Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 276 Issued at 2200Z on 03 Oct 2006

IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity was very low.

IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels.

IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today.
