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.

2. FORECAST (15 JANUARY - 14 FEBRUARY)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
  19 Jan,   27 Jan,   30 Jan.

Best Quiet Periods: 
 15 Jan to 18 Jan,  20 Jan to 26 Jan,  28 Jan to 29 Jan,  31 Jan to 10 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Southern Australian Regions:
 Disturbed Periods: 19 Jan.
 Best Quiet Periods: 15 Jan to 18 Jan, 31 Jan to 10 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.
