SUMMARY FOR 05 JUNE AND FORECAST FOR 06 JUNE - 08 JUNE
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 05 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 05 Jun:  72/8

1B. SOLAR FORECAST
             06 Jun             07 Jun             08 Jun
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    70/5               70/5               70/5

COMMENT: The solar wind speed ranged from around 540 to 450 km/s 
and is currently about 470 km/s. The north-south component of 
the IMF varied between about +/-4 nT. LASCO and STEREO A imagery 
show a CME event at around 1156 UT on 5 June which does not appear 
to be Earth directed. Solar wind parameters are expected to become 
disturbed on day two due to the effects of a recurrent coronal 
hole.

      Townsville           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.
