SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 06/2330Z JUNE 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 06 JUNE AND FORECAST FOR 07 JUNE - 09 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 06 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 06 Jun: 69/3
1B. SOLAR FORECAST
07 Jun 08 Jun 09 Jun
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 69/3 69/3 69/3
COMMENT: Solar activity was very low over the last 24 hours.
Solar wind speed gradually decreased from 340 to 300 km/s
during the UT day today. The Bz component of the interplanetary
magnetic field fluctuated between +/-4nT almost the whole day
today. Solar activity is expected to stay at very low levels
for the next 3 days.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 06 Jun: Quiet
Estimated Indices 06 Jun : A K

Observed Regional daily pc3 Indices 06 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (Quiet)
Camden 4 (Quiet)
Gnangara 0 (Quiet)
Canberra 0 (Quiet)
Hobart 0 (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 Space Environment Research Center, Japan.
