Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Mar 29 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2812 (N21W19, Hrx/alpha) was absent of significant flare activity and overall unremarkable. No Earth-directed CMEs were observed in available imagery.

Forecast: Solar activity is expected to be very low on 29-31 Mar.

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 29-31 Mar. 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 reflected background conditions. Wind speed decreased to end the period near 320 km/s. Total field peaked at 4 nT while Bz did not drop lower than -3 nT. Phi angle was predominately negative. Forecast: The solar wind environment is expected to remain at background levels throughout the forecast period (29-31 Mar).

Geospace

24 hr Summary: The geomagnetic field was at quiet levels under a nominal solar wind regime.

Forecast: The geomagnetic field is expected to persist at mostly quiet levels throughout the forecast period (29-31 Mar).
