Solar Activity

.24 hr Summary...
Solar activity continued at very low levels. Region 2776 (S14W38,
Hsx/alpha)remained quiescent. No Earth-directed CMEs were observed in
available satellite imagery.

.Forecast...
Solar activity is expected to be very low on 22-24 Oct.

Energetic Particle

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

.Forecast...
The greater than 2 MeV electron flux is expected to be at moderate to
high levels on 22-24 Oct. The greater than 10 MeV proton flux is
expected to persist at background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters were at nominal levels. Total field strength
averaged near 7 nT, the Bz component saw a maximum southward deflection
to -5 nT, wind speed was between 330-415 km/s, and the Phi angle was
oriented predominantly in the negative sector.

.Forecast...
Solar wind parameters are expected to see intermittent enhancements on
22-24 Oct due to the influence of several CH HSS.

Geospace

.24 hr Summary...
The geomagnetic field was quiet to unsettled.

.Forecast...
The geomagnetic field is expected to be at quiet to active levels, with
G1 (Minor) levels likely on 22-23 Oct, due to influences from a series
of extensions from the northern crown CH HSS. Unsettled to active levels
are expected on 24 Oct as CH HSS effects persist, yet begin to subside.
