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.
Mostly quiet to unsettled conditions. Active periods observed on 30 July.
2. FORECAST (04 AUGUST - 03 SEPTEMBER)
Unsettled on 4 Aug, active on 5 Aug, unsettled on 6 Aug, active on 16 Aug.
Best Quiet Periods:
11 Aug to 13 Aug, 20 Aug, 22 Aug to 25 Aug, 29 Aug to 30 Aug.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Southern Australian Regions:
Disturbed Periods: 16 Aug to 17 Aug.
Best Quiet Periods: 4 Aug to 5 Aug, 10 Aug to 14 Aug.
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.
