                          Jan, a weak (16nT) impulse was observed 
                          at 0536UT and a weak (10nT) impulse 
                          was observed at 1509UT.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None
 Best Quiet Periods: 11-14 Jan, 17-Jan to 10-Feb.

Central Australian Regions: 
 Disturbed Periods: None
 Best Quiet Periods: 11-14 Jan, 17-Jan to 10-Feb.

Southern Australian Regions:

 Best Quiet Periods: 11-13 Jan, 18-27 Jan, 4-11 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.
