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 Jan 2026 23:30 UT)

Date Ap Conditions 30 Jan 12 G0, chance of G1 31 Jan 8 G0 01 Feb 8 G0 COMMENT: G0 geomagnetic conditions were observed in Australia and a brief period of G3 has been observed in Antarctic regions. G0 with chance of G1 geomagnetic conditions are expected over 30-Jan due to high speed wind stream effects from a geoeffective coronal hole. G0 geomagnetic conditions are expected for 31-Jan to 01-Feb.
