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

      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.
