1. SUMMARY (22 OCTOBER - 30 OCTOBER)
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

 26 Oct   1121 2434   11  In the BOM magnetometer data for 26 
                          Oct, a weak (18nT) impulse was observed 
                          at 1619UT.

                          Oct, a weak (25nT) impulse was observed 
                          at 0447UT.

*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.


G0 conditions were observed during the week. Two CME arrivals were
observed but only a slight increase in geomagnetic activity followed
the geomagnetic impulses on 26-Oct and 28-Oct.

2. FORECAST (31 OCTOBER - 30 NOVEMBER)
Disturbed Periods: 
5-7 Nov.

Best Quiet Periods: 
9-10 Nov,  16-22 Nov

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 31 Oct to 1 Nov,  9-30 Nov.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 31 Oct to 1 Nov,  10-21 Nov.

Southern Australian Regions:
 Disturbed Periods: 7-8 Nov,  24-26 Nov.
 Best Quiet Periods: 31 Oct to 1 Nov,  10-21 Nov.


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.
