Quiet to unsettled conditions.

2. FORECAST (10 SEPTEMBER - 10 OCTOBER)

Southern Australian Regions: 
Disturbed condition: 27-29 Sep, otherwise quiet



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.
