Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Feb 25 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 satellite imagery.

Forecast: Solar activity is expected to remain very low on 25-27 Feb.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels. 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 25-27 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 reflected a return to background conditions. Solar wind speeds continued their downward trend, with end of period values near 350 km/s. Total field averaged near 4 nT, Bz was nominal, and the Phi angle was mostly negative.

Forecast: Weak enhancements in the solar wind environment are possible on 26-27 Feb due to potential interaction with a negative polarity, south polar extension CH HSS.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet on 25 Feb, then become unsettled through 27 Feb with possible CH HSS (negative polarity) activity. There is a slight chance for active conditions on 26-27 Feb as well if this feature becomes geoeffective.
