Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 05 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at low levels. Region 2661 (N06E20, Eao/beta-delta) produced a C2/Sf flare at 05/0514 UTC, the strongest of the period. Only minor changes were observed in the region over the past 24 hours. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: There is a diminishing chance for C-class flares over the next three days (05-07 Jun) with a slight chance for isolated M-class (R1-R2, Minor-Moderate) flare activity on day one (05 Jun).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux was at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels over the next three days (05-07 Jun) and 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 were indicate of a return to a nominal solar wind environment. Total magnetic field strength was between 2-5 nT and there were no significant periods of Bz south. Solar wind speeds were in steady decline, decreasing from 450 km/s to around 350-375 km/s by the periods end. Phi angle was oriented in the positive sector.

Forecast: Solar wind parameters are expected to persist at near-background levels under a nominal solar wind regime throughout the forecast period (05-07 Jun).

Geospace

24 hr Summary: The geomagnetic field was quiet under a background solar wind environment.

Forecast: Generally quiet geomagnetic field conditions are expected to prevail throughout the forecast period (05-07 Jun).
