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.

Geomagnetic Forecast
(last updated 06 Apr 2025 23:30 UT)
Date Ap Conditions 07 Apr 8 G0 08 Apr 15 G0, chance G1 late in UT day 09 Apr 20 G1, chance G2 COMMENT: ASWFC Geomagnetic Warning 26 was issued on 6 April and is current for 9-10 Apr. G0 geomagnetic conditions were observed in the Australian region on UT day 06-Apr. In the Antarctic region G3 periods were observed at Mawson and G1-G2 periods were observed at Casey and G1 conditions were observed at Macquarie Island. A single period of G1 planetary geomagnetic conditions was observed early in the UT day. G0 conditions are expected on 07-Apr and are also generally expected on 08-Apr. A 27 day recurrent interplanetary magnetic field pattern of southward IMF Bz conditions suggests an increase in geomagnetic activity to G1, chance G2 conditions for 09-Apr.
