SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 11/2330Z JUNE 2007 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 11 JUNE AND FORECAST FOR 12 JUNE - 14 JUNE
STATUS INDICATORS SOL:GREEN   MAG:** YELLOW **     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 11 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 11 Jun:  73/9


1B. SOLAR FORECAST
             12 Jun             13 Jun             14 Jun
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    75/13              75/13              70/5

COMMENT: The Solar wind has returned to approximately 320 km/s. 
The Bz component of the interplanetary magnetic field fluctuated 
between +/-1 nT over the last 24 hours. AR960 no longer has a 
complex magnetic field and it would be expected that the solar 
flare activity from this region will continue to be very low 
until it rotates onto the the far-side of the sun.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 11 Jun: Quiet

Observed Regional daily pc3 Indices 11 Jun : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)

      Canberra             6   (Quiet)
      Hobart              22   (Quiet to unsettled)
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.

Date      Ap    Conditions
12 Jun     6    Quiet 
13 Jun     6    Quiet 
14 Jun    18    active 

COMMENT: On the 14th of June expect the geomagnetic field to 
range from unsettled to minor storm levels due to the solar wind 
effects of a recurring coranal hole.
