Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 100 Issued at 2200Z on 10 Apr 2009
IA.  Analysis of Solar Active Regions and Activity from  09/2100Z
to 10/2100Z:  Solar activity was very low. No flares occurred during
the past 24 hours. The solar disk continues to void of sunspots.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z:
The geomagnetic field was quiet to unsettled during the past 24
hours. Solar wind velocity continued to increase but appears to be
leveling out at this time in the range between 500-540 km/s. The
interplanetary magnetic field Bz component fluctuated between +/- 4
nT. The signatures in the solar wind continue to be consistent with
a high speed stream from a coronal hole.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days.
