Observed Regional daily pc3 Indices 30 Aug :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (Quiet)
Camden 4 (Quiet)
Gnangara 11 (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.
Estimated AFr/Ap Indices 30 Aug : A

Near predicted monthly vaules during local night.
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 during local day,
Enhanced by 25% during local night.

next three days with continuing daytime depressions in the
Equatorial/N Aus region.
