NOTE: Indices may have been generated from data obtained in 
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.
