Antarctic Division and International Center for Space Weather 
Science and Education, Japan.

Mostly Quiet to unsettled conditions observed.

2. FORECAST (31 OCTOBER - 30 NOVEMBER)
Disturbed Periods: 31 Oct - 1 Nov.

Best Quiet Periods: 14-26 Nov.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: 31 Oct - 1 Nov.
 Best Quiet Periods: 2-26 Nov.

Central Australian Regions:
 Disturbed Periods: 31 Oct - 1 Nov.
 Best Quiet Periods: 2-26 Nov.

Southern Australian Regions:
 Disturbed Periods: 31 Oct - 1 Nov.
 Best Quiet Periods: 6-10 Nov,  12-26 Nov.


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.
