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 18 Mar 2024 23:30 UT)

Date Ap Conditions 19 Mar 12 G0, chance G1 20 Mar 12 G0, chance G1 21 Mar 8 G0 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 18-Mar. Mostly G0 geomagnetic conditions were observed in the Antarctic region, with an isolated period of G1 observed at Mawson. G0 geomagnetic conditions are expected over 19-21 Mar, with a chance of G1 on 19-Mar due to ongoing effects from a weak CME arrival and a chance of G1 on 20-Mar due to the expected arrival of a weak CME first observed on 17-Mar.
