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

Solar Activity

24 hr Summary: Solar activity remained at very low levels. The visible disk remained spotless. No Earth-directed CMEs were observed in available satellite imagery.

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

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels. The greater than 10 MeV proton flux remained at background values.

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

Solar Wind

24 hr Summary: Solar wind parameters became slightly enhanced due to a heliospheric current sheet crossing event this period. Between around 10/1300-11/0600 UTC solar wind density values increased to around 20 and the magnetic field strength briefly increased to a peak of around 7 nT. The Bz component briefly reached -7 nT during the enhancement, however, solar wind parameters quickly returned to near-background levels following the event.

Forecast: Solar wind parameters are expected to persist at nominal levels over 11-12 May. A slight increase is expected by 13 May due to the influence of a small, isolated, equatorial positive polarity CH HSS.

Geospace

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

Forecast: The geomagnetic field is expected to remain at quiet levels on 11-12 May. By 13 May, unsettled intervals are likely due to weak positive polarity CH HSS influence.
