*estimated from real time data

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 Space Environment Research Center, Japan.

Mostly quiet, unsettled periods 1, 7 and 8 Nov. Isolated active to
minor storm levels on 1 Nov. A weak (15nT) impulse was observed in
the IPS magnetometer data at 0908UT on 01 Nov. 

2. FORECAST (10 NOVEMBER - 10 DECEMBER)
Disturbed Periods: 
active on 11 to 12 Nov, active 20 to 21 Nov and 28 Nov.

Best Quiet Periods: 
 14 to 19 Nov, 22 to 26 Nov and 30 Nov to 10 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 10 Nov to 10 Dec.

Central Australian Regions:
 Mildly Disturbed Periods: 11 to 12 Nov.
 Best Quiet Periods: 14 to 20 Nov, 22 Nov to 10 Dec.

Southern Australian Regions:
 Disturbed Periods: 11 to 12 Nov.
 Best Quiet Periods: 14 to 20 Nov, 22 Nov to 10 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.
