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

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 01 Aug:  83/24


1B. SOLAR FORECAST
             02 Aug             03 Aug             04 Aug
Activity     Low                Low                Low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    80/20              85/27              85/27
COMMENT: ACE solar wind data shows a weak shock-like discontinuity 
at around 0149UT. Solar wind speed jumped from 482 to 532km/sec 
then declined and is currently at 430km/sec. This minor event was 
probably a glancing blow from the slow decline C8/CME event at 0657UT 
on 31 July. No significant flare activity has been observed over 
the past 24 hours.

of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.
