SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 04/2330Z JUNE 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 04 JUNE AND FORECAST FOR 05 JUNE - 07 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 04 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Jun: 71/6
1B. SOLAR FORECAST
05 Jun 06 Jun 07 Jun
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 71/6 71/6 71/6
COMMENT: Solar activity was very low over the last 24 hours.
The solar wind stream did not get strengthened upto the
previously anticipated levels. Solar wind speed stayed mostly
between 300 and 340 km/s during the UT day today. The Bz
component of the interplanetary magnetic field stayed negative
almost the whole day, sometimes upto around -5 nT. Solar
activity is expected to stay at very low levels for the next
3 days.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 04 Jun: Moslty quiet, isolated
unsettled periods.
Estimated Indices 04 Jun : A K

Observed Regional daily pc3 Indices 04 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 2 (Quiet)
Camden 0 (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.
Estimated AFr/Ap Indices 04 Jun : A
Fredericksburg 5

07 Jun 3 Quiet
COMMENT: Geomagnetic activity remained mostly at quiet
levels today with some unsettled periods observed. Activity
level is expected to remain at quiet levels for the next
three days.
