1. SUMMARY (12 OCTOBER - 20 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

*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.


Quiet to Unsettled conditions observed over the last week. 
Quiet to Unsettled conditions expected for the next 7 days with
some isolated Active periods for mid to high latitudes on 
21Oct-24Oct due to recurrent coronal hole activity.

2. FORECAST (21 OCTOBER - 20 NOVEMBER)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 21 Oct to 23 Oct,   2 Nov,  7 Nov to 8 Nov,   13 Nov,   16 Nov.

Best Quiet Periods: 
 24 Oct to 1 Nov,  3 Nov to 6 Nov,  9 Nov to 12 Nov,  14 Nov to 15 Nov.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: Quiet 

Central Australian Regions: Quiet 

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 21 Oct to 7 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.
