 04 Aug   5336 4454   35    A weak (49nT) impulse was observed in the IPS
                            magnetometer data at 1020UT on 04 Aug.

*estimated from real time data

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and Space Environment Research Center, Japan.


Minor storm on 4 Aug.
Quiet to unsettled on other days.

2. FORECAST (05 AUGUST - 04 SEPTEMBER)
Disturbed Periods: 
Minor storm on 5 Aug. 
Active on 23 Aug.

Best Quiet Periods: 
 8 Aug to 9 Aug,  12 Aug to 18 Aug,  20 Aug to 22 Aug,  25 Aug to 29 Aug,  
31 Aug.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: 5 to 6 Aug.
 Best Quiet Periods: 8 Aug to 30 Aug.

Central Australian Regions:
 Disturbed Periods: 5 to 6 Aug.
 Best Quiet Periods: 8 Aug to 30 Aug.

Southern Australian Regions:
 Disturbed Periods: 5 to 6 Aug.
 Best Quiet Periods: 8 Aug to 21 Aug,  27 Aug to 30 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.
