Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Dec 13 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 13-15 Dec.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 13-15 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, as measured by the ACE spacecraft, reflected nominal conditions. Solar wind speeds averaged near 400 km/s. Total field was between 1-6 nT. Phi angle was variable.

Forecast: Solar wind parameters are expected to remain near nominal levels over 13-15 Dec.

Geospace

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

Forecast: The geomagnetic field is expected to be mostly quiet over 13-15 Dec.
