Quiet to unsettled conditions.

2. FORECAST (05 MARCH - 04 APRIL)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 6-7 Mar,  16-17 Mar,  19 Mar,   31 Mar-01 Apr

 9-15 Mar, 20-26 Mar,  28-30 Mar

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
Best Quiet periods:10-29 Mar
Disturbed periods: None

Central Australian Regions:
Best Quiet periods:10-29 Mar
Mildly disturbed periods: 01 Apr.

Southern Australian Regions:

Disturbed periods: 01 Apr.

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.
