Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Jun 09 1230 UTC.

Solar Activity

24 hr Summary: A spotless solar disk kept solar activity at very low levels. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be at very low levels over the next three days (09-11 Jun).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached high levels this period with a peak flux of 2090 pfu observed at 08/2010 UTC. The greater than 10 MeV proton flux was steady at background levels throughout the period.

Forecast: The greater than 2 MeV electron flux is expected to reach high levels the next two days (09-10 Jun), then decrease to moderate levels on day three (11 Jun). The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, reflected nominal conditions. Solar wind speeds were between 330-390 km/s. Total field was below 5 nT. Phi was mostly positive.

Forecast: The solar wind environment is expected to be at or near background levels all three days (09-11 Jun).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Days one through three (09-11 Jun) are expected to be quiet under a background solar wind regime.
