COMMENT: Solar activity was Very Low for UT day 2 June. There 
are no sunspots on the visible solar disk. There were no earth-directed 
Coronal Mass Ejections (CMEs) observed in the available coronagraph 
imagery. Very Low solar activity is expected for the next 3 UT 
days, 3-5 June. During the UT day 2 June, the solar wind speed 
was near its background levels. The IMF Btotal varied in the 
range 2-5 nT. There were no significant periods of negative Bz. 
On UT day 3 June the solar wind speed is expected to remain near 
its background levels.

Observed Regional daily pc3 Indices 02 Jun : 
      Darwin               0   (Quiet)
      Townsville          NA
      Learmonth            0   (Quiet)

      Melbourne           NA

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 International Center for Space Weather 
Science and Education, Japan.

COMMENT: Geomagnetic activity was at Quiet levels across the 
Australian region for the UT day 2 June. Mostly Quiet levels 
were observed in Antarctica. For the next 3 UT days, 3-5 June, 
the global geomagnetic activity is expected to be mostly at Quiet 
levels.

COMMENT: During the last 24 hours maximum usable frequencies 
(MUFs) were mostly near predicted monthly values and mildly enhanced. 
Mild to moderate depressions were also observed across the mid 
and high latitude regions in the Northern hemisphere. Variable 
HF conditions are expected for 3 June. Occasional enhancements 
are possible across all latitudes. For the Northern hemisphere, 
mildly to moderately depressed MUFs are likely for mid to high 
latitudes. For the Southern hemisphere, near predicted monthly 
MUFs are expected with disturbed ionospheric support for high 
latitudes.

COMMENT: Maximum usable frequencies (MUFs) ranged mostly from 
near predicted monthly values to mildly enhanced ones for Australian 
regions and Antarctica. Sporadic-E occurrences were observed 
over some Australian ionosonde sites. For 3-5 June, MUFs are 
expected to range mostly near predicted monthly levels.
