Report of Solar-Geophysical Activity
Issued: 2006 Apr 09 2200 UTC
Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Environment Center and the U.S. Air Force.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 099 Issued at 2200Z on 09 Apr 2006
IA.  Analysis of Solar Active Regions and Activity from  08/2100Z
to 09/2100Z:  Solar activity was very low.  Region 865 has rotated
around the west limb.  All other regions have remained quiescent.
No new regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was at quiet to minor storm levels, with major
storming at high latitudes.  The geomagnetic storm was the result of
a co-rotating interaction region preceding the high speed stream
from a coronal hole.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled to active with a chance for minor storm
conditions on 10 April.  Quiet to unsettled conditions are expected
on 11 - 12 April.
