2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 29 Aug: Mostly quiet.

Observed Regional daily pc3 Indices 29 Aug : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            3   (Quiet)
      Camden               8   (Quiet)
      Canberra             0   (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.

31 Aug     5    Quiet 
01 Sep    14    Quiet to unsettled with isolated active periods 
                possible. 

COMMENT: Magnetic activity is expected to increase on 1 September 
due to the effects of a recurrent coronal hole.
