Observed Regional daily pc3 Indices 03 DEC : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Canberra            38   (Quiet to unsettled)
      Hobart              61   (Active)
Pc3 pulsations are high frequency (10-45 second period) variations 
of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.

Estimated AFr/Ap Indices 03 Dec : A 
           Fredericksburg         6
           Planetary              5                         

Observed AFr/Ap Indices 02 Dec :  A   K
           Fredericksburg         6
           Planetary              4   1001 2321     


2B. MAGNETIC FORECAST 
Date      Ap    Conditions
04 Dec    12    Quiet to unsettled with isolated active periods. 
05 Dec    12    Quiet to unsettled with isolated active periods. 
06 Dec     8    Quiet to Unsettled 
COMMENT: Solar wind data parameters suggest the Earth is presently 
under the influence of a relatively slow coronal hole wind stream 
which may produce isolated active periods for 4-5 December.
