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.

A CME impact on 06-Oct produced prolonged geomagnetic storm conditions,
likely due to additional glancing impacts during the period 06-08 Oct.
G1 conditions were observed in the Australian region on 07-Oct. G3 
planetary conditions were observed on 08-Oct, G2 planetary conditions
were observed on 07-Oct and G1 planetary conditions were observed on 06-Oct
and 09-Oct. G0 conditions were observed over 01-05 Oct.

2. FORECAST (10 OCTOBER - 09 NOVEMBER)
Disturbed Periods: 
 10-17 Oct, 21-23 Oct, 02-04 Nov and 09-Nov

Best Quiet Periods: 
 19-20 Oct, 25-31 Oct, 06-07 Nov

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

Central Australian Regions:
 Disturbed Periods: 10-13 Oct
 Best Quiet Periods: 16-31 Oct and 01-09 Nov.

Southern Australian Regions:
 Disturbed Periods: 10-15 Oct, 22-23 Oct, 02-04 Nov and 09-Nov.
 Best Quiet Periods: 17-20 Oct, 25-31 Oct, 06-07 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.
