ASWAS G0 conditions observed all week.

2. FORECAST (24 NOVEMBER - 24 DECEMBER)
Disturbed Periods: 
24-25 Nov,  29-30 Nov, 04-Dec.

Best Quiet Periods: 
 2-3 Dec,  6-7 Dec,  9-19 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
 Disturbed Periods: None
 Best Quiet Periods: 24-Nov to 24-Dec

Central Australian Regions: 
 Mildly disturbed periods: 25-26 Nov and 30-Nov
 Best Quiet Periods: 06-20 Dec.

Southern Australian Regions:
 Disturbed Periods: 25-26 Nov and 30-Nov
 Best Quiet Periods: 06-20 Dec.


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.
