ISSUED AT 23/2330Z OCTOBER 2004 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 23 OCTOBER AND FORECAST FOR 24 OCTOBER - 26 OCTOBER
STATUS INDICATORS SOL:** YELLOW **   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 23 Oct:  Low

Flares: None

Observed 10.7 cm flux/Equivalent Sunspot Number for 23 Oct: 130/NA 


1B. SOLAR FORECAST
             24 Oct             25 Oct             26 Oct
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   130/NA             130/NA            130/NA 
COMMENT: Recent CME activity appearing to originate from solar 
rgion 687 does not appear to be Earthward directed and is not 
expected to be geoeffective. Solar region 687 has the chance 
of producing further M-class flare activity. Solar wind speeds 
have been between 340 km/s to 400km/s during 23 October and are 
expected to mostly remain below 400km/s over the next few days.

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.
