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 7 days.
Mostly Quiet conditions expected for the forecast period.
2. FORECAST (04 MARCH - 03 APRIL)
No strong recurrent patterns, however mild activity may be experienced on:
Best Quiet Periods:
4 Mar to 14 Mar, 16 Mar to 30 Mar.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: Quiet
Central Australian Regions: Quiet
Southern Australian Regions: Quiet
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
Geomagnetic activity can frequently be determined by short timescale
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
