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 20 Nov 2024 23:31 UT)

Date Ap Conditions 21 Nov 8 G0 22 Nov 15 G0, slight chance of G1 23 Nov 14 G0, slight chance of G1 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 20-Nov. Mostly G0 geomagnetic conditions were observed in the Antarctic region, with an isolated period of G1 observed at Casey. G0 geomagnetic conditions are expected over 21-23 Nov, with a slight chance of G1 over 22-23 Nov due to coronal hole high speed wind stream effects.
