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. 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.

Date Ap Conditions 01 Mar 10 Mostly quiet to unsettled, isolated active periods possible 02 Mar 10 Mostly quiet to unsettled, isolated active periods possible 03 Mar 8 Quiet to Unsettled COMMENT: Quiet to unsettled geomagnetic conditions in Australian region and quite to active conditions at high southern hemisphere latitudes were observed on UT day, 29 February. Global geomagnetic activity is expected to be mostly quiet to unsettled with the possibility of isolated active periods for the next two UT days, 01 to 02 March and then decline to quiet to unsettled levels through UT day, 03 March.
