Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 251 Issued at 2200Z on 08 Sep 2009
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was very low. A weak B-level event was
seen in GOES x-rays at approximately 1701Z, which was associated 
with a brightening of plage region 1025(N17W73). The solar disk was
otherwise void of activity and continues to be spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next three days (9-11 September).
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for day one (9 September), due to
a recurrent coronal high speed stream. On day two and day three
(10-11 September), the geomagnetic field is expected to return to
quiet levels.
