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 (16 SEPTEMBER - 16 OCTOBER)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 20 Sep to 23 Sep,   29 Sep,  3 Oct to 5 Oct

Best Quiet Periods: 
 16 Sep to 19 Sep,  24 Sep to 28 Sep,  30 Sep to 2 Oct,  6 Oct to 10 Oct,  
12 Oct.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 16 Sep to 10 Oct.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 16 Sep to 10 Oct.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 16 Sep to 17 Sep,  22 Sep to 10 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.
