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.


Quiet on most days, unsettled to minor storm on 01 March
and unsettled to active on 02 March. 

2. FORECAST (03 MARCH - 02 APRIL)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 3 Mar to 5 Mar,   13 Mar,   17 Mar.

Best Quiet Periods: 
 6 Mar to 12 Mar,  14 Mar to 16 Mar,   18 Mar to 29 Mar, 2 Apr.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 3 Mar to 6 Mar.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 3 Mar to 6 Mar.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 3 Mar to 5 Mar.

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.
