*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.


Quiet to unsettled conditions observed from 15 to 20 January due 
to the effect of a high speed solar wind stream from a recurrent 
coronal hole.  Quiet conditions have been observed from 21 to 23 
January and are expected to continue at quiet levels for the next 
few days.

2. FORECAST (24 JANUARY - 23 FEBRUARY)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 3, 9, 10 and 12 February.

Best Quiet Periods: 
 24 to 31 January, 5 to 8 February,  15 to 23 February. 

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 24 Jan to 7 Feb,  12 Feb to 14 Feb.

Southern Australian Regions:
 Disturbed Periods: 9 Feb to 10 Feb.
 Best Quiet Periods: 24 Jan to 6 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.
