Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Jan 28 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Slight decay was observed in both Regions 2797 (S18W62, Axx/alpha) and 2800 (N18W28, Bxo/beta). No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to be very low on 28-30 Jan.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels with a peak flux of 3,240 pfu observed at 27/1930 UTC. The greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be moderate to high on 28-30 Jan while the greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters indicated the waning effects of a negative polarity CH HSS. Solar wind speed decreased from approximately 560 km/s to near 450 km/s. Total field ranged from 1-6 nT while the Bz component was between +3/-5 nT. Phi angle was predominantly negative.

Forecast: Solar wind parameters are expected to continue to diminish through 28 Jan. A return to nominal solar wind conditions is expected on 29-30 Jan.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled due to persistent CH HSS effects.

Forecast: The geomagnetic field is expected to be mostly quiet through 30 Jan.
