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 26 Jan 2020 23:35 UT)

Date Ap Conditions 27 Jan 5 Quiet 28 Jan 10 Quiet with a chance of isolated Unsettled periods 29 Jan 7 Mostly Quiet COMMENT: Geomagnetic activity for 26 January was Quiet for the Australian region. The Antarctic region observed Quiet to Unsettled conditions. Global geomagnetic activity is expected to be mostly at Quiet levels for the next three days, 27-29 January with a chance of isolated Unsettled periods due to weak coronal hole effects.
