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 12 Jun 2026 23:47 UT)
Date Ap Conditions 13 Jun 30 G1-G2 14 Jun 16 G0, chance of G1 15 Jun 8 G0 COMMENT: ASWFC Geomagnetic Warning 37 was issued on 11 June and is current for 12-14 Jun. G0 geomagnetic conditions were observed on UT day 12-Jun in the Australian region and at the planetary level. Mostly G2 geomagnetic conditions were observed in the Antarctic region. G1-G2 geomagnetic conditions are expected on 13-Jun due to ongoing coronal hole high speed wind stream effects and an anticipated glancing impact from a CME first observed on 11-Jun. Conditions are expected to ease over 14-15 Jun with a chance of G1 on 14-Jun and G0 conditions expected on 15-Jun.
