Observed Regional daily pc3 Indices 23 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)

Pc3 pulsations are high frequency (10-45 second period) variations
of the Earths magnetic field. 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 Space Environment Research Center, Japan.

for Equatorial regions ranging from 10%-20% for the next 3 days.
Depressed conditions during local day expected for Northen AUS
and Southern AUS/NZ regions over the next 3 days with continued
disturbed conditions for Antarctic regions.
