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 04 Mar 2026 23:30 UT)

Date Ap Conditions 05 Mar 5 G0 06 Mar 5 G0 07 Mar 12 G0, chance of G1 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 04-Mar. Mostly G0 geomagnetic conditions were observed in the Antarctic region, with a period of G1 observed at Casey. G0 geomagnetic conditions are expected on 05-06 Mar. G0 conditions, with a chance of G1 are expected on 07-Mar due to anticipated coronal hole high speed wind stream effects.
