Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 054 Issued at 2200Z on 23 Feb 2009
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity was very low.  No flares were observed
during the past 24 hours.  The solar disk remains spotless.
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 at quiet to unsettled conditions.  A
continued influence of the recurrent coronal hole high speed stream
is reflected in ACE solar wind measurements.  Solar wind velocities
gradually increased from around 420 km/s to a peak of 487 km/s with
interplanetary Bz fluctuations from +5 to -5 nT.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominately quiet for the next three days (24-26
February).
