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.

      03-06, 12-15 UT at Brisbane and 11-17 UT at Norfolk
      Is. Night spread F observed at both stations.
      Enhancements to 40% at other stations 08-20 UT.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
