Solar Activity

24 hr Summary: Solar activity was 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 20-22 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 be at normal to moderate levels on 20-22 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 with solar wind speed between 340-405 km/s. Total field ranged from 2-4 nT while the Bz component was between +/-3 nT. Phi angle was oriented in a mostly negative solar sector.

Forecast: The solar wind environment is expected to continue at nominal levels on 20-22 Jan.

Geospace

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

Forecast: The geomagnetic field is expected to be at mostly quiet levels on 20-22 Jan under a nominal solar wind regime.
