Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 170 Issued at 2200Z on 19 Jun 2007
IA.  Analysis of Solar Active Regions and Activity from  18/2100Z
to 19/2100Z:  Solar activity was very low.  There are no spots on the
visible disk.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low.
IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet to unsettled.  The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from unsettled to minor storm levels on 20-22 June
as a recurrent coronal hole becomes geoeffective.  The influence of
the coronal hole high speed stream could lead to isolated major
storm periods at high latitudes.
