Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 007 Issued at 2200Z on 07 Jan 2007

IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity continues at very low levels. The four active regions on the visible disk are stable or in decay.

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

IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: 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 with isolated unsettled periods.
