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

Solar Activity

24 hr Summary: Solar activity was very low. No active regions with sunspots were observed and no Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to be very low over 20-22 Jun.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux and the greater than 10 MeV proton flux remained below event thresholds this period.

Forecast: Both the greater than 2 MeV electron and greater than 10 MeV proton fluxes are expected to persist below event thresholds for 20-22 Jun.

Solar Wind

24 hr Summary: Solar wind parameters were indicative of a mostly nominal solar wind regime. Solar wind speed gradually increased through the period from around 300 km/s to a peak of near 360 km/s at about 20/0430 UTC. An average speed of about 330-340 km/s persisted through periods end. Total field strength values peaked at 7 nT while the Bz component reached a maximum southward deflection of -7 nT at about 20/0340 UTC. The phi angle was in a steady positive sector through about 20/0100 UTC and became variable for 3 hours before settling into a negative orientation.

Forecast: Solar wind parameters are expected to persist at mostly background levels over 20-22 Jun under a nominal solar wind regime.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be predominately quiet on 20-22 Jun.
