Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Jun 07 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 07-09 Jun.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels. 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 (07-09 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 with solar wind speed ranging from 280-325 km/s. Total field ranged from 1-6 nT while the Bz component was mostly negative between +1/-3 nT. Phi angle was oriented in a mostly negative solar sector.

Forecast: Late 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 and into 09 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 at quiet to unsettled conditions on 07-09 Jun, with a chance for isolated active periods, due to CH HSS influence.
