Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 018 Issued at 2200Z on 18 Jan 2009
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity was very low. No flares were observed
during the past 24 hours. The visible disk continued to be spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled on 19-20 January. During this
period, isolated active periods are possible at high latitudes due
to a recurrent coronal hole high-speed stream. Predominantly quiet
conditions are expected to return late on 20 January as the
high-speed stream subsides.
