FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 05 JUNE AND FORECAST FOR 06 JUNE - 08 JUNE
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 05 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 05 Jun:  71/6


1B. SOLAR FORECAST
             06 Jun             07 Jun             08 Jun
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    72/8               72/8               72/8

COMMENT: Solar activity was very low on UT day 05 June. There 
is currently one numbered sunspot region on the visible disc, 
AR 2765(S23E47) and one plage without spot 2764(N35E03). No Earthward 
directed CMEs were observed in the available coronagraph images. 
Very low levels of solar activity with a slight chance of an 
isolated C-class flare are expected for the next three UT days, 
06-08 June. During UT day 05 June, the solar wind speed varied 
in the range 310-350 km/s. The total IMF (Bt) varied between 
2 nT and 5 nT, and the north-south IMF component (Bz) varied 
mostly in the range -/+3 nT. The solar wind speed is expected 
to be at background to slightly enhanced levels during UT days 
06-08 June due to weak coronal hole effects.

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 conditions in the Australian region were 
quiet on UT day 05 June. The Antarctic region observed mostly 
quiet levels, with one isolated unsettled to active period. Global 
geomagnetic activity is expected to be mostly quiet with a chance 
of isolated unsettled periods for UT days 06-08 June.

near predicted monthly values to slightly enhanced. Sporadic 
E was observed over some sites. MUFs in the Australian region 
are expected to be mostly near predicted monthly values for the 
next three UT days, 06-08 June.
