Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 325 Issued at 2200Z on 21 Nov 2006
IA.  Analysis of Solar Active Regions and Activity from  20/2100Z
to 21/2100Z:  Solar activity was very low. A CME was observed in
LASCO imagery at 21/0554 UTC from behind the east limb. This event
is not expected to be geoeffective.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 20/2100Z to 21/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet on 22 November. On 23 and 24 November, active to
minor storm periods are possible, as a recurrent coronal hole high
speed stream moves into a geoeffective position.
