Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Aug 02 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2768 (N26E07) decayed to plage. New Region 2769 (N26E60, Axx/alpha) was numbered. No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to remain at very low levels for 02-04 Aug.

Energetic Particle

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 on 02-04 Aug.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels until 02/0427 UTC when an enhancement of the solar wind speed and total field was observed, likely due to the onset of a positive polarity CH HSS. Total field increased to 12 nT by 02/1142 UTC and the Bz component reached a max southward deflection of -10 nT. Solar wind speed increased from approximately 318 km/s to near 385 km/s. Phi angle was predominantly oriented in a positive (away) solar sector.

Forecast: Solar wind parameters are expected to continue to be enhanced on 02-04 Aug as positive polarity CH HSS effects persist.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled.

Forecast: The geomagnetic field is expected to reach unsettled to active conditions on 02 Aug with quiet to unsettled levels continuing through 04 Aug as CH HSS effects persist.
