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.
27 Oct 3112 1222 6
28 Oct 2433 3212 12 In the BOM magnetometer data for 28
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.
