Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Jun 02 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2764 (N34, Lo=165) decayed to plage and was inactive. Minor B-level x-ray enhancements were observed with an area rounding the southeast limb. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Very low solar activity is expected to continue on 02-04 Jun. Although Region 2764 is now inactive, the area emerging onto the disk from the southeast has continued flare potential based on recent activity.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to continue at primarily normal levels, with a few brief moderate periods 02-04 Jun. The greater than 10 MeV proton flux is expected to continue at background.

Solar Wind

24 hr Summary: Solar wind parameters suggested a mildly-disturbed IMF. Total field peaked at 8 nT, and remained marginally elevated through the reporting period. Bz was southward in excess of -5 nT for 6 to 8 hours starting around 01/18 UTC. Solar wind speed generally decreased from about 380 km/s to 325 km/s by 02/12 UTC. The phi angle was predominantly negative, but underwent positive sector shifts around 01/17 UTC.

Forecast: Solar wind conditions are anticipated to be nominal, but mild enhancements remain possible over the next three days (02-04 Jun).

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled due to a mildly-enhanced solar wind environment.

Forecast: Active conditions are expected on 02 June with sustained, elevated solar wind conditions. Mostly quiet conditions are anticipated on 03 and 04 Jun with isolated unsettled periods.
