Energetic Particles
.24 hr Summary… The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux was at background values.
.Forecast… The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 14-16 Jan. The greater than 10 MeV proton flux is expected to persist at background levels.
Solar Wind
.24 hr Summary… Solar wind parameters remained near background levels through the period. Solar wind speeds decreased from 450 km/s to near 380 km/s, total field strength dropped below 5 nT, and the Bz component was between +/- 5 nT. The phi angle remained solidly in a positive orientation.
.Forecast… Solar wind parameters are expected to be at mostly nominal conditions on 14-16 Jan under an ambient, background solar wind regime.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be at mostly quiet levels on 14-16 Jan.
