Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 297 Issued at 2200Z on 24 Oct 2007
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was at very low levels.  The visible
solar disk remained spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field was at quiet levels.  The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to active levels due to a coronal hole high
speed stream rotating into a geoeffective position on day one (25
October).  Minor storm periods at middle latitudes and major storm
periods at high latitudes are possible throughout the forecast
period (25 - 27 October).
