Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Apr 09 1230 UTC.

Solar Activity

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

Forecast: Solar activity is expected to be very low on 09-11 Apr.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was normal to moderate and the greater than 10 MeV proton flux was at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 09-11 Apr. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were indicative of waning CH HSS influence. Solar wind speed decreased from approximately 475-400 km/s. Total field ranged from 1-5 nT while the Bz component was between +/-3 nT. Phi angle was mostly positive.

Forecast: Solar wind parameters are expected to be at nominal levels for the rest of 09 Apr. By late on 10 Apr through 11 Apr, a weak connection with a negative polarity CH HSS is possible.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be quiet on 09 Apr. Weak HSS effects are possible on 10-11 Apr causing unsettled periods.
