SDF Number 318 Issued at 2200Z on 14 Nov 2006

IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z

Solar activity was very low. Region 923 (S05W05) produced occasional B-class flares. This region maintains it's considerable size, but has become magnetically less complex over the past 48 hours. Magnetic field maps confirm the sunspot cluster near the southeast limb is two separate regions. Both these regions, 924 (S08E44) and 925 (S06E52), are small with simple magnetic configurations.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low. There is a chance for a C-class flare from Region 923.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
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 on 15 November. A recurrent high speed stream is expected to produce occasional unsettled to active periods on 16 and 17 November.
