Mostly quiet to unsettled conditions. Isolated active periods observed
late in week, in association with coronal hole wind stream.

2. FORECAST (18 JANUARY - 17 FEBRUARY)
Disturbed Periods: 
active on 18 Jan, active 29 Jan to 31 Jan, active 12 Feb to 13 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 18 Jan to 11 Feb.

Central Australian Regions:
 Disturbed Periods: 18 Jan to 19 Jan,  12 Feb to 13 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.
