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 08 Apr 8 Quiet to Unsettled 09 Apr 8 Quiet to Unsettled 10 Apr 8 Quiet to Unsettled COMMENT: Quiet geomagnetic conditions were observed for the Australian region on UT day 07 Apr. Global geomagnetic activity is expected to be mostly at Quiet levels for the next three days, 08-10 Apr and a times may reach Unsettled levels due to weak coronal hole effects.
