Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 329 Issued at 2200Z on 25 Nov 2010
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity has been very low. New Region 1128
(S16E59) was numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for an isolated C-class event.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field has been quiet. Solar wind speed has remained
steady at approximately 450 km/s throughout the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for days one and two (26-27 November). Day
three (28 November) is expected to be predominately quiet with a
slight chance for isolated unsettled periods. The increase in
activity is forecast due to the CME observed on 24 November becoming
geo-effective.
