Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 297 Issued at 2200Z on 24 Oct 2010
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was very low. Region 1117 (N22E12)
produced several B-class flares during the past 24 hours. New Region
1119 (N22W22) was numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low with a chance of C-class flares from Region 1117 or
Region 1115 (S29W52) on days 1-3 (25 - 27 October).
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
Geomagnetic activity was mostly unsettled to active due to the
effects of a recurrent coronal hole high speed stream. Solar wind
speeds observed at the ACE spacecraft were at or above 600 km/s for
most of the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at mostly unsettled levels on days one and two (25 -
26 October) due to coronal hole effects. Day three (27 October) will
see quiet to unsettled levels as the coronal hole effects subside.
