Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 281 Issued at 2200Z on 08 Oct 2010
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was very low. A few B-class events were
observed originating on the east limb near S24 in the vicinity of
old returning Region 1106 (S22, L-217).
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels for the next three days (09 - 11 October).
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was at mostly quiet levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet for days one and two (09 - 10 October).
By day three (11 October), geomagnetic activity is expected to
increase to quiet to unsettled levels, with isolated active periods
at high latitudes. The forecasted increase in activity is due to a
geoeffective coronal hole high speed stream coupled with a possible
glancing blow from the 06 October full-halo CME.
