COMMENT: Solar wind parameters remain at nominal levels. Parameters 
are likely to become disturbed late on 24 or 25 due to the effects 
of a coronal hole wind stream.

      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.
