Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 002 Issued at 2200Z on 02 Jan 2012
IA.  Analysis of Solar Active Regions and Activity from  01/2100Z
to 02/2100Z:  Solar activity was low. A few nominal C-class flares
occurred. New Region 1391 (N13E81) was numbered today as it rotated
around the East limb.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low with a slight chance for an M-class flare for the next 3
days (3-5 January).
IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was mostly quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet for day 1 (3 January). Activity is
forecast to increase to mostly unsettled conditions with possible
active periods on day 2 (4 January) with an anticipated solar sector
boundary crossing (SSBC). Conditions should return to mostly quiet
on day 3 (5 January).
