Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 314 Issued at 2200Z on 10 Nov 2005

IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been very low. There are no spots visible today in Region 820 (S16W94) as it rotates around the west side of the solar disk.

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

IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels. Isolated active conditions are possible for 11 November due to coronal hole effects.
