Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Aug 09 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. Region 2770 (N23E01, Hsx/alpha) was quiet and stable over the period. No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to remain at very low levels, with a slight chance for C-class flares, on 09-11 Aug.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels, with a peak flux of 2,170 pfu observed at 08/1840 UTC. The greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is anticipated to reach high levels on 09-11 Aug. The greater than 10 MeV proton flux is expected to remain at background levels for the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, reflected nominal conditions. Total magnetic field strength was at or below 4 nT while the Bz component varied weakly between +/-3 nT. Solar wind speeds declined from ~450 km/s to ~340 km/s by the end of the period. Phi angle was predominantly oriented in the positive sector.

Forecast: Solar wind parameters are likely to continue at nominal levels over 09-11 Aug.

Geospace

24 hr Summary: The geomagnetic field was at quiet levels.

Forecast: The geomagnetic field is expected to be mostly quiet on 09-11 Aug under a nominal solar wind regime.
