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

Solar Activity

24 hr Summary: Solar activity was very low and no Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Very low solar activity is expected 11-13 Mar.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to be normal to moderate 11-13 Mar. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were still indicative of a slow regime. Total IMF strength ranged from 1 to 4 nT and the Bz component underwent only weak deviations. Solar wind speeds decreased from ~325km/s to ~295 km/s by periods end. Densities varied over the period from ~5 to 13.92 particles per cubic cm, likely due to proximity of the HCS. Phi was predominantly negative, but under went relatively brief excursions into a positive solar sector.

Forecast: A slow solar wind regime is anticipated to continue 11-13 Mar. There is a chance for minor disturbances or enhancements, in particular on 11 Mar, due to tenuous CH HSS connections or minor influences from proximity to the north flank of the south polar CH HSS.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be primarily quiet, with a chance for isolated unsettled periods, on 11 Mar due to weak CH HSS influences. Predominantly quiet conditions are expected to prevail 12-13 Mar.
