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 Jul 2025 23:32 UT)
Date Ap Conditions 09 Jul 16 G0, chance G1 10 Jul 12 G0 11 Jul 10 G0 COMMENT: ASWFC Geomagnetic Warning 52 was issued on 7 July and is current for 8-9 Jul. G0 geomagnetic conditions were observed in the Australian region on UT day 8-Jul. G0-G2 geomagnetic conditions were observed in the Antarctic region. Geomagnetic 27 day recurrence patterns indicating that G1 conditions are likely during the interval 8-9 Jul have so far failed to eventuate. There is a chance of a very weak glancing blow arrival from late in the UT day 10-Jul to early in the UT day 11-Jul from a north directed CME associated with a recent erupting solar filament.
