Here is the current forecast discussion on space weather and geophysical activity, issued 2020 May 03 1230 UTC.

Solar Activity

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

Forecast: Solar activity is expected to remain at very low levels on 03-05 May.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 03-05 May. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, reflected mostly nominal conditions. Total magnetic field strength was between 2-7 nT and no significant periods of southward Bz were observed. Solar wind speeds varied between ~290-350 km/s. Phi angle was predominantly oriented in the negative sector.

Forecast: The solar wind environment is likely to become enhanced on 03-04 May in response to transient influence from the 27 Apr CME. An additional enhancement is likely on 05 May due to the anticipated arrival of an isolated, negative polarity CH HSS.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Quiet to unsettled geomagnetic conditions are expected on 03-05 May due to possible transient influence from the aforementioned 27 Apr CME and CH HSS influence.
