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.

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

Predicted Monthly T index for August:   2

COMMENT: Ionospheric conditions were mostly normal over the UT 
day. Some variable depressions were seen in the Equatorial/N 
Aus regions during the local day. Expect mostly normal conditions 
next three days with continuing daytime depressions in the
Equatorial/N Aus region.
