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.

Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Vanimo frequencies were near predicted 00-06, 21 UT;
depressed to 45% 07-15 UT. Blanketing sporadic E
observed 17-20 UT. Frequencies were mostly near
predicted at Niue with depressions to 30% 01-02, 04-05
and 21-22 UT.
Northern Australian Region:
Near predicted to 30% depressed 00-10 UT, then near
predicted monthly values. Some night spread F
observed.
Southern Australian and New Zealand Region:
Mostly near predicted monthly values. Enhancements to
45% observed at some stations 08-21 UT. Night spread F
observed at some stations.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Near predicted to 30% depressed.
Predicted Monthly T index for August: 2
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
05 Aug 0 Mostly near predicted monthly values. Occasional
depressions to 30% possible.
06 Aug 0 Mostly near predicted monthly values. Occasional
depressions to 30% possible.
07 Aug 0 Mostly near predicted monthly values. Occasional
depressions to 30% possible.
COMMENT: Spread F may degrade night communications at times.
