Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 272 Issued at 2200Z on 29 Sep 2010
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  Solar activity was low.  Region 1110 (N19W45) produced
a C2/Sf flare at 28/2211Z.  This region is a D-type group with a
beta magnetic configuration.  Region 1109 (N22W24) remains an E-type
group with a beta magnetic configuration.  New Region 1111 (N23E55)
was numbered today.  The 10cm solar flux has shown a slight rise in
background levels for 29 September.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a C-class event likely.
IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was at quiet to unsettled levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly quiet for the next three days (30
September - 02 October).
