Observed Regional daily pc3 Indices 05 Oct : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)

      Canberra             2   (Quiet)
      Hobart               4   (Quiet)
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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and Space Environment Research Center, Japan.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY

Date   T index
05 Oct    -8

Observed Australian Regional MUFs
   Equatorial PNG/Niue Region:
      Depressed by 10-20%.
   Northern Australian Region:
      Depressed by 20%.
   Southern Australian and New Zealand Region:
      Depressed by 10-15%. 
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Depressed by 15% during the local day. 
      Near predicted monthly values during local night
      when trace is visible on the ionogram.

Predicted Monthly T index for October:  10

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
06 Oct    -5    depressed 10 to 20%/near predicted monthly values 
07 Oct    -5    depressed 10 to 20%/near predicted monthly values 
08 Oct     0    Near predicted monthly values 
COMMENT: HF conditions were were most likely depressed due to 
low ionisation of the ionosphere.
