Quiet to unsettled conditions. 2. FORECAST (04 AUGUST - 03 SEPTEMBER) Disturbed Periods: 17 Aug. Best Quiet Periods: 5-6 Aug, 9-10 Aug, 13 Aug, 21 Aug, 25-26 Aug. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 4-30 Aug. Central Australian Regions: Disturbed Periods: None. Best Quiet Periods: 4-30 Aug. Southern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 4-17 Aug, 20-27 Aug. 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.
