G0 conditions. 2. FORECAST (23 JUNE - 23 JULY) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 24-25 Jun, 13-14 Jul, 17-Jul, 22-23 Jul Best Quiet Periods: 23-Jun, 27-Jun to 11-Jul, 16-Jul, 19-21 Jul. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 23 Jun to 23 Jul. Central Australian Regions: Mildly disturbed Periods: 25-27 Jun, 13-17 Jul, 23-Jul. Best Quiet Periods: 23-Jun, 28-Jun to 12-Jul, 18-22 Jul. Southern Australian Regions: Disturbed Periods: 25-27 Jun, 13-17 Jul, 23-Jul. Best Quiet Periods: 23-Jun, 28-Jun to 12-Jul, 18-22 Jul. 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.
