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 29 Dec 2024 23:30 UT)

Date Ap Conditions 30 Dec 6 G0 31 Dec 20 G2, chance G3 01 Jan 25 G1-22, chance G3 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 29-Dec. G0-G2 geomagnetic conditions were observed in the Antarctic region. G0 geomagnetic conditions are expected on UT day 30-Dec. By late 31-Dec, a CME arrival is expected to induce G2, with a chance for G3 geomagnetic conditions. This geomagnetic activity is expected to continue into 01-Jan. Two other CME arrivals are possible on 01-Jan, contributing to the enhanced geomagnetic activity.
