Solar Activity
.24 hr Summary...
Solar activity was very low and the solar disk was without spots. No
Earth-directed CMEs were observed in available coronagraph imagery.
.Forecast...
Solar activity is expected to be at very low levels over 19-21 Sep.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels.
The greater than 10 MeV proton flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels on
19-21 Sep. The greater than 10 MeV proton flux is expected to persist at
background levels through 21 Sep.
Solar Wind
.24 hr Summary...
Solar wind parameters persisted at background levels this period. Total
magnetic field strength averaged near 6 nT, and the north-south (Bz)
component ranged between +/- 5 nT. Solar wind speeds averaged ~430 km/s.
The phi angle was predominantly negative.
.Forecast...
Ambient solar wind conditions are expected to prevail over 19-21 Sep.
Geospace
.24 hr Summary...
The geomagnetic field was quiet with an isolated period of unsettled
conditions.
.Forecast...
