Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Dec 11 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. The visible disk was spotless. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be at very low levels on 11-13 Dec.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected to persist at normal to moderate levels on 11-13 Dec. The greater than 10 MeV proton flux is expected to persist at background levels throughout the period.

Solar Wind

24 hr Summary: Solar wind parameters were nominal despite influence from a weak CH HSS. Solar wind speed reached 450 km/s, but have since decreased to ~400 km/s. Total field stayed below 10 nT and the Bz component reached a maximum deflection of -7 nT. Phi was predominantly negative.

Forecast: Solar wind parameters are expected to remain nominal through 13 Dec.

Geospace

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

Forecast: Mostly quiet conditions are expected 11-13 Dec.
