Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Apr 05 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2813 (N21W44, Axx/alpha) exhibited decay in its trailer spots and was absent of significant flare activity. No Earth-directed CMEs were observed in available imagery.

Forecast: Solar activity is expected to be very low on 05-07 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 05-07 Apr. The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 hr Summary: The solar wind environment reflected mostly nominal conditions. At approximately 04/2300 UTC, solar wind density began to increase to 30 particles per cubic centimeter. In conjunction with this increase, total field values increased to 9 nT while Bz dropped to a low of -8 nT. Solar wind speed remained steady with a high value of ~320 km/s. Phi angle was variable throughout the reporting period. Forecast: Solar wind conditions are expected to transition from nominal to weakly enhanced on 05-07 Apr due to weak, positive-polarity CH HSS influence.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is likely to reached unsettled conditions on 05-07 Apr due to anticipated CH HSS influence.
