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

Solar Activity

24 hr Summary: Solar activity was very low. The Region in the NE that was responsible for the M1 flare on 29 May rotated onto the visible disk as plage with small intermittent pores. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to be very low with a slight chance for C-class flares over 31 May - 02 Jun.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels 31 May - 02 Jun and the greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters gradually decreased to nominal levels over the period. Solar wind speed ranged from 352-431 km/s. Total field decreased from 12 nT to near 3 nT while the Bz component was between +11/-8 nT. Phi angle was oriented in a negative (towards) solar sector.

Forecast: Solar wind parameters are expected to be at or near nominal levels through 02 Jun.

Geospace

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

Forecast: Mostly quiet levels are expected for 31 May - 02 Jun under a nominal solar wind regime.
