Solar Activity

.24 hr Summary...
Solar activity continued at very low levels. Region 4564 (N04E36,
Dri/beta) developed a few additional rudimentary spots this period while
Region 4565 (N13E55, Hsx/alpha) remained unchanged.

No Earth-directed CMEs were observed at the available coronagraph
imagery.

.Forecast...
Solar activity is expected to be at very low levels with a chance for
isolated C-class flares through 03 Nov.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels.
The greater than 10 MeV proton flux remained steady at background
levels.

.Forecast...
The greater than 2 MeV electron flux is expected to continue at normal
to moderate levels through 02 Nov, with high levels likely on 03 Nov.
The greater than 10 MeV proton flux is expected to continue at
background levels through 03 Nov.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected the onset of CIR ahead of a positive
polarity CH HSS. Total magnetic field strength reached a peak of 13 nT.
The Bz component was sustained southward at times this period, and
reached as far south as -11 nT. Solar wind speeds increased from a low
of around 430 km/s to a peak near 615 km/s by around 31/2200 UTC, before
beginning a gradual decline in the hours after. Phi angle was
predominantly oriented in the positive solar sector.

.Forecast...
Enhanced solar wind conditions are likely to continue through 02 Nov due
to positive polarity CH HSS influences. A return to mostly nominal
conditions is expected over 03 Nov.

Geospace

.24 hr Summary...
The geomagnetic field reached G1-G2 (Minor-Moderate) storm levels due to
positive polarity CH HSS influences.

.Forecast...
The geomagnetic field is likely to reach G1 (Minor) geomagnetic storm
levels on 01 Nov due to continued influence from a positive polarity CH
HSS. Quiet to unsettled levels are likely on 02 Nov, with mostly quiet
conditions likely on 03 Nov, as CH HSS influence wanes.
