to 08/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is forecast to be very
low for the next 3 days (09-11 December).
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
forecast to be mostly quiet day 1 (09 December), quiet to unsettled
on day 2 (10 December), and quiet to unsettled with the chance for
active conditions on day 3 (11 December). Activity is forecast due
to recurrent coronal hole effects anticipated to begin late on day 2
