Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Feb 28 1230 UTC.

Solar Activity

24 hr Summary: The visible disk remained spotless, keeping solar activity at very low levels. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to remain very low on 28-29 Feb and 01 Mar.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected reach moderate levels on 28-29 Feb and moderate to high levels on 01 Mar due to HSS influence. The greater than 10 MeV proton flux is expected to continue at background values.

Solar Wind

24 hr Summary: Solar wind parameters remained near background levels. Solar wind speeds ranged from 320 - 380 km/s, total field fluctuated from 1-7 nT, and the Bz component varied between +/-4 nT. Phi was mostly negative for the majority of the period before rotating to a mostly positive orientation after 28/0600 UTC.

Forecast: Near background conditions are expected through 28 Feb. An enhancement in solar wind parameters is expected early on 29 Feb, lasting through 01 Mar as an equatorial, negative polarity CH HSS moves into a geoeffective position.

Geospace

24 hr Summary: The geomagnetic field was at quiet levels.

Forecast: The geomagnetic field is expected to be mostly quiet on 28 Feb. On 29 Feb through 01 Mar, field conditions are expected to be at quiet to unsettled levels, with isolated active intervals likely on 01 Mar. This increase in activity is due to negative polarity CH HSS influence.
