Solar activity remained at moderate levels. Region 9775 (S06W86) produced an M1/Sf flare at 16/1013 UTC as well as occasional C-class subflares. No significant changes were observed in this region as it began to cross the west limb. Region 9773 (N16W93) produced an isolated C-class subflare as it crossed the west limb early in the period. Region 9782 (N06E05) showed a minor increase in area, but appeared to simplify due to the loss of a delta magnetic configuration in the southern portion of its leader spots. New Region 9786 (S26E07) was numbered.

Solar activity is expected to be at low to moderate levels. An isolated M-class flare will be possible from Region 9775 as it continues to rotate out of view. There will also be a chance for an M-class flare from Region 9782.

Geomagnetic field activity was at mostly quiet levels. The greater than 10 MeV proton event that began at 15/1435 UTC ended at 16/1205 UTC. The maximum for this event was 15 PFU at 15/2000 UTC. The greater than 2 MeV electron flux briefly reached high levels during the latter half of the period.

Geomagnetic field activity is expected to be at quiet to unsettled levels. There will be a slight chance for a proton flare during the period. The greater than 2 MeV electron flux is expected to decrease to normal to moderate levels.
