Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Jun 03 1230 UTC.

Solar Activity

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

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

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached high levels with a peak flux of 3,770 pfu observed at 02/1950 UTC. The greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels all three days (03-05 Jun). The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters remained at nominal levels. Total field ranged between 1-5 nT, the Bz component varied between +2 nT to -3 nT, solar winds remained below 350 km/s and the phi angle remained in a predominantly negative orientation.

Forecast: Solar wind parameters are expected to be slightly enhanced for the next three days (03-05 Jun) due to a pair of small, isolated CH HSSs.

Geospace

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

Forecast: Geomagnetic field conditions are expected to range from quiet to unsettled levels through the forecast period (03-05 Jun) due to weak CH HSS influence.
