SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 01/2330Z AUGUST 2007 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 01 AUGUST AND FORECAST FOR 02 AUGUST - 04 AUGUST
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 01 Aug:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 01 Aug:  68/2


1B. SOLAR FORECAST
             02 Aug             03 Aug             04 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 speed has increased to approximately 610km/s 
as expected due to small coronal hole and is expected to begin 
to decrease midway through the UT day. The Bz component of the 
interplanetary magnetic field fluctuated between +/- 6 nT over 
the last 24 hours with neither the southward or northward orientation 
dominating.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 01 Aug: Unsettled to active

Observed Regional daily pc3 Indices 01 Aug : 
      Darwin               0   (Quiet)
      Townsville           2   (Quiet)
      Learmonth            0   (Quiet)
      Camden              32   (Quiet to unsettled)
      Canberra            29   (Quiet to unsettled)
      Hobart              63   (Active)
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 Space Environment Research Center, Japan.

COMMENT: Coronal hole effects on the geomagnetic field should 
slowly dissipate during the UT day.
