2. FORECAST (02 OCTOBER - 01 NOVEMBER)
Disturbed Periods:
21 Oct.
Best Quiet Periods:
3-6 Oct, 8-9 Oct, 11-15 Oct, 17 Oct, 25 Oct, 28 Oct.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: Quiet
Central Australian Regions: Quiet
Mildly disturbed 10 Oct, 18 Oct.
Southern Australian Regions:
Disturbed Periods: 10 Oct, 18 Oct.
Best Quiet Periods: 2-8 Oct, 11-15 Oct, 20-21 Oct, 24-28 Oct.
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.
