G0 geomagnetic conditions were observed in the Australian region throughout
the previous week. Planetary G2 was reached on 04-May, and planetary G1 
was reached on 05-May. Planetary G0 on other days.

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.
