Solar activity was low during the past 24 hours due to numerous C-class flares. Regions 9687 (S19E49) and 9682 (N12W50) combined to produce a C5 event at 0741 UTC. An additional C5/Sf was produced by 9682 at 0935 UTC. Region 9682 was quieter today than yesterday and appears to have decreased slightly in area. Region 9687 also was quieter today. Preliminary analysis of 9687 indicates at least a beta-gamma magnetic class, and there may possibly be a weak delta sunspot in the group. Region 9684 (N05W15) showed some spot rotation and some development of the leader spot. A partial halo CME, reported by LASCO, entered the C2 field of view at 01/2230 UTC and was apparently associated with yesterday's M1 event out of Region 9682.

Solar activity is expected to be low to moderate during the next three days. There is a slight chance for a major flare or a proton producing flare. Regions 9682, 9684, and 9687 continue to be the major groups to watch for energetic flare activity.

The geomagnetic field was quiet during the past 24 hours.

The geomagnetic field is expected to be quiet to unsettled during the next 24-36 hours. An increase to unsettled to slightly active levels is forecast for the second and third days in response to the partial halo CME event that occurred late on 1 November.
