Solar activity decreased to moderate levels. Region 9714 (S09W95) produced a long-duration M1 X-ray flare at 02/1500 UTC as it crossed the west limb. A post-flare loop prominence system followed this flare. Region 9715 (N04W37) produced isolated C-class subflares. It remained the most impressive region on the disk, but showed signs of gradual decay with a modest decrease in area. However, it remained magnetically complex as a magnetic delta configuration persisted within its interior spots. Region 9718 (S06E16) showed minor growth and produced isolated subflares, one of which reached C-class. Some polarity mixing persisted in the trailer portion of this region. New Region 9725 (S11W45) emerged during the period. New Region 9726 (S15E69) rotated into view today.

Solar activity is expected to be mostly moderate during the period with isolated M-class flares likely. There will also be a chance for an isolated major flare during the period from Region 9715.

Geomagnetic field activity was at mostly quiet levels.

Quiet to unsettled levels are expected. However, there will be a chance for active periods during 04 - 05 December due to coronal hole effects. There will be a slight chance for a proton flare from Region 9715.
