COMMENT: The solar wind decreased from 420 to 370 km/s and is 
expected to remain around this speed for the next three days.The 
interplanetary magnetic field (IMF) was fluctuated between +/- 
3nT. The visible solar disk is spotless at this time.

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
07 Oct   -10

Observed Australian Regional MUFs
   Equatorial PNG/Niue Region:
      Depressed by 20% during local day,
      Depressed by 35% during local night.
   Northern Australian Region:
      Depressed by 15% during local day,
      Depressed by 25% during local night.
   Southern Australian and New Zealand Region:
      Near predicted monthly values.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.

Predicted Monthly T index for October:   2

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
08 Oct     0    near predicted monthly values/depressed 10 to 
                20% 
09 Oct     0    near predicted monthly values/depressed 10 to 
                20% 
10 Oct     0    near predicted monthly values/depressed 10 to 
                20% 

COMMENT: Expect the equatorial and north Australian region to 
have slightly depressed conditions over next three days due to 
very low solar activity.
