SDF Number 031 Issued at 2200Z on 31 Jan 2010
IA. Analysis of Solar Active Regions and Activity from 30/2100Z
to 31/2100Z: Solar activity was very low. Region 1041 (S27E24) is
spotless today. Region 1043 (N25E24) is a D-type spot group with a
beta magnetic classification. This region has produced several
low-level B-type flares during the last 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low with a chance for a C-flare from Region 1043.
IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was quiet.
