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 23 Nov 14 Quiet to Active 24 Nov 10 Quiet to Unsettled 25 Nov 8 Quiet to Unsettled COMMENT: Quiet to minor storm geomagnetic conditions were observed in the Australian region. Quiet to major storm conditions were observed in the southern high latitude region on UT day 22 November. Quiet to active conditions are expected on 23 Nov due to continuing coronal hole effects.
