Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 273 Issued at 2200Z on 30 Sep 2010
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was very low.  Region 1109 (N21W39)
produced several B-class events.  Region 1109 has decreased in areal
coverage and extent and is now a Dhi group with a beta magnetic
configuration.  Region 1110 (N19W60) has also decreased in areal
coverage and is now a Bxo group with a beta magnetic configuration. 
Region 1111 (N24E42) is an A-type group with one spot.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with C-class activity likely.
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
The geomagnetic field was quiet during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for days one and two (01-02 October).  Mostly
quiet with a slight chance for isolated unsettled periods are
expected for day three (03 October) due to recurrent activity.
