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 13 Feb 2025 23:30 UT)

Date Ap Conditions 14 Feb 20 G0-G1 15 Feb 14 G0, chance of G1 16 Feb 12 G0 COMMENT: ASWFC Geomagnetic Warning 9 was issued on 12 February and is current for 14 Feb only. G0 geomagnetic conditions were observed in the Australian region on UT day 13-Feb. G1-G3 conditions was observed in the Antarctic region. G0-G1 geomagnetic conditions are expected on 14-Feb due to coronal hole high speed wind stream effects from a coronal hole in the southern hemisphere. G0 conditions are expected on 15-Feb, with a chance of G1. G0 conditions are expected on 16-Feb.
