Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 008 Issued at 2200Z on 08 Jan 2007

IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity continues at very low levels. There was no significant activity from any of the active regions on the visible disk. New Region 937 (S14E07) was numbered today.

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

IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels again today.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled.
