Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Jun 06 1230 UTC.

Solar Activity

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

Forecast: Solar activity is expected to remain at very low levels on 06-08 Jun.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels with a peak flux of 179 pfu at 05/2010 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 normal to moderate levels all three days (06-08 Jun). The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters continued at nominal levels with solar wind speed ranging from 305-350 km/s. Total field ranged from 1-5 nT while the Bz component was between +/-3 nT. Phi angle was oriented in a negative solar sector.

Forecast: Solar wind parameters are expected to be at nominal levels on 06 Jun. Early on 07 Jun, a slight enhancement in the solar wind environment is possible due to a weak connection to a negative polarity, polar extension coronal hole. An additional enhancement is possible late on 08 Jun as an additional negative polarity CH HSS moves into geoeffective position.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet for 06 Jun. Quiet to unsettled conditions are expected on 07-08 Jun, with a chance for isolated active periods, due to CH HSS influence.
