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 24 Jan 2022 23:31 UT)

Date Ap Conditions 25 Jan 11 Quiet to Active 26 Jan 10 Quiet to Active 27 Jan 8 Quiet to Unsettled COMMENT: Geomagnetic conditions in the Australian region were quiet on UT day 24 January. Quiet to minor storm levels were observed in Antarctica. Quiet to unsettled conditions are expected 25-27 January. Isolated active periods are possible on 25-26 January due to coronal hole effects and a possible mild coronal mass ejection impact. Mostly quiet conditions are expected on 27 January.
