Quiet to unsettled conditions.

2. FORECAST (27 JANUARY - 26 FEBRUARY)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 27 Jan,  29-30 Jan,  4 Feb,  10-12 Feb,  14 Feb,  18 Feb,  21 Feb.

Best Quiet Periods: 
 28 Jan,  31 Jan to 3 Feb,  5-9 Feb,  13 Feb,  15-17 Feb,  19-20 Feb,  22 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Quiet on all days

Central Australian Regions:
 Moderately Disturbed Periods: 12 - 15 Feb.
 Best Quiet Periods: 27 Jan to 11 Feb, 16-26 Feb.

Southern Australian Regions:
 Disturbed Periods: 12 - 15 Feb.
 Best Quiet Periods: 27 Jan to 11 Feb, 16-26 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.
