SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 04/2330Z AUGUST 2006 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:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 04 Aug: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Aug: 70/5
1B. SOLAR FORECAST
05 Aug 06 Aug 07 Aug
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 70/5 70/5 70/5
COMMENT: Solar wind is presently 400 km/s. The interplanetary
Bz component has been mostly northward. A weak coronal hole will
enter into a geoeffective position in 2 days time.
-----------------------------------------------------------
2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 04 Aug: Quiet
Estimated Indices 04 Aug : A K
Australian Region 1 11101001
Darwin 1 11100001
Learmonth 0 11000000
Culgoora 1 11100000
Camden 4 11111212
Canberra 1 01002000
Hobart 0 01000000
Casey(Ant) 5 22221121
Observed Regional daily pc3 Indices 04 Aug :
Charters_Towers 0 (Quiet)
Alice_Springs 0 (Quiet)
Culgoora 11 (Quiet)
Canberra 35 (Quiet to unsettled)
Hobart 2 (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
Fredericksburg 3
Planetary 5
Observed AFr/Ap Indices 03 Aug : A K
Fredericksburg 5
Planetary 6 3201 0122
2B. MAGNETIC FORECAST
Date Ap Conditions
05 Aug 6 Quiet
06 Aug 6 Quiet
07 Aug 10 Quiet to Unsettled
COMMENT: Expect geomagnetic activity to remain quiet today and
tomorrow. In two days time the earth will enter a high speed
solar wind stream due to a weak coronal hole. This may cause
the geomagnetic field to reach active levels with a possibility
of isolated minor storms at high latitudes. Expect low and mid
latituds to remain at quiet to unsettled levels.

Date Low Middle High
05 Aug Normal Normal Normal
06 Aug Normal Normal Normal
07 Aug Normal Normal Normal-Fair
COMMENT: Noted isolated cases of sporadic E, otherwise normal
Hf conditions prevail.

COMMENT: Expect normal condition to prevail in the Australian
region, except for isolated cases of sporadic E.
