Solar activity was very low. No Earth-directed CMEs were observed in
available coronagraph imagery.
Solar activity is expected to continue at very low levels on 31 Mar-02
The greater than 2 MeV electron flux was normal to moderate and the
greater than 10 MeV proton flux maintained background values.
The greater than 2 MeV electron flux is expected to reach high levels on
31 Mar-02 Apr due to CH HSS influences. The greater than 10 MeV proton
flux is expected to continue at background levels.
Solar wind parameters indicated the onset of a negative polarity CH HSS.
Solar wind speed increased from approximately 405 km/s to a maximum of
527 km/s at 30/2155 UTC. Total field ranged from 2-8 nT while the Bz
component was between +6/-7 nT. Phi angle was predominantly oriented in
a negative solar sector.
Influences from the negative polarity CH HSS are anticipated to continue
causing a mildly disturbed IMF and enhanced solar wind speed field on 31
Mar-02 Apr. Conditions are anticipated to weaken slightly on 01-02 Apr
as total IMF strength decreases.
The geomagnetic field ranged from quiet to active levels due to CH HSS
Quiet to active periods are expected to continue through 31 Mar
followed by quiet to unsettled periods on 01-02 Apr as CH HSS effects
