3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 29 Aug to 3 Sep, 5-9 Sep, 14-16 Sep, 19-24 Sep.
Central Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 29 Aug to 3 Sep, 5-9 Sep, 14-16 Sep, 19-24 Sep.

Best Quiet Periods: 29 Aug to 9 Sep, 14-16 Sep, 20-24 Sep.
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.
PLEASE NOTE:
Geomagnetic activity can frequently be determined by short timescale
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
