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 08 Jan 2026 23:30 UT)

Date Ap Conditions 09 Jan 30 G1 10 Jan 30 G0-G1 11 Jan 18 G0 chance G1 COMMENT: Geomagnetic conditions in the Australian region were at the G0 level across UT 08-Jan. Periods of G1 geomagnetic activity were observed in the Antarctic region. Conditions are expected to reach G1 on 09-Jan due to the influence of a coronal hole high-speed wind stream and possible effects of a partial CME impact. G0-G1 conditions are forecast for 10-11 Jan as the Earth continues to pass through this coronal hole high-speed wind stream.
