Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Jun 04 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. The solar disk was spotless. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to remain at very low levels on 04-06 Jun.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels with a peak flux of 2,270 pfu observed at 03/1755 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 levels with a chance for high levels all three days (04-06 Jun). The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels over the period. Total field ranged from 1-7 nT while the Bz component was between +5/-4 nT. Solar wind speed ranged from 292-348 km/s. Phi angle switched from negative (towards) to a mostly positive (away) sector at approximately 03/1628 UTC.

Forecast: Solar wind parameters are expected to be at or near nominal levels on 04-06 Jun with possible weak CH HSS enhancements on 04-05 Jun.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Quiet to unsettled conditions are expected on 04-05 Jun due to possible weak CH HSS effects. Mostly quiet levels are expected on 06 Jun.
