Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Jan 19 1230 UTC.

Solar Activity

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

Forecast: Solar activity is expected to remain very low on 19-21 Jan.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal levels 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 on 19-21 Jan. The greater than 10 MeV proton flux is expected to be at background levels all three days.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels over the period. Solar wind speed declined from approximately 480 km/s to near 390 km/s. Total field ranged from 3-4 nT while the Bz component was between +/-3 nT. Phi angle was oriented in a negative sector.

Forecast: The solar wind environment is expected to be at nominal levels on 19-21 Jan.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be at mostly quiet levels on 19-21 Jan under a nominal solar wind regime.
