Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Aug 03 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2670 (S05E52, Cso/beta) produced a few B-class flares during the period. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be at very low levels with a chance for C-class flares during the next three days (03-05 Aug).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to high 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 with a chance for high levels throughout the period (03-05 Aug). 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 indicated a return to ambient conditions. Solar wind speed steadily decreased throughout the period from 425 km/s to 375 km/s. Total field strength was between 1 and 7 nT. The Bz component was mostly northward and ranged between +5/-6 nT. The phi angle was negative.

Forecast: The solar wind environment is expected to remain at nominal levels on day one (03 Aug). The arrival of a recurrent positive polarity, polar connected coronal hole is anticipated late on day two (04 Aug) and the associated enhancement in solar wind conditions is expected to persist into day three (05 Aug).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Quiet levels are expected on day one (03 Aug) and early on day two (04 Aug). Conditions are likely to increase to G2 (Moderate) geomagnetic storm levels late on 04 Aug due to the arrival of a recurrent positive polarity, polar connected coronal hole high speed stream. Unsettled to G1 (Minor) conditions are likely on day three (05 Aug) as CH HSS effects continue.
