Observed Regional daily pc3 Indices 03 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (Quiet)
Culgoora 9 (Quiet)
Camden 12 (Quiet)

Canberra 8 (Quiet)
Hobart 13 (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 03 Jun : A
Fredericksburg 5
Planetary 5

2B. MAGNETIC FORECAST
Date Ap Conditions
04 Jun 5 Quiet
05 Jun 5 Quiet
06 Jun 7 Quiet
COMMENT: Activity occurred in the last six hours at the high
latitude stations, Davis and Mawson. The geomagnetic field may
become unsettled late on the 6 June due to a coronal hole wind
stream.
