COMMENT: New region 961, located at S09 E77 is magnetically simple. 
A coronal hole is now located at central meridian. The solar 
wind speed has averaged around 430 km/s over the last 24 hours 
and is approximately 410 km/s at present.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 25 Jun: Quiet

Observed Regional daily pc3 Indices 25 Jun : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Camden              25   (Quiet to unsettled)
      Canberra             0   (Quiet)
      Hobart               9   (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.
