Dear Collaborators,
Solar activity has been low since the last message. The largest event in the period was a C1.4 flare at 18:26 UT yesterday(10/20) produced by NOAA 14551 from the plage region in the south of the leading sunspots. NOAA 14551 produced another C class flare (C1.3 at 10:51 UT today), but the observation will be limited because of its limb transit today. NOAA 14560, a new region emerged in the NorthEast of NOAA 14557, is showing steady growth but no flare is reported during the last 36 hours.
The target region, NOAA 14557 produced several high-B class flares in the last 24 hours, the largest being a B9.9 at 4:45 UT today. This region undergoes some new flux emergence from the central area, now reclassified as a beta-gamma type. In the next 24 hours, we will continue to observe NOAA 14557, at the Northern following sunspots showing mixed polarity. C-class events are expected.
The position of the target in NOAA 14557 on 21-October-2026 at 15:30 UT is: N07W48 (712", 66").
