Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Jan 17 1230 UTC.

Solar Activity

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

Forecast: Very low solar activity is expected to continue 17-19 Jan.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels 17-19 Jan. The greater than 10 MeV proton flux is expected to remain at background.

Solar Wind

24 hr Summary: Solar wind parameters were at near-background levels. Solar wind speeds decreased from near 390 km/s to ~ 325 km/s. Total field strength peaked at 7 nT, and while there were numerous periods of Bz deflecting southward, none of the periods exceeded -5 nT. Phi was predominantly positive.

Forecast: A slow solar wind regime is anticipated to continue 17-19 Jan.

Geospace

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

Forecast: The geomagnetic field is expected to remain at mostly quiet levels on 17-19 Jan.
