Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 155 Issued at 2200Z on 04 Jun 2006
IA.  Analysis of Solar Active Regions and Activity from  03/2100Z
to 04/2100Z:  Solar activity continues at very low levels. B-class
flares were observed from newly numbered Region 892 (S08E67). This
new region rotated into view today as a small, but moderately
complex sunspot cluster.
IB.  Solar Activity Forecast:  Solar activity is expected to continue
at very low levels. There is a slight chance of a C-class flare from
Region 892.
IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to minor storming. Quiet to unsettled
conditions are expected on 05 and 06 May. A large recurrent coronal
hole is expected to rotate into a geoeffective position on 07 May
and produce active to minor storm periods.
