Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Jan 22 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. Region 2797 (S18E14, Hax/alpha) was stable and inactive. Region 2798 (S16E28, Axx/alpha) decayed and was also void of significant activity. A new spot group emerged in the NW portion on the disk. We await further observations from the SOON analysts before assigning a region number. No Earth-directed CMEs were observed during the period.

Forecast: Solar activity is expected to remain at very low levels, with a slight chance for C-class activity, on 22-24 Jan.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels while the greater than 10 MeV proton flux is expected to persist at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels. Total magnetic field strength was at or below 5 nT while the Bz component varied between +/-2 nT. Wind speed averaged around 300 km/s. Phi was variable.

Forecast: A nominal solar wind environment is expected for the next three days (22-24 Jan).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Mostly quiet conditions are anticipated through for 22-24 Jan.
