:

N29W79 , ( 819", 439" )
