Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 321 Issued at 2200Z on 17 Nov 2007
IA.  Analysis of Solar Active Regions and Activity from  16/2100Z
to 17/2100Z:  Solar activity was very low.  Region 974 (N13W21) was
classiefied as a Dao, Beta-Gamma magnetic type at 0300Z.  Subsequent
reports have identified it as a spotless plage region.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low.  There is a slight chance of an isolated C-Class flare
from region 974.
IIA.  Geophysical Activity Summary 16/2100Z to 17/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to remain predominantly quiet during 18-19 Nov, increasing
to unsettled to occasionally active by 20 Nov as a recurrent coronal
hole high speed stream becomes geoeffective.
