SUBJ: IPS WEEKLY GEOPHYSICAL REPORT
ISSUED ON 18 MARCH 2010, BY IPS RADIO AND SPACE SERVICES,
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
1. SUMMARY (09 MARCH - 17 MARCH)
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

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.
2. FORECAST (18 MARCH - 17 APRIL)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
18 Mar, 7 Apr to 8 Apr.
Best Quiet Periods:
19 Mar to 6 Apr, 9 Apr to 13 Apr.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: Quiet
Central Australian Regions: Quiet
Southern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 18 Mar to 24 Mar.
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.
