Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity was very low. Region 977 (S06E40) has developed slightly and is now classified as a Cso spot group. IB. Solar Activity Forecast: Solar activity is expected to be very low through the forecast period (04 -06 December). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: 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 (04 - 06 December). III.
