3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: 
 Disturbed Periods: None.
 Best Quiet Periods: 4 Sep to 30 Sep

Central Australian Regions: 
 Disturbed Periods: Mildly disturbed 4 Sep, 16-18 Sep
 Best Quiet Periods: 5-15 Sep, 20-25 Sep, 28-29 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.
