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 24 Nov 2025 23:30 UT)
Date Ap Conditions 25 Nov 20 G0-G1 26 Nov 20 G0-G1 27 Nov 12 G0 chance G1 COMMENT: G0 geomagnetic conditions were mostly observed across the Australian region for UT day 24-Nov, with periods of G1 seen in Alice Springs, Gingin, Learmonth, and Townsville. Periods of G1-G2 geomagnetic conditions were observed in the Antarctic region. G0-G1 geomagnetic conditions are expected on 25-26 Nov, due to high speed wind stream effects from the northern coronal hole. These conditions are expected to decline on 27-Nov, as this coronal hole moves further towards the western solar limb.
