Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Mar 22 1230 UTC.

Solar Activity

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

Forecast: Very low solar activity is expected to continue 22-24 Mar.

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 be at normal to moderate levels on 22-24 Mar. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters indicated continued interaction with a southern crown CH HSS. Solar wind speed ranged from 404-505 km/s. Total field ranged from 1-6 nT while the Bz component was between +3/-4 nT. Phi angle was mostly oriented in a negative solar sector.

Forecast: Occasional enhancements in the solar wind environment are expected through 23 Mar due to continued interaction with the southern crown CH HSS. A return to ambient conditions is anticipated on 24 Mar.

Geospace

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

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels with a chance of isolated active periods through 23 Mar due to continued interaction with a negative polarity, southern crown CH HSS. Mostly quiet conditions are expected on 24 Mar.
