Here is the current forecast discussion on space weather and geophysical activity, issued 2016 Jun 08 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2552 (N174W36, Cro/beta) developed rudimentary penumbra over the past 24 hours. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to continue at very low levels with a slight chance for C-class flares all three days (08-10 Jun).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels with a peak flux of 1,500 pfu at 07/1635 UTC. The greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels all three days (08-10 Jun) and the greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the ACE spacecraft, returned to near-background conditions. Total magnetic field strength was mostly averaged around 5 nT. Solar wind speeds were slightly enhanced between 450 - 500 km/s. Phi angle was variable throughout the past 24 hours.

Forecast: Solar wind conditions are expected to remain at similar ambient levels over days one and two (08-09 Jun). Day three (10 Jun) may see a slight enhancement later in the day due to an anticipated SSBC.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled.

Forecast: The geomagnetic field is expected to be primarily quiet over days one and two (08-09 Jun). Day three (10 Jun) may see increased periods of unsettled associated with an anticipated SSBC.
