Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Jan 31 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2757 (N04W63, Hrx/alpha) was stable and remained inactive. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to continue at very low levels on 31 Jan - 02 Feb.

Energetic Particle

24 hr Summary: Both the greater than 2 MeV electrons and 10 MeV protons remained below event thresholds this period.

Forecast: Both the greater than 2 MeV electrons and 10 MeV protons are expected to remain below event thresholds on 31 Jan - 02 Feb.

Solar Wind

24 hr Summary: Solar wind parameters were enhanced due to likely influence of the negative polarity southern crown and possible proximity of the HCS. Wind speeds averaged between 400-450 km/s for the majority of the period. However, speeds increased further just after 31/0200 UTC, varying between 450-500 km/s and briefly reaching 550 km/s. Total field values also saw weak enhancements of up to 8 nT, but have since settled to under 5 nT. The Bz component underwent several, extended southward deflections with -7 nT being the greatest. The phi angle was predominantly in a negative solar sector.

Forecast: The enhancement in the solar wind environment is anticipated to continue through 31 Jan, and begin to decline over the course of 01 Feb. A return to ambient, background-like conditions is expected 02 Feb.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled, with isolated active periods.

Forecast: The influence of a negative polarity CH HSS and possible HCS proximity is expected to cause isolated periods of unsettled, with a chance for active levels, on 31 Jan. Quiet to unsettled conditions are likely 01 Feb, and mostly quiet conditions are anticipated 02 Feb.
