Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 327 Issued at 2200Z on 23 Nov 2006
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity has been very low.  LASCO imagery shows
a CME on the Southwest limb at 23/1331Z.  Plane of sky speed is
approximately 550 km/s.  This event appears to originate from the
backside and is not expected to be geoeffective.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was quiet to active with one period of minor
storming.  This activity is due to a recurrent coronal hole high
speed stream rotating into a geoeffective position.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to active from 24 - 26 November.  There
is the possibility of isolated periods of minor storming for the
entire forecast period.
