3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 19-28 Jan, 30 Jan to 13 Feb.
Central Australian Regions:
Disturbed Periods: None.
Mildly Disturbed Periods: None.
Best Quiet Periods: 19-24 Jan, 31 Jan to 05-Feb, 08-Feb to 12-Feb.

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.
