Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 311 Issued at 2200Z on 07 Nov 2011
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was low. Only low to mid-level C-class
activity was observed from both Regions 1338 (S13W12) and 1339
(N18E05). Both regions exhibited some growth in area and spot count
with Region 1338 developing a Beta-Gamma magnetic configuration.
There were no Earth-directed CMEs observed during the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be
moderate during the period (08 - 10 November) with a slight chance
for high activity (M5 or higher) from Region 1339. There is also a
slight chance for a proton flare from this region during the period.
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was at quiet to unsettled levels. Solar wind
speeds ranged between 300 to 375 km/s while the Bz component of the
interplanetary magnetic field did not vary much beyond +/- 5 nT.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels during the period (08 - 10 November).
