3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions:
Disturbed Periods: 3 Apr.
Best Quiet Periods: 15-22 Mar, 26 Mar, 30 Mar, 2 Apr, 6-7 Apr.
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.
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.
