SUBJ: IPS WEEKLY GEOPHYSICAL REPORT 
ISSUED ON 11 AUGUST 2011, BY IPS RADIO AND SPACE SERVICES,
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

1. SUMMARY (02 AUGUST - 10 AUGUST)
K indices are in UT (0-24). For conversion to local time:
AEST = UT + 10 hours; ACST = UT + 9.5 hours; AWST = UT + 8 hours
        Australian Region*

magnetometer data at 2155UT on 04 Aug.
 05 Aug   2111 0255   14    A weak (22nT) impulse was observed in the IPS
magnetometer data at 1902UT on 05 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 5 August, quiet to active from 6 to 9 August, 
otherwise mostly quiet.

2. FORECAST (11 AUGUST - 10 SEPTEMBER)
Disturbed Periods: 
active on 16 Aug, active on 1 and 2 Sep.

Best Quiet Periods: 
 12 Aug to 13 Aug,   20 Aug,  22 Aug to 25 Aug,  29 Aug to 31 Aug,   3 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Southern Australian Regions:
 Disturbed Periods: 16 Aug to 17 Aug.
 Best Quiet Periods: 11 Aug to 14 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.
