3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 30 May to 5 Jun,  10-25 Jun.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 30 May to 5 Jun,  10-25 Jun.

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:
Two flare active solar regions are currently in the eastern solar 
hemisphere of the Sun. There is an increasing risk of CME induced 
geomagnetic storm activity as these regions move into a move geoeffective 
solar longitude range as the week progresses if these two regions 
produce further CMEs.

Geomagnetic activity can frequently be determined by short timescale 
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
