Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 318 Issued at 2200Z on 13 Nov 2008


IA. Analysis of Solar Active Regions and Activity from 12/2100Z
to 13/2100Z: Solar activity was very low. Region 1008 (N33W38)
appears quiet and stable.
IB. Solar Activity Forecast: Solar activity is expected to be very
low during the forecast period. There is a slight chance of a C-
class flare from Region 1008.
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels in the past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet with isolated unsettled conditions possible
during the forecast period.
