Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 324 Issued at 2200Z on 20 Nov 2009
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity has been at very low levels for the past
24 hours. Region 1033 (N21E23), a Bxo-beta, has continued to grow in
size and sunspot number. Region 1032 (N16W03), a Bxo-beta, has shown
a slight decay in spots and area. No flares were observed.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels with a slight chance for a C-class flare.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled with a slight chance for an active period
on day one (21 November) due to a recurrent coronal hole high-speed
stream. Conditions are expected to be predominantly at quiet levels
for day two and three (22-23 November).
