COMMENT: Solar activity was very low over the last 24 hours. 
Similar conditions are expected for the next 2 days. The solar 
wind velocity declined from 550km/s to be 400km/s at the time 
of this report. Bz did not have any significant southward periods 
and ranged between 0-3nT.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 14 Apr: Quiet

Observed Regional daily pc3 Indices 14 Apr : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Canberra             2   (Quiet)
      Hobart              19   (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.
