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 Aug 2026 23:47 UT)
Date Ap Conditions 09 Aug 15 G1, chance of G2 10 Aug 7 G0 11 Aug 12 G0, chance of G1 COMMENT: ASWFC Geomagnetic Warning 50 was issued on 8 August and is current for 8-9 Aug. G1 geomagnetic conditions were observed on 08-Aug in the Australian region. G2 geomagnetic conditions were observed at the planetary level and mostly G3 conditions were observed in the Antarctic region. G1 geomagnetic activity is expected on 09-Aug, with a chance of G2. The strongest geomagnetic activity is expected in the first half of the UT day. G0 conditions are expected over 10-11 Aug, with a chance of G1 on 11-Aug due to a combination of potential coronal hole high speed wind stream effects and a possible glancing CME impact.
