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 01 Jul 2020 23:31 UT)

Date Ap Conditions 02 Jul 6 Mostly quiet, isolated unsettled periods possible 03 Jul 6 Mostly quiet, isolated unsettled periods possible 04 Jul 6 Mostly quiet, isolated unsettled periods possible COMMENT: On UT day 01 July, geomagnetic conditions were quiet in the Australian region. Mostly quiet conditions with isolated unsettled periods were observed in the Antarctic region. Global geomagnetic activity is expected to be mostly quiet for the next three UT days, 02 to 04 July, with small possibility of isolated unsettled periods due to week coronal hole effects.
