.Forecast… The greater than 2 MeV electron flux is expected to be normal to moderate 13-15 Feb and the greater than 10 MeV proton flux is expected to continue at background.
Solar Wind
.24 hr Summary… Solar wind parameters were indicative of a return to a slow solar wind regime. Total IMF strength weakened as it decreased from 5 nT to end of period values of 2 to 4 nT. The Bz component underwent only weak deviations. Solar wind speed decreased from 400-425 km/s to end of period speeds at ~350 km/s. The phi angle was predominantly positive.
.Forecast… A slow solar wind regime is anticipated to continue 13-15 Feb.
