Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 039 Issued at 2200Z on 08 Feb 2012
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was low. Region 1410 (N16W90) produced a
slow rise and fall, limb event, C7 x-ray flare at 07/2216Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low for the next 3 days (09-11 February).
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was mostly unsettled over the period due to
elevated ambient solar wind speeds and periods of southward Bz.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet to unsettled with isolated active
periods for days 1-2 (09-10 February) due to coronal hole effects.
Conditions should return to mostly quiet levels on day 3 (11
February).
