Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 027 Issued at 2200Z on 27 Jan 2006
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for an isolated C-flare from Region 848
(S20W78).
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was quiet to active. Activity was due to the
continued influence of a coronal hole high speed stream. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
