Solar activity
24 h Summary
Solar activity was very low. The visible disk was spotless. No
Earth-directed CMEs were observed in available coronagraph imagery.
Forecast
Solar activity is expected to be at very low levels on 14-16 Dec.
Energetic Particles
24 h Summary
The greater than 2 MeV electron flux was at normal levels and the
greater than 10 MeV proton flux was at background levels.
Forecast
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels on 14-16 Dec. The greater than 10 MeV proton flux
is expected to persist at background levels throughout the period.
Solar Wind
24 h Summary
Solar wind parameters, as measured by the ACE spacecraft, reflected
nominal conditions. Solar wind speeds averaged near 375 km/s. Total
field was between 1-6 nT. Phi angle was variable.
Forecast
Solar wind parameters are expected to remain at nominal levels over
14-16 Dec.
Geospace
24 h Summary
The geomagnetic field was at quiet levels.
Forecast
The geomagnetic field is expected to be quiet 14-16 Dec.
