Solar activity was high, due to the occurrence of several M-class events. The largest was an east limb long duration M4.8 enhancement, peaking at 01/1555 UTC. The presumed source is old Region 9690 (S17, L=025), which is expected to re-emerge on the east limb on 02 December. Other activity included numerous flares from Region 9714 (S10W84), some of which were accompanied by weak M-class enhancements, and an impulsive M2/2n flare from Region 9718 (S07E30). Three new regions were numbered today: 9722 (S16W19), 9723 (S09E45), and 9724 (N09E74). The latter produced an M1/Sf event at 01/1744 UTC. None of today's activity appeared to produce any earth-directed CME's, and no CME-related radio sweeps were observed.

Solar activity is expected to be moderate to high for the next three days. Regions 9714, 9715 (N05W23), 9718, and emergent regions on the east limb all appear capable of isolated major flares.

The geomagnetic field was quiet to unsettled throughout the period.

The geomagnetic field may become active, with isolated minor storm conditions possible, within the next 24 hours, as shock passages from CME activity of 28-29 November are anticipated. Activity is expected to be predominantly unsettled thereafter, with some influence of a recurrent coronal hole possible late in the forecast period.
