1A. SOLAR SUMMARY
Activity 03 Jun:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 03 Jun: 109/59

COMMENT: Solar activity remained at Low levels during the UT 
day, 3 Jun. All visible regions remained relatively stable and 
not magnetically complex. Solar activity is expected to remain 
at Low levels for the next three days. GONG Learmonth H alpha 
images recorded two filaments lifting off from the Northeast 
limb ~0150UT and the Northwest limb ~ 0716UT are unlikely to 
be geoeffective. No other noteworthy Earthward directed CMEs 
were recorded in the available SOHO/LASCO observations. Solar 
wind conditions are ambient and are expected to remain so for 
the next 3 days.

Observed Regional daily pc3 Indices 03 Jun : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)

      Canberra             0   (Quiet)
      Melbourne            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 International Center for Space Weather 
Science and Education, Japan.
