cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and Space Environment Research Center, Japan.

Quiet to unsettled conditions.

2. FORECAST (07 OCTOBER - 06 NOVEMBER)
Disturbed Periods: No strong recurrent patterns, however mild
 activity may be experienced on: 10 Oct, 14 Oct, 21 Oct to 22 Oct and
 2 Nov to 3 Nov.

Best Quiet Periods: 
 7 Oct to 9 Oct, 11 Oct to 13 Oct, 15 Oct to 20 Oct, 23 Oct to 1 Nov.
 and 4 Nov to 6 Nov.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 7 Oct to 6 Nov.

Central Australian Regions:
 Mildly Disturbed Periods: 21 Oct to 26 Oct.
 Best Quiet Periods: 7 Oct to 20 Oct and 27 Oct to 6 Nov.

Southern Australian Regions:
 Disturbed Periods: 21 Oct to 26 Oct
 Best Quiet Periods: 7 Oct to 20 Oct and 27 to 6 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.
