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.

06 Mar     4    Quiet 
07 Mar     4    Quiet 
08 Mar     4    Quiet 
COMMENT: The Bz component of the interplanetary magnetic field 
was mildly negative for the first few hours of the UT day, settling 
to neutral for the remainder of the day. Regional geomagnetic 
conditions at low to mid latitudes were quiet. At high latitudes 
conditions were unsettled at first, becoming quiet later in the 
day. Expect generally quiet conditions next three days.

Observed Australian Regional MUFs
   Equatorial PNG/Niue Region:
      Near predicted monthly values during local day,
      Depressed by 15% during local night.
      Depressed by 20% after local dawn.
   Northern Australian Region:
      Depressed by 20% during local day,
      Near predicted monthly values during local night.
   Southern Australian and New Zealand Region:
      Near predicted monthly values.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Depressed by 15% over the UT day.

Predicted Monthly T index for March:   3

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
06 Mar   -10    near predicted monthly values/depressed 10 to 
                20% 
07 Mar   -10    near predicted monthly values/depressed 10 to 
                20% 
08 Mar   -10    near predicted monthly values/depressed 10 to 
                20% 
COMMENT: Strong enhancement lasting 2-3 hours observed along 
the dusk terminator, mainly Equatorial/N Aus regions, also evident 
as a mild enhancement at mid-Aus latitudes. Weak ionosphere at 
times in S ocean/Antarctic regions.
