Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 039 Issued at 2200Z on 08 Feb 2008
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was mostly quiet. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled on day 1 (09 Feb). Activity is
expected to increase to unsettled to active levels on day 2 (10 Feb)
due to a recurrent coronal hole high-speed stream. Activity is
expected to decrease to quiet to unsettled levels on day 3 (11 Feb).
