Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Apr 30 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Regions 2760 (S08W24, Cro/beta) and 2762 (N22W55, Axx/alpha) remained inactive. The CMEs originating from the western limb mentioned in the previous discussion were analyzed, modeled and determined to be misses.

Forecast: Solar activity is expected to remain very low 30 Apr - 02 May, with a slight chance for C-class flares.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 30 Apr - 02 May. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters reflected nominal conditions. Total magnetic field strength ranged from 1-5 nT, and the Bz component was benign. Solar wind speeds fell below 300 km/s. Phi began the period in a positive solar sector before becoming negative at approximately 29/1541 UTC.

Forecast: The solar wind environment is expected to remain at or near background levels throughout the forecast period (30 Apr - 02 May).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Mostly quiet geomagnetic conditions are expected on 30 Apr - 02 May as ambient solar wind conditions persist. Isolated periods of unsettled levels are possible throughout the forecast period.
