Solar Activity

.24 hr Summary...
Solar activity was very low. Region 2806 (S31W70, Cro/beta) remained
stable and quiet. No Earth-directed CMEs were observed in available
coronagraph imagery.

Solar activity is expected to remain at very low levels over 08-10 Mar.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels due to CH HSS influence. The greater than 10 MeV proton flux
remained at background levels.

The greater than 2 MeV electron flux is expected to be at moderate to
high levels through 08-09 Mar. A return to peak levels of moderate
levels is expected for 10 Mar. The greater than 10 MeV proton flux is
expected to remain at background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters, as measured by the DSCOVR spacecraft, reflected
waning influence of a positive polarity CH HSS. Total magnetic field
strength was between 5-7 nT while Bz was mostly positive with a brief
deflection to -6 nT at 07/1649 UTC. Solar wind speeds were in gradual
decline, starting the period between 500-550 km/s and ending the
reporting between 450-500 km/s. Phi angle was predominantly oriented in
the positive solar sector.

The solar wind speed is expected gradually trend towards nominal levels
over 08-09 Mar.


.24 hr Summary...
The geomagnetic field was quiet to active under waning CH HSS influence.

The geomagnetic field is expected to be quiet to unsettled on 08-09 Mar
in response to diminishing CH HSS effects. Quiet conditions are expected
on 10 Mar as nominal solar wind condition prevail.
