Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Aug 02 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2670 (S05E67, Cso/beta) was numbered and managed several B-class flares. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is likely to be at low levels, with a slight chance for M-class (R1-R2, Minor-Moderate) flares, for the next three days (02-04 Aug) due to the flare potential of Region 2670.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels. 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 on days one and two (02-03 Aug), then increase back to high levels by day three (04 Aug) due to elevated solar wind speeds. 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 characteristic of a negative polarity CH HSS. Solar winds fluctuated between 375 and 450 km/s. Total field strength gradually decreased from 10 nT early to 5 nT by periods end. The Bz component was mostly northward and ranged between +8/-2 nT. The phi angle was primarily negative.

Forecast: The solar wind environment is expected to remain enhanced on day one (02 Jul) due to the continued influence of a negative polarity CH HSS. A return to nominal levels is expected by days two and three (03-04 Aug) as the CH HSS becomes less influential on the near-Earth environment.

Geospace

24 hr Summary: The geomagnetic field was mostly quiet with an isolated unsettled period.

Forecast: Quiet to unsettled levels are expected on day one (02 Aug), with a chance for active conditions early, as CH HSS influences persist. Days two and three (03-04 Aug) are expected to be mostly quiet as these CH HSS effects taper.
