G0 conditions all week. A coronal hole wind stream mildly increased
geomagnetic activity toward the end of the week. This coronal hole
is broad and is expected to induce a mild increase in geomagnetic
activity over 17-20 Jan.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 16 Jan to 15 Feb.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 21-30 Jan, 04-Feb to 10-Feb.

Southern Australian Regions:

 Best Quiet Periods: 22-29 Jan, 05-Feb to 08-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.
