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 (16 AUGUST - 15 SEPTEMBER)
Disturbed Periods: 26 to 29 Aug, 3 to 4 & 11 to 13 Sept.

Best Quiet Periods: 18 to 25 Aug, 5 to 10 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 16 Aug to 25 Aug, 5 Sep to 9 Sep.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 16 Aug to 25 Aug,  29 Aug to 31 Aug,  5 Sep to 10 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.
