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 10 Jun 2025 23:30 UT)

Date Ap Conditions 11 Jun 14 G0, chance G1 12 Jun 14 G0, chance G1 13 Jun 10 G0 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 10-Jun. Mostly G0 geomagnetic conditions were observed in the Antarctic region, with a period of G1 conditions observed at Mawson. G0 geomagnetic conditions are generally expected over 11-12 Jun, with a chance of G1 conditions on 11-12 Jun due to anticipated high speed wind stream effects from a small equatorial coronal hole.
