SUMMARY FOR 07 JUNE AND FORECAST FOR 08 JUNE - 10 JUNE
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 07 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Jun:  66/0

1B. SOLAR FORECAST
             08 Jun             09 Jun             10 Jun
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    68/2               68/2               68/2

COMMENT: The solar wind ranged from 420 to 530 km/s over the 
UT day and is presently 460 km/s. The Bz component IMF started 
the UT day northward, however at around 0530 UT it turned southward 
and maintained this orientation for most of the UT day, reaching 
-7nT at one point. The solar disk remains spotless.

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.

Date      Ap    Conditions
08 Jun     6    Quiet 
09 Jun     4    Quiet 
10 Jun     4    Quiet 

COMMENT: There was some unsettled conditions due to a southward 
orientation of the Bz component of the IMF, leading to reconnection 
with the Earth's magnetic field.
