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 Apr 2026 23:30 UT)
Date Ap Conditions 09 Apr 14 G0-G1 10 Apr 20 G0-G1 11 Apr 18 G0, chance of G1 COMMENT: ASWFC Geomagnetic Warning 26 was issued on 7 April and is current for 9-10 Apr. Geomagnetic conditions in the Australian region were at the G0 level on UT day 08-Apr, with G0 conditions also reported at the planetary level. Periods of G1-G2 geomagnetic conditions were recorded in the Antarctic region. G0-G1 conditions are forecast for 09-Apr, with two equatorial coronal holes likely to move into a geoeffective position late in the UT day. G0-G1 conditions are forecast for 10-Apr due to the high-speed wind stream effects of these coronal holes. This will decrease to G0, with a chance of G1 on 11-Apr.
