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:
Depressed by 15% during local day,
Near predicted monthly values during local night.
Depressed by 25% after local dawn.
Northern Australian Region:
Depressed by 15% 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 20% during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Enhanced by 20% over the UT day.
Predicted Monthly T index for July: 4
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
30 Jul 0 near predicted monthly values/depressed 10 to
20%
31 Jul 0 near predicted monthly values/depressed 10 to
20%
01 Aug 0 near predicted monthly values/depressed 10 to
20%
COMMENT: Mostly normal HF conditions observed over the last 24
hours. Depressed periods during local day for Northern AUS/Equatorial
regions. Normal conditions for Southern AUS/NZ regions with continued
enhancements during local night. Slightly enhanced conditons
in the antarctic region, however, periods without a trace were
noted on some ionograms. Expect similar conditions for the next
3 days.
