Dear Collaborators,
Solar activity has remained at low levels since the last message. The largest event during the period was a C1.4 flare at 00:25 UT today from NOAA 14524 (N12W20, alpha/H-type), with coronal brightenings indicating magnetic connectivity with the target region NOAA 14530 (N19W14, beta/D-type). Although the magnetic polarities of 14530 remain relatively diffuse, this region is now showing clear signs of magnetic flux emergence. Today, we will continue to watch NOAA 14530 as the target region due to this ongoing flux emergence and its magnetic connectivity with NOAA 14524. If possible, please include NOAA 14524 in the field of view. Further C-class activity is expected in the next 24 hours.
The position of NOAA 14530 on September 10 at 11:30 UT is:
N19W14 (218", 198")
