2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 04 Jun: Quiet
Estimated Indices 04 Jun : A K
Australian Region 3 12111101
Darwin 4 22111111
Townsville 6 22212212

Observed Regional daily pc3 Indices 04 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 2 (Quiet)
Alice_Springs 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.
Estimated AFr/Ap Indices 04 Jun : A
Fredericksburg 3
Planetary 5
Observed AFr/Ap Indices 03 Jun : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
05 Jun 5 Quiet
06 Jun 7 Quiet
07 Jun 12 Unsettled
COMMENT: The geomagnetic field may become unsettled late on the
6 June due to a coronal hole wind stream. This activity is expected
to persist on the 7th.
