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: 104/53


1B. SOLAR FORECAST
             06 Aug             07 Aug             08 Aug
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   105/54             105/54             110/60

COMMENT: Very Low solar activity over the last 24hours. Solar 
wind speed ranged between 550-600km/s for the first half of the 
UT day before declining to be ~500km/s at the time of this report. 
Bz was -10nT at 00UT after which it fluctuated between 0 and 
-5nT over the rest of the UT day. Very Low to Low solar activity 
is expected for the next few days (possible C-class events) with 
no significant active regions currently on disk.

      Davis               29   43323654

Observed Regional daily pc3 Indices 05 Aug : 
      Darwin              12   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Alice Springs        0   (Quiet)
      Gingin               6   (Quiet)
      Canberra             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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather 
Science and Education, Japan.

06 Aug     9    Quiet to Unsettled
07 Aug     5    Quiet

COMMENT: Quiet to Active conditions observed over the last 24 
hours due to coronal hole effects. Solar wind speed is expected 
to decline over the next 3 days with Quiet to Unsettled conditions 
expected for 06Aug with possible Active periods for high latitudes. 
Mostly Quiet conditions expected for 07Aug-08Aug.
