Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 001 Issued at 2200Z on 01 Jan 2006
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was mostly quiet. An 8 nT sudden impulse was
observed at the Boulder magnetometer at 01/1406 UTC. The greater
than 2 MeV electron flux at geosynchronous orbit was at high levels
again today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
