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 27 Jun 6 Quiet 28 Jun 6 Quiet 29 Jun 12 Unsettled COMMENT: Quiet top Unsettled conditions observed over the last 24 hours. Mostly Quiet conditions are expected for 27Jun-28Jun. Unsettled conditions expected on 29Jun due to the influence of a small equatorially located positive polarity coronal hole.
