SDF Number 337 Issued at 2200Z on 03 Dec 2010
IA. Analysis of Solar Active Regions and Activity from 02/2100Z
to 03/2100Z: Solar activity has been at very low levels for the past
24 hours. Region 1131 (N31E53) has grown in area but has remained
magnetically classified as an Alpha group. Region 1130 (N12W67) has
entered the decay phase with a decrease in areal coverage and
sunspot number.
IB. Solar Activity Forecast: Solar activity is expected to be at
very low levels with a chance for C-class activity for the next
three days (04-06 December).
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet levels for the next three days (04-06
December).
