*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 to unsettled conditions.

2. FORECAST (28 JANUARY - 27 FEBRUARY)
Disturbed Periods: 16 February

Best Quiet Periods: 28 January to 15 February, 17 to 27 February

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 28 Jan to 27 Feb.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 28 Jan to 27 Feb.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 28 Jan to 27 Feb.

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.
