Solar activity reached moderate levels this past week, but has now
returned to, and remains at, lower levels. Region 4248 produced an
M1.1 flare on October 20, which was the largest event of the period.
Region 4261 was numbered this period as it rotated into better
viewing conditions.

Region 4262 was numbered this period as well, splitting it from
Region 4257. Additionally, new spots were noted near ...

size while gaining multiple new spots. Subsequently, AR4246 was the
main provider of activity which included an M1.2 flare on October
13. Several coronal mass ejections (CMEs) with potential
Earth-directed components are in the mix at this time.

Additional modeling efforts are underway to perhaps confirm those
suspicions. The largest f...
