SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 04/2330Z AUGUST 2005 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 04 AUGUST AND FORECAST FOR 05 AUGUST - 07 AUGUST
STATUS INDICATORS SOL:** YELLOW ** MAG:** YELLOW ** ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 04 Aug: Low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Aug: 106/55
1B. SOLAR FORECAST
05 Aug 06 Aug 07 Aug
Activity Low to moderate Low to moderate Low to moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 105/54 105/54 100/48
COMMENT: Solar regions 794 and 792 both have flare potential.
ACE solar wind data may indicate a coronal hole wind stream entry
late in the UT day. Solar wind speeds is expected to increase
over next few days. A C8 flare was observed at 0559UT and was
associated with a eastward directed mass ejection, which is considered
not to be geoeffective.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 04 Aug: Quiet to Unsettled
Estimated Indices 04 Aug : A K
Australian Region 8 2233 2212
Learmonth 8 3232 2112
Culgoora 8 2233 2112
Canberra 8 2233 2202

Casey(Ant) 11 3333 2212
Observed Regional daily pc3 Indices 04 Aug :
Townsville NA
Learmonth NA
Culgoora NA
Canberra NA
Hobart 11 (Quiet)
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.
Estimated AFr/Ap Indices 04 Aug : A
