                          Oct, a weak (8nT) impulse was observed 
                          at 1240UT.

*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 International Center for Space Weather 
Science and Education, Japan.


Quiet to unsettled conditions.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 1-20 Nov,  24-30 Nov.

Central Australian Regions:
 Moderately Disturbed Periods: 21-23 Nov
 Best Quiet Periods: 1-20 Nov,  24-30 Nov.

 Disturbed Periods: 21-23 Nov
 Best Quiet Periods: 1-20 Nov,  24-30 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.
