Solar Activity

.24 hr Summary...
Solar activity was very low. The visible disk was spotless. No
Earth-directed CMEs were observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be at very low levels for the next three
days (24-26 Nov).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at moderate to high levels with
a peak flux of 4,658 pfu observed at 23/1555 UTC. 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 for the next three days (24-26 Nov) due to CH HSS
influences. The greater than 10 MeV proton flux is expected to continue
at background levels all three days.

Solar Wind

.24 hr Summary...
Solar wind parameters continued to decline towards nominal levels today.
Solar wind speed decreased from approximately 425 km/s to near 300 km/s
by the periods end. Total field ranged from 2 to 6 nT while the Bz
component was between +3/-4 nT. Phi angle was oriented in a mostly
positive solar sector.

.Forecast...
Solar wind parameters are expected to be at nominal levels over the next
three days (24-26 Nov).

Geospace

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

.Forecast...
The geomagnetic field is expected to be at quiet to unsettled levels on
day one (24 Nov). Mostly quiet levels are expected on days two and three
(25-26 Nov) under a nominal solar wind environment.
