cooperation with the following organisations: Geoscience Australia,
University of Newcastle Space Physics Group, Australian Government
Antarctic Division and Space Environment Research Center, Japan.
Quiet to unsettled conditions.
2. FORECAST (02 SEPTEMBER - 02 OCTOBER)
Disturbed Periods:
No strong recurrent patterns, however Unsettled-Active may be experienced on:
5-7 Sept, 20-23 Sept
Best Quiet Periods:
2 Sep to 4 Sep, 8 Sep to 19 Sep, 24 Sep to 28 Sep.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 2 Sep to 20 Sep.
Central Australian Regions:
Disturbed Periods: Mildly disturbed 20-24 Sept
Best Quiet Periods: 2 Sep to 19 Sep.
Southern Australian Regions:
Disturbed Periods: 20-24 Sept
Best Quiet Periods: 2 Sep to 11 Sep, 16 Sep to 20 Sep.
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.
