Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Apr 01 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low with a spotless visible disk. No Earth-directed CMEs were visible in available satellite imagery.

Forecast: Solar activity is expected to be very low on 01-03 Apr.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected to reach moderate levels on 01-03 Apr. The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters, measured at the DSCOVR spacecraft, reflected persistent influence from a weak, negative polarity CH HSS. Solar wind speeds increased from 350-415 km/s. Total field ranged from 1-8 nT while the Bz component observed a maximum southward deviation of -6 nT. Phi was predominantly negative throughout the period.

Forecast: Near ambient conditions are expected for 01-03 Apr under a background solar wind regime.

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels as weak, negative polarity CH HSS effects lingered.

Forecast: Mostly quiet conditions are expected to prevail 01-03 Apr under a background solar wind regime. Occasional unsettled conditions are possible if any of the small, isolated positive polarity coronal holes near the equator actually persist long enough to connect with the Earths magnetic field lines.
