Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 280 Issued at 2200Z on 07 Oct 2011
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was low. Region 1313 (S16E39) produced a
C1/Sf at 07/0121Z. Region 1305 (N11W91) continued to produce C-class
activity as it rotated around the west limb. All of the other
regions on the disk remained relatively stable during the past 24
hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a slight chance for moderate activity for the next three days
(08-10 October).
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet on day one (08 October). Quiet to
unsettled conditions are expected on days two and three (09-10
October) due to effects from a recurrent coronal hole high speed
stream.
