Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jul 29 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low and no events were observed this period. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to continue at very low levels on day one (29 Jul). An increasing chance for C-class flare activity on days two and three (30-31 Jul) and slight chance for M-Class (R1-R2/Minor-Moderate) events by day three (31 Jul) are likely due to the anticipated return of old Region 2665.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels this period with a peak flux of 14,317 pfu observed at 28/1510 UTC. The greater than 10 MeV proton flux was at background levels.

Forecast: The greater than 2 MeV electron flux is expected to reach high levels on days one and two (29-30 Jul) with only normal to moderate levels likely on day three (31 Jul) due to a predicted period of enhanced geomagnetic field activity.

Solar Wind

24 hr Summary: Solar wind parameters continued to trend towards nominal conditions due to the waning influence of a CH HSS.

Forecast: The near-Earth solar wind environment is expected to continue at background levels on days one and two (29-30 Jul) with a weak enhancement expected on day three (31 Jul) due to the influence of a negative polarity CH HSS.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled this period from the lingering influence of a waning CH HSS.

Forecast: The geomagnetic field is expected to be quiet on days one and two (29-30 Jul) under a nominal solar wind regime. Periods of active conditions are expected on day three (31 Jul) as a negative polarity CH HSS is expected to disturb Earths magnetosphere.
