FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 07 OCTOBER AND FORECAST FOR 08 OCTOBER - 10 OCTOBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 07 Oct:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Oct:  94/40


1B. SOLAR FORECAST
             08 Oct             09 Oct             10 Oct
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    95/41              95/41              95/41
COMMENT: The solar activity was very low over the last 
24 hours. No significant activity was recorded. The solar 
wind speed gradually decreased from 300km/s to 275km/s 
(approx.) by 1900 UT and then increased to 285 km/s by the 
time of this report. The north south component of the 
interplanetary magnetic field (Bz) showed minor fluctuations 
on both sides of the normal value throughout the UT day. 
The solar activity is expected to remain at very low 
levels during 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.
