Solar Activity

24 hr Summary

Solar activity was very low. Region 2767 (S21W21, Hsx/alpha) remained quiescent. No Earth-directed CMEs were observed in available imagery.

Forecast

Solar activity is expected to remain at very low levels for the next

three days.

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 and 10 MeV proton fluxes are expected to remain below event threshold for the next three days.

Solar Wind

24 hr Summary

Solar wind parameters, as measured by the DSCOVR spacecraft, reflected nominal conditions. Total field strength averaged near 4 nT, the Bz component ranged from +/- 5 nT, and solar wind speeds were between 350-440 km/s. Phi angle remained mostly oriented in the negative sector.

Forecast

The solar wind environment is expected to continue at nominal levels for the next three days.

Geospace

24 hr Summary

The geomagnetic field was quiet.

 

Forecast

The geomagnetic field is expected to be quiet for the next three days.
