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 Jul 2024 23:30 UT)

Date Ap Conditions 27 Jul 16 G0, chance G1 28 Jul 13 G0, slight chance G1 29 Jul 13 G0, slight chance G1 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 26-Jul, with an isolated period of G1 observed at Townsville and Learmonth. The planetary Kp reached G1 during the period 26/03-06UT. Mostly G0 conditions were observed in Antarctica, with isolated periods of G1 and G2 observed at Macquarie Island and Mawson. Mostly G0 geomagnetic conditions are expected over 27-29 Jul, with periods of G1 conditions possible due to weak CME glancing blows.
