SUBJ: IPS WEEKLY GEOPHYSICAL REPORT
ISSUED ON 13 NOVEMBER 2008, BY IPS RADIO AND SPACE SERVICES,
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
1. SUMMARY (04 NOVEMBER - 12 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

*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 are expected for this forecast period.
Unsettled conditions possible 14Nov-16Nov due to a high latitude
positioned coronal hole moving into geoeffective position.
2. FORECAST (13 NOVEMBER - 13 DECEMBER)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
15 Nov, 25 Nov to 26 Nov, 4 Dec to 6 Dec.
Best Quiet Periods:
13 Nov to 14 Nov, 16 Nov to 24 Nov, 27 Nov to 3 Dec, 7 Dec to 9 Dec.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 13 Nov to 30 Nov.
Central Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 13 Nov to 24 Nov, 27 Nov to 30 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.
