Dear Collaborators,
Solar activity has remained at low levels since the last message, with only B-class flares reported during the period. The largest events were two B8.5 flares at 23:06 UT yesterday and 11:44 UT today from NOAA 14521 (N09W88, alpha/H-type), which is now close to the west limb. The target region NOAA 14530 (N19W44, beta/D-type) produced three B-class flares, including a B7.8 at 11:40 UT today. This region continues to show dynamic sunspot behaviour. Today, the target will remain at NOAA 14530. NOAA 14524 (N12W49, alpha/H-type) also produced two B-class flares during the period, including a B7.8. If possible, please continue to include NOAA 14524 in the field of view. C-class activity remains possible in the next 24 hours.
The position of NOAA 14530 on September 12 at 15:30 UT is:
N19W44 (627",226")
