Here is the current forecast discussion on space weather and geophysical activity, issued 2016 Aug 03 1230 UTC.
Solar Activity
24 hr Summary: Solar activity was very low. There were no active sunspots on the visible disk and no coronal mass ejections observed in satellite imagery during the reporting period.
Forecast: Solar activity is expected to continue at very low levels over the next three days (03-05 Aug).
Energetic Particles
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 throughout the period.
Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels for the next three days (03-05 Aug). The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period (03-05 Aug).
Solar Wind
24 hr Summary: Solar wind parameters, as measured at the DSCOVR spacecraft, indicated continued influence from CH HSS activity. Solar wind speed started the period at approximately 400 km/s and increased to period ending values near 450 km/s. Total field strength reached a high of 25 nT while the Bz component of the IMF had several prolonged periods of southward orientation with a low value of -19 nT. The phi angle was predominantly positive.
Forecast: Solar wind parameters are expected to remain enhanced for the second half of day one (03 Aug) due to continued positive polarity coronal hole high-speed stream influence. This enhancement in the solar wind environment is expected to persist through days two and three (04-05 Aug).
Geospace
24 hr Summary: The geomagnetic field was at unsettled to G1 (Minor) storm levels due to CH HSS effects.
Forecast: The geomagnetic field is expected to be at G1 (Minor) storm levels on day one (03 Aug) due to continued influence from the positive polarity CH HSS mentioned above. Active levels are forecast on days two and three (04-05 Aug) as high speed stream effects continue to impact the Earths magnetosphere.
