Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Jul 31 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Regions 2767 (S21W53, Hsx/alpha) and 2768 (N26E34, Axx/alpha) continued to exhibit signs of weak decay. No Earth-directed CMEs were observed in available imagery.

Forecast: Solar activity is expected to remain at very low levels for 31 Jul - 02 Aug.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron and 10 MeV proton fluxes are expected to remain below event threshold for 31 Jul - 02 Aug.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, continued to reflect nominal conditions. Total field strength averaged near 3 nT, the Bz component was between +2/-5 nT, and the solar wind speeds were between 315 and 370 km/s. Phi angle rotated between both phi angle orientations.

Forecast: The solar wind environment is expected to continue at nominal levels for 31 Jul. Enhancements consistent with a recurrent, positive polarity CH HSS are expected on 01-02 Aug.

Geospace

24 hr Summary: The geomagnetic field was quiet. Forecast: The geomagnetic field is expected to be quiet for 31 Jul and quiet to unsettled, with isolated active periods possible, on 01-02 Aug due to possible CH HSS influence.
