FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 01 OCTOBER AND FORECAST FOR 02 OCTOBER - 04 OCTOBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 01 Oct:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 01 Oct:  88/32


1B. SOLAR FORECAST
             02 Oct             03 Oct             04 Oct
Activity     Very low           Very low           Low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    90/34              95/41              95/41
COMMENT: Solar activity was very low over the last 24 hrs. The 
solar wind velocity continued to fall from 360km/s at 0000UT 
to 340km/s at the time of this report. The north south component 
of the interplanetary magnetic field (Bz) fluctuated between 
4nT and -2nT throughout the UT day. These conditions are expected 
to continue for the next two days with no observed growth or 
increase in magnetic complexity of any of the current solar regions 
on disc.

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.
