COMMENT: No sun spots noted on the visible disk at this time. 
The solar wind speed is presently around 400 km/s and is expected 
to remain near this speed for the next 3 days. The north-south 
component of the interplanetary magnetic field (Bz) fluctuated 
between +/-2nT.

Observed Regional daily pc3 Indices 28 Jan : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Canberra             0   (Quiet)
      Hobart               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.
