Solar Activity

.24 hr Summary...
Solar activity was at low levels. Region 4566 (S07W28,
Dkc/beta-gamma-delta) produced the majority of the C-class flares. The
largest was a C9.3/Sf flare at 10/0834 UTC. The region also produced a
C8.6 flare at 1002 UTC and exhibited separation and decay in its
trailing spots while maintaining a delta within its leader spots.
Slight growth was observed in Region 4568 (S08W08, Bxo/beta). New spots
emerged to the SW of Region 4572 (N12E64, Hsx/alpha), but has yet to be
numbered. The rest of the spotted regions were relatively stable or in
decay.

No Earth-directed CMEs were observed in available coronagraph imagery.

.Forecast...
M-class flares (R1-R2/Minor-Moderate) are likely, with a slight chance
for an X-class flare (R3-Strong), over 10-12 Nov.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 4,674 pfu observed at 09/1630 UTC. The greater than 10 MeV
proton flux was at background levels.

.Forecast...
The greater than 2 MeV electron flux is likely to reach high levels over
10-12 Nov. There is a slight chance for the greater than 10 MeV proton
flux to exceed S1 (Minor) levels over 10-12 Nov.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected the influence from a negative polarity
CH HSS. Total field ranged from 2-5 nT while the Bz component was
between +/-4 nT. Solar wind speed decreased from approximately 750 km/s
to near 635 km/s. Phi angle was mostly negative.

.Forecast...
The solar wind environment is expected to remain enhanced as CH HSS
influences continue over 10 Nov and gradually diminish on 11-12 Nov.

Geospace

.24 hr Summary...
The geomagnetic field was mostly unsettled under persistent CH HSS
influence.

.Forecast...
Quiet to active conditions are expected on 10 Nov as HSS activity
persists. Quiet to unsettled conditions are expected on 11-12 Nov as HSS
activity gradually diminishes.
