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

Solar Activity

24 hr Summary: Solar activity was at very low levels under a spotless visible disk. A CME was observed in SOHO/LASOC C2 coronagraph imagery on 19 Jul after 19/1135 UTC. The signature was slow-moving and in the NE quadrant. Modeling and analysis of the CME is ongoing.

Forecast: Solar activity is expected to be at very low levels on 20-22 Jul.

Energetic Particles

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

Forecast: The greater than 2 MeV electron and 10 MeV proton fluxes are expected to remain below event thresholds on 20-22 Jul.

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 5 nT. Solar wind speeds were between 318-366 km/s. Phi angle was predominantly oriented in the positive sector.

Forecast: Nominal solar wind parameters are anticipated on 20-22 Jul.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be at mostly quiet levels on 20-22 Jul.
