Quiet to unsettled conditions.

2. FORECAST (01 SEPTEMBER - 01 OCTOBER)
Disturbed Periods: 
25-28 Sep.

Best Quiet Periods: 
 9-12 Sep, 14-16 Sep, 22-24 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 13-19 Sep,  21-26 Sep.

Southern Australian Regions:
 Disturbed Periods: 26-27 Sep.
 Best Quiet Periods: 09-18 Sep,  22-25 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.
