SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 14/2330Z MAY 2004 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 14 MAY AND FORECAST FOR 15 MAY - 17 MAY
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 14 May:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 14 May: 110/60


1B. SOLAR FORECAST
             15 May             16 May             17 May
Activity     Low                Low                Low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   112/63             115/66             115/66
COMMENT: Solar activity was low over the past 24 hours. Only 
a few B class flares from region 609, the largest being a B7 
at 0730UT and a B5 at 2100UT. Region 609 grew slightly over the 
past 24 hours and is expected to be the source of further C-class 
and possible M-class flares. The solar wind speed declined from 
440km/s at 0000UT to 350km/s at the end of the UT day. The interplanetary 
magnetic field, Bz was north for most of the UT day untill 1945UT 
where it went southward at a maximum of -8nT and has remained 
at this level up to the time of this report.

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.
