2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 01 Jun: Quiet
Estimated Indices 01 Jun : A K
Australian Region 4 02121211
Darwin 5 12121212
Townsville 6 1213221-
Learmonth 5 1212221-
Norfolk Island 4 03021111
Camden 3 01121201
Canberra 1 00020101

Estimated Antarctic Regional K Indices 01 Jun :
Macquarie Island 0 00000000
Casey 3 12122010
Mawson 7 33122210
Observed Regional daily pc3 Indices 01 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice Springs 0 (Quiet)
Gnangara 25 (Quiet to unsettled)
Canberra 7 (Quiet)
Hobart 9 (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 01 Jun : A
Fredericksburg 5
Planetary 6
Observed AFr/Ap Indices 31 May : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
02 Jun 4 Quiet
03 Jun 10 Initially Quiet with isolated Unsettled to Active
levels possible later in UT day.
04 Jun 15 Mostly Quiet to Unsettled with the chance of
isolated Active levels.
COMMENT: Isolated Unsettled to Active levels are possible during
3-4 June with the anticipated arrival of a coronal hole solar
wind stream.
