Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 076 Issued at 2200Z on 17 Mar 2007
IA.  Analysis of Solar Active Regions and Activity from  16/2100Z
to 17/2100Z:  Solar activity was very low. No flares were observed
during the past 24 hours and the solar disk continues to be
spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 16/2100Z to 17/2100Z:
The geomagnetic field was quiet to unsettled. Solar wind speed
declined gradually during the past 24 hours from initial values
around 630 km/s to values around 520 km/s at forecast issue time.
The greater than 2 MeV electron flux was high during the past 24
hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (18-20 March).
