FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 OCTOBER AND FORECAST FOR 09 OCTOBER - 11 OCTOBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 08 Oct:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Oct: 171/125

1B. SOLAR FORECAST
             09 Oct             10 Oct             11 Oct
Activity     Low                Low                Low
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   165/119            170/124            170/124

COMMENT: Solar activity is expected to be low. 
ACE EPAM data indicates an energetic ion enhancement event beginning 
08/0815UT, which can be a precursor to increased geomagnetic 
activity over next 24-36 hours.

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.
