Antarctic Division and Space Environment Research Center, Japan.


active on 24 Jan.
quiet to unsettled on other days.

2. FORECAST (02 FEBRUARY - 03 MARCH)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
  4 Feb,   12 Feb,  18 Feb to 21 Feb.

Best Quiet Periods: 
 2 Feb to 3 Feb,  5 Feb to 11 Feb,  13 Feb to 17 Feb,  22 Feb to 28 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 2 Feb to 28 Feb.

Central Australian Regions:
 Mildly Disturbed Periods: 21-23 Feb 
 Best Quiet Periods: 2 Feb to 19 Feb,  25 Feb to 28 Feb.

Southern Australian Regions:
 Disturbed Periods: 21-23 Feb
 Best Quiet Periods: 2 Feb to 19 Feb,  25 Feb to 28 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.
