Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 297 Issued at 2200Z on 24 Oct 2006
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was at very low levels today.  Both
spotted regions 917 (S05W73) and 918 (S04W85) have undergone slow
decay during the period.  No new regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field was at quiet to unsettled levels.  Solar wind
speed dropped down to approximately 400 km/s as the coronal hole
moves out of geoeffective position.  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 unsettled levels throughout the period.
