Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 269 Issued at 2200Z on 26 Sep 2010
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  Region 1109 (N21E14)
produced several B-class flares during the period and has grown in
both areal coverage and spot count.  The region has maintained its
E-type sunspot classification and is a beta magnetic configuration. 
New Region 1110 (N19W07) was numbered today and is magnetically
classified as an alpha group.
IB.  Solar Activity Forecast:  Solar activity is expected to be low. 
Region 1109 is likely to produce C-class flares with a slight chance
for a M-class event.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was predominantly quiet.  Unsettled levels were
observed at mid-latitudes during the period between 26/1200-1500Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at predominately quiet levels with isolated unsettled
periods for the next three days (27-29 September) due to the
continued influence of a high speed wind stream.
