Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 298 Issued at 2200Z on 25 Oct 2009
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was low. Region 1029 (N14W12) produced
several B-class events and a C1.5 flare at 25/0226Z. Region 1028
(N24W10) continues to decay.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a slight chance of an M-class flare.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
Geomagnetic field activity was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  Geomagnetic activity is
expected to be quiet through the forecast period (26-28 October) due
to the coronal hole high speed stream rotating out of a geoeffective
position.
