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 11 Jul 8 G0 12 Jul 14 G0-G1 13 Jul 14 G0, chance of G1 COMMENT: Geomagnetic conditions in the Australian region were at the G0 level on UT day 10-Jul, with G0 conditions also reported at the planetary scale. G1 conditions were recorded in the Antarctic region. G0 geomagnetic conditions are forecast for 11-Jul. This will rise to G0-G1 on 12-Jul, and G0, with chance of G1 on 13-Jul, due to a glancing CME impact forecast to arrive on 12-Jul.
