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 Jun 2022 23:30 UT)

Date Ap Conditions 25 Jun 13 G0 26 Jun 13 G0 27 Jun 8 G0 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 24-Jun. G0 conditions were generally observed in the Antarctic region, with periods of G1 observed at Mawson. G0 conditions are expected over 25-27 Jun in the Australian region, with mild disturbances of the geomagnetic field expected due to coronal hole wind stream effects.
