Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Jul 11 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Weak, low-frequency radio activity was observed early on the 11th. Region 2766 (N05W72, Axx/alpha) re-emerged with spots during the period. No Earth-directed CMEs were observed during the reporting period.

Model runs of the 08 Jul, slow moving CME suggested a possible weak glancing blow on 14 Jul.

Forecast: Solar activity is expected to be very low on 11-13 Jul.

Energetic Particles

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

Forecast: Both the greater than 2 MeV electron and 10 MeV proton fluxes are expected to remain below event thresholds over 11-13 Jul.

Solar Wind

24 hr Summary: Solar wind parameters remained at nominal levels. Solar wind speed averaged 325 km/s. Total field was at or below 5 nT while the Bz component varied between +3/-4 nT. Phi angle was oriented in a positive solar sector.

Forecast: Solar wind parameters are expected to continue at nominal levels on 11 Jul. Weak influences from a positive polarity CH HSS are expected to enhance the geomagnetic field on 12-13 Jul.

Geospace

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

Forecast: The geomagnetic field is expected to be quiet on 11 Jul. Unsettled conditions are expected on 12-13 Jul due to CH HSS effects.
