Observed Regional daily pc3 Indices 24 Nov : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            4   (Quiet)
      Camden              10   (Quiet)
      Canberra            19   (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.
