1. SUMMARY (05 NOVEMBER - 13 NOVEMBER)
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

                          Nov, a weak (15nT) impulse was observed 
                          at 1515UT.

*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.

Generally G0 conditions observed this week. A weak CME arrival 
was observed on 07-Nov but no significant geomagnetic activity 
followed the impulse. A G1 period was briefly observed on 09-Nov. 
A mild increase in geomagnetic activity was observed over 09-10 Nov 
in association with southward interplanetary magnetic field conditions.

2. FORECAST (14 NOVEMBER - 14 DECEMBER)
Disturbed Periods: 
14-15 Nov,  7 Dec.

Best Quiet Periods: 
 17-21 Nov,  27-28 Nov, 9-10 Dec, 13-14 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 14 Nov to 10 Dec.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 17-22 Nov, 5-10 Dec.

Southern Australian Regions:
 Disturbed Periods: 14-16 Nov,  11-13 Dec.
 Best Quiet Periods:  17-22 Nov,  5-10 Dec.


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.
