Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 332 Issued at 2200Z on 28 Nov 2006
IA.  Analysis of Solar Active Regions and Activity from  27/2100Z
to 28/2100Z:  Solar activity was very low. Today's largest event was
a B4 from Region 926 (S10E35) at 1510Z, which was accompanied by a
type II radio sweep. Region 926 has a relatively simple magnetic
configuration and does not appear to be growing at this time. Region
927 (N10E46) continues to grow steadily but only produced a few,
low-level B-class events during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be
predominantly very low for the next three days (29 November - 1
December). There is a chance, however, for an isolated C-class event
from 926 or 927.
IIA.  Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field was mostly quiet during the past 24 hours. The
greater than 2 MeV electron flux was at high levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly quiet for the next three days.
