Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Jun 04 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2765 (Hsx/alpha) was unremarkable. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Very low solar activity is expected, with only a slight chance for C-class flares 04-06 Jun due to apparent weakening activity trend of Region 2765.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was predominantly normal, and the greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is expected to remain at primarily normal levels and the greater than 10 MeV proton flux is expected to continue at background levels 04-06 Jun.

Solar Wind

24 hr Summary: Solar wind parameters indicated a slow regime. Total IMF strength varied between 1 and 4 nT, and the Bz component underwent only weak deviations. Solar wind speed was generally around 325 km/s. The phi angle was predominantly negative.

Forecast: The solar wind field is anticipated to continue as primarily a slow regime 04-05 Jun; however, current sheet proximity may cause occasional minor disturbances in the IMF. Additionally, a tenuous CH currently near central meridian may cause weak enhancements beginning 06 Jun.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be quiet, with a chance for isolated unsettled periods 04-05 June due to SSBC effects. Minor CH HSS influences by 06 June will likely result in quiet to unsettled conditions.
