COMMENT: Solar wind parameters were undisturbed over the reporting 
period. Solar wind parameters are expected to be undisturbed 
on day one, becoming slightly disturbed later day two, persisting 
on day three due to coronal hole effects.

      Darwin               0   (Quiet)
      Townsville           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.
