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 29 Apr 2025 23:31 UT)

Date Ap Conditions 30 Apr 9 G0 01 May 15 G0, chance G1 02 May 15 G0, chance G1 COMMENT: G0 geomagnetic conditions were observed in the Australian and Antarctic regions on UT day 29-Apr. G0 geomagnetic conditions are generally expected over 30-Apr to 02-May, with a mild increase in geomagnetic activity during 01-02 May due to a coronal hole wind stream.
