3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: Quiet.

Central Australian Regions:
 Mildly Disturbed Periods:  14-16 Mar,  20 Mar,  26-29 Mar
 Best Quiet Periods: 17-19 Mar,  21-25 Mar,  30 Mar to 9 Apr.

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.
