Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Feb 23 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. The visible disk was spotless. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to remain very low on 23-25 Feb.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached high levels, with a peak flux of 2,370 pfu. The greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels on 23-25 Feb due to elevated solar wind speeds. The greater than 10 MeV proton flux is expected to continue at background values.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the ACE spacecraft, reflected declining influence of a negative polarity CH HSS. Solar wind speeds ranged between 410 and 500 km/s. Total magnetic field strength was below 5 nT. Phi angle was oriented in the negative sector.

Forecast: The solar wind environment is expected to continue to trend towards background levels over 23-25 Feb.

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels in response to CH HSS influence.

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on 23-25 Feb due to waning CH HSS effects.
