Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Aug 05 1230 UTC.

Solar Activity

24 hr Summary: Solar activity continued at very low levels. Region 2770 (N23E53, Cso/beta) remained relatively inactive, producing only a few B-level enhancements in the X-ray flux. No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to remain at very low levels for 05-07 Aug.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux intermittently reached high levels, with a peak flux of 1420 pfu at 05/1145 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 05-06 Aug before returning to moderate levels by 07 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 reflected the continued, yet waning effects of a positive polarity CH HSS. Solar wind speeds began the period near 660 km/s before eventually decreasing to near 500 km/s by periods end. Total field strength averaged near 3 nT, and the Bz component averaged near +/-3 nT. Phi was predominantly in a positive orientation while undertaking several brief oscillations into a negative solar sector.

Forecast: Solar wind parameters, measured at the DSCOVR spacecraft, should continue their waning trend on 05 Aug as positive polarity CH HSS effects subside. A gradual return to an ambient-like, background environment is anticipated for 06-07 Aug.

Geospace

24 hr Summary: The geomagnetic field was at quiet levels as CH HSS influence diminished.

Forecast: Mostly quiet conditions are anticipated for the remainder of 05 Aug as CH HSS influence gradually subsides. Quiet conditions should then persist through 06-07 Aug.
