Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 163 Issued at 2200Z on 12 Jun 2007
IA.  Analysis of Solar Active Regions and Activity from  11/2100Z
to 12/2100Z:  Solar activity was very low.  Region 960 (S05W71)
continues to decay and is now classified as a magnetic alpha sunspot
group.   It produced a B3 flare at 12/1931Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.  There remains a chance for an isolated C-class flare from
Region 960.
IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet on 13 June.  Expect quiet to active conditions,
with isolated minor storm periods possible at high latitudes, on
14-15 June as a recurrent coronal hole rotates into a geoeffective
position.
