cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather

G2 geomagnetic conditions were observed in the Australian 
region on 04-Aug. Planetary conditions briefly reached G3. 
The brief geomagnetic storm activity was associated with a 
sustained period of southward interplanetary magnetic field 
conditions A G1 period was observed on 30-Jul due to a weak
CME arrival. G0 conditions were observed on other days.

2. FORECAST (08 AUGUST - 07 SEPTEMBER)
Disturbed Periods: 
10-Aug (CME arrival), 27-Aug (weak)


Best Quiet Periods:
8-Aug, 13-17 Aug,  19-20 Aug,  24-25 Aug,  2-3 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
Disturbed periods: none.

Central Australian Regions: 
Disturbed periods: 10-Aug.

Southern Australian Regions: 
Disturbed periods: 10-Aug, 22-Aug, 27-Aug.
Best Quiet Periods: 13-20 Aug and 24-25 Aug.


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.
