                          Nov, a weak (14nT) impulse was observed 
                          at 0514UT.

cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather

Quiet to unsettled conditions.

2. FORECAST (29 NOVEMBER - 29 DECEMBER)
Disturbed Periods: 
 30 Nov to 1 Dec.

Best Quiet Periods: 
 8-15 Dec, 19-27 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed periods: none
Best Quiet periods: 03 Dec to 27 Dec.

Central Australian Regions:
Mildly Disturbed periods: 30 Nov to 1 Dec.
Best Quiet periods: 03 Dec to 27 Dec.

Southern Australian Regions:
Disturbed periods: 30 Nov to 1 Dec.
Best Quiet periods: 08-15 Dec,19-27 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.
