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 International Center for Space Weather 
Science and Education, Japan.


No significant geomagnetic activity observed during the week, with
ASWAS G0 conditions throughout the week. A slight increase in activity 
was observed on 09-Oct induced by a solar coronal hole wind stream.

2. FORECAST (13 OCTOBER - 12 NOVEMBER)
Disturbed Periods: 
24,30 Oct and 05 Nov (less than ASWAS G1).

Best Quiet Periods: 
 13-19 Oct,  22-23 Oct,  25-26 Oct, 07-12 Nov.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
 Disturbed Periods: None
 Best Quiet Periods: 13-14-Oct, 19-23-Oct, 08-10-Nov

Central Australian Regions:
 Mildly Disturbed Periods:25-27-Oct, 31-Oct to 05-Nov
 Best Quiet Periods: 13-14-Oct, 19-23-Oct, 08-10-Nov

Southern Australian Regions:
 Disturbed Periods: 25-27-Oct, 31-Oct to 05-Nov
 Best Quiet Periods: 13-14-Oct, 19-23-Oct, 08-10-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.
