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 14 Nov 2025 23:42 UT)

Date Ap Conditions 15 Nov 8 G0 16 Nov 25 G1, chance of G2 17 Nov 10 G0 COMMENT: G0 geomagnetic conditions were observed across the Australian and Antarctic regions over UT day 14-Nov. G0 geomagnetic conditions are expected on 15-Nov. G1 conditions, with a chance of G2 are expected on 16-Nov due to two anticipated glancing CME impacts combined with a coronal hole high speed wind stream. G0 conditions are expected on 17-Nov
