*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.

22-30 Sep: Quiet to unsettled conditions.


2. FORECAST (01 OCTOBER - 31 OCTOBER)

Geomagnetic conditions may reach active levels during 2-3 Oct 
due to the arrival of the transition region between slow and 
fast solar wind. 

Disturbed Periods: 
2-3 Oct, 12 Oct,  17 Oct,  20 Oct.

Best Quiet Periods: 
1 Oct,  4 Oct,  6 Oct,  8 Oct,  23-26 Oct.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.

Central Australian Regions:
 Disturbed Periods: 4 Oct, 8-9 Oct, 17-19 Oct.

Southern Australian Regions:
 Disturbed Periods: 2-3 Oct, 4 Oct, 8-9 Oct, 17-19 Oct.

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.
