Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Mar 31 1230 UTC.

Solar Activity

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

Forecast: Solar activity is expected to continue at very low levels on 31 Mar-02 Apr.

Energetic Particle

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

Forecast: 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

24 hr Summary: 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.

Forecast: 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.

Geospace

24 hr Summary: The geomagnetic field ranged from quiet to active levels due to CH HSS effects.

Forecast: 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 persist.
