Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 296 Issued at 2200Z on 23 Oct 2006
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity has been very low.  New region 918
(S04W72) was numbered today.  LASCO imagery shows a CME on the East
limb, apparently originating from the backside.  This event 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 has been quiet.  Solar wind speed remains
elevated due to a recurrent coronal hole high speed stream.  Its
current speed is approximately 500 km/s.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet.
