3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 2 Dec to 4 Dec, 9 Dec to 19 Dec, 24 Dec to 26 Dec.
Southern Australian Regions:

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.
