Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 270 Issued at 2200Z on 27 Sep 2006
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was at very low levels.  Region 911
(N07E59) has a single sunspot and is the only spotted group on the
visible disk.  No new regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was at quiet to unsettled 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 unsettled levels throughout the period.
