Solar Activity
.24 hr Summary...
Solar activity was low. Region 2786 (S17E10, Fki/beta-gamma) produced multiple C-class flares including a C3/Sf observed at 28/2318 UTC. The region also produced an LDE C1 x-ray event observed at 29/0116 UTC. Slight growth was observed in the intermediate area of the region. New Region 2788 (S26W00, Cro/beta) was numbered this period. This new region had formally been the trailer portion of Region 2785 (S23W15, Hsx/alpha). The evolving magnetic structure of the sunspot complex comprised of Regions 2785 and 2788 supports these as separate sunspot groups. The remainder of the spotted regions were stable and quiet. No Earth-directed CMEs were observed.
Solar activity is likely to be at low levels with a slight chance for M-class flare (R1-R2, Minor-Moderate) activity on 29 Nov-01 Dec.

Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels today with a peak flux of 1,673 pfu observed at 28/1850 UTC. The greater than 10 MeV proton flux was at background levels.
The greater than 2 MeV electron flux is expected to be at normal to high levels on 29 Nov and normal to moderate levels on 30 Nov-01 Dec. The greater than 10 MeV proton flux is expected to persist at background levels all three days.

Solar Wind
.24 hr Summary...
Solar wind parameters were at nominal levels. Solar wind speeds gradually declined through the period from about 425 km/s to near 350 km/s. Total field ranged from 3-8 nT, the Bz component varied between +5 to -6 nT and the phi angle was mostly in a positive (away) solar sector.
Nominal solar wind conditions are expected on 29 Nov-01 Dec.

.24 hr Summary...
The geomagnetic field was at quiet to isolated unsettled levels.
The geomagnetic field is expected to be mostly quiet on 29 Nov-01 Dec.
