SDF Number 049 Issued at 2200Z on 18 Feb 2006
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity remains at very low levels.  No sunspots
are visible on the disk.
IB.  Solar Activity Forecast:  Solar activity is expected to continue
at very low levels.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
The geomagnetic field was at quiet levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels.  Active conditions are
possible on 19 February due to a favorably positioned coronal hole
high speed solar wind stream.
