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 16 Jan 2026 23:30 UT)
Date Ap Conditions 17 Jan 15 G0-G1 18 Jan 24 G1, chance of G2 19 Jan 24 G1 COMMENT: Geomagnetic conditions in the Australian region were at the G0 level for UT day 16-Jan, with isolated G1 intervals recorded at Learmonth and Gingin. Geomagnetic conditions reached the G1 level at the planetary level, with periods of G3-G4 observed in the Antarctic region. G0-G1 conditions are forecast for 17-Jan, as the effects from a possible solar transient continue. Geomagnetic conditions are likely to increase on 18-Jan to G1, with a chance of G2, as the Earth enters a coronal hole high-speed wind stream. G1 conditions are forecast for 19-Jan as the high-speed wind stream effects persist.
