Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 335 Issued at 2200Z on 01 Dec 2007

IA. Analysis of Solar Active Regions and Activity from 30/2100Z to 01/2100Z: Solar activity was very low. New Region 976 (S09E27) is classified as a Bxo group, with magnetic class beta.

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

IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet through the forecast period.
