Quiet to Unsettled conditions. Isolated Active periods 27Aug 
due to extended southward IMF caused by a CME impact.

 3 Sep,  5 Sep,    9-16 Sep,  18-23 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 1- 27Sep.

Central Australian Regions:
 Mildly disturbed Periods: 28-29 Aug.
 Best Quiet Periods: 3-6 Sep,  10 - 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.
