Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Aug 20 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2772 (N18W55, Bxo/beta) remained stable over the period, only producing B-level enhancements in the X-ray flux. No Earth-directed CMEs were observed in available coronagraph imagery.

A CME-like signature became present on STEREO A early on 20 Aug. Therefore, the 16 Aug CME is likely a miss and confidence in a late arrival is low.

Forecast: Very low solar activity is expected to continue 20-22 Aug.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was normal to moderate levels and the greater than 10 MeV proton flux maintained background values.

Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels 20-22 Aug and the greater than 10 MeV proton flux is expected to remain at background.

Solar Wind

24 hr Summary: Solar wind parameters were indicative of a slow regime. Total field was below 5 nT, the Bz component was at or near neutral, and wind speeds decreased from ~335 km/s to ~ 310 km/s by the periods end. Phi was predominantly in a positive orientation.

Forecast: Solar wind conditions are anticipated to remain at ambient-like levels 20-21 Aug. Weak enhancements due to a weak CH HSS are anticipated for 22 Aug.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be at quiet levels 20-21 Aug. Quiet to unsettled levels are expected 22 Aug due to a weak CH HSS.
