                          Jun, a weak (14nT) impulse was observed 
                          at 0435UT.

*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 International Center for Space Weather 
Science and Education, Japan.


Mostly G0 conditions. A mild disturbance was observed
on 15 June with G1 conditions briefly observed at Learmonth, WA.
Below G1 conditions observed at other sites on 15 June.

2. FORECAST (16 JUNE - 16 JULY)
Disturbed Periods: No disturbed days above G1.
Mildly disturbed conditions possible during 16-19, and 24-25 Jun, 12-13 Jul.

Best Quiet Periods: 
20-21Jun,  28 Jun to 2 Jul,  5-8 Jul.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
 Disturbed Periods: None

Central Australian Regions: 
 Disturbed: None
 Mildly Disturbed Periods: 16-19 and 24-27 Jun.
 Best Quiet Periods: 28 Jun-11 Jul.

Southern Australian Regions:
 Disturbed Periods: 16-19 and 24-27 Jun.
 Best Quiet Periods: 28 Jun-11 Jul.


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.
