Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Aug 02 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained very low. Region 2717 (S07E23) decayed into a plage area. No CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to remain very low all three days (2-4 Aug).

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels all three days (2-4 Aug). The greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels. Solar wind speeds were between 350 to 450 km/s. Total field and Bz were at benign values. Phi switched to a negative orientation near 02/0300Z.

Forecast: A nominal solar wind environment is expected to continue on days one and two (02-03 Aug). Day three (04 Aug) is expected to see an enhancement due to the arrival of a negative polarity CIR/CH HSS.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be quiet to unsettled on days one and two (02-03 Aug). There is a chance to see an isolated active period on day three (04 Aug) due to the aforementioned CH HSS.
