.Forecast… Very low solar activity is expected to continue 26-28 Mar.
Energetic Particle
.24 hr Summary… The greater than 2 MeV electron flux reached high levels, with a peak flux value of 1,398 pfu observed at 25/1730 UTC. The greater than 10 MeV proton flux maintained background values.
.Forecast… The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 26-28 Mar. The greater than 10 MeV proton flux is expected to continue at background levels.
Solar Wind
.24 hr Summary… Solar wind parameters returned to background levels over the period. Solar wind speed decreased to near 380 km/s, total field ranged from 2-6 nT, and the Bz component was between +5/-2 nT. Phi angle was oriented in a negative solar sector for most of the period.
.Forecast… Solar wind conditions are expected to be at or near nominal levels on 26-28 Mar.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be mostly quiet on 26-28 Mar.
