2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 07 Feb: Quiet to Unsettled 

Estimated Indices 07 Feb :  A   K

Observed Regional daily pc3 Indices 07 Feb : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Camden              24   (Quiet to unsettled)
      Canberra             0   (Quiet)
      Hobart               0   (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.

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