Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 282 Issued at 2200Z on 09 Oct 2005 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was at very low levels. Region 813 (S08W35) continues to show steady decay in sunspot area. Region 813 remains a magnetic beta spot group. No new regions were numbered today.

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

IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z:

The geomagnetic field was at quiet to unsettled levels.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels. The coronal hole high speed stream has begun to wane but may yet produce further periods of active conditions through 10 October.
