Disturbed Periods:
15-16 Feb.
Best Quiet Periods:

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: none
Best Quiet Periods: 13 Feb to 11 Mar.
Central Australian Regions:
Disturbed Periods: Mildly disturbed 15-Feb.
Best Quiet Periods: 13-14 Feb, 16 Feb to 11 Mar.
Southern Australian Regions:
Disturbed Periods: 15-Feb.
Best Quiet Periods: 13-14 Feb, 16 Feb to 6 Mar, 9-11 Mar.
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.
