Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 321 Issued at 2200Z on 16 Nov 2008
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity was very low. Region 1008 (N33W78) continues to decay, presently a one spot HSX, alpha. No flares were observed during the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be very low. There is a slight chance for a C-class flare from Region 1008.
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was mostly quiet. Two active periods were observed from 0000 to 0600 UTC.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet with isolated periods of unsettled conditions.
