Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 124 Issued at 2200Z on 03 May 2008
IA.  Analysis of Solar Active Regions and Activity from  02/2100Z
to 03/2100Z:  Solar activity was at very low levels.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field was at quiet to unsettled levels.  Wind speed
measured at the ACE spacecraft reached a maximum of 580 km/s at
03/2022Z and Bz ranged between +/- 7.  ACE signatures indicated that
Earth had entered a coronal hole high speed stream at approximately
03/1200Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels.  There is a slight
chance for isolated active levels at middle latitudes and minor
storm conditions at high latitudes due to a high speed stream
throughout the forecast period (04 - 06 May).
