SUMMARY FOR 05 AUGUST AND FORECAST FOR 06 AUGUST - 08 AUGUST
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 05 Aug:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 05 Aug:  70/5

1B. SOLAR FORECAST
             06 Aug             07 Aug             08 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 370 km/s. The interplanetary 
Bz component was southward up to -4nT earily on 05 Aug UT day, 
causing some unsettled levels in the geomagnetic field at high 
latitudes. Later in the UT day it return to fluctuating between 
-/+ 2nT. A weak coronal hole will enter into a geoeffective position 
tomorrow and may cause some active to unsettled levels at high 
latitudes.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 05 Aug: Quiet

Observed Regional daily pc3 Indices 05 Aug : 
      Charters_Towers      0   (Quiet)
      Alice_Springs        0   (Quiet)
      Culgoora             2   (Quiet)
      Canberra            23   (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 05 Aug : A

           Planetary              5                         

Observed AFr/Ap Indices 04 Aug :  A   K

2B. MAGNETIC FORECAST 
Date      Ap    Conditions
06 Aug     6    Quiet 
07 Aug    10    Quiet to Unsettled 
08 Aug    10    Quiet to Unsettled 

COMMENT: Expect geomagnetic activity to remain quiet today. Tomorrow 
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 at high latitudes. Expect low and mid latituds 
to remain at quiet to unsettled levels.
