SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 01/2330Z JUNE 2008 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 01 JUNE AND FORECAST FOR 02 JUNE - 04 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 01 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 01 Jun: 67/0
1B. SOLAR FORECAST
02 Jun 03 Jun 04 Jun
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 68/2 68/2 68/2
COMMENT: The visible disk is presently spotless. Solar wind speeds
ranged from approximately 540 km/s up to 640 km/s during the
past 24 hours under the influence of a coronal hole wind stream
and are presently approximately 620 km/s. Solar wind speeds are
expected to decline slowly over the next 24-48 hours.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 01 Jun: Quiet to Unsettled
Estimated Indices 01 Jun : A K
Australian Region 7 22232211
Darwin 5 2212221-
Townsville 9 23322-1-
Learmonth 8 22232312
Camden 6 22132211
Canberra 6 22132210
Hobart 7 22132221
Casey(Ant) 9 33322212
Observed Regional daily pc3 Indices 01 Jun :
Darwin 0 (Quiet)
Townsville 3 (Quiet)
Learmonth 8 (Quiet)
Alice_Springs 0 (Quiet)
Culgoora 20 (Quiet)
Camden 51 (Unsettled)
Gnangara 97 (Minor storm)
Canberra 57 (Unsettled)
Hobart 37 (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.
Estimated AFr/Ap Indices 01 Jun : A
Fredericksburg 6
Planetary 10
Observed AFr/Ap Indices 31 May : A K
Fredericksburg 8
Planetary 8 1222 3222
2B. MAGNETIC FORECAST
Date Ap Conditions
02 Jun 10 Mostly quiet to unsettled with the small chance
of isolated active periods and minor storm levels
at high latitudes.
03 Jun 8 Quiet to unsettled
04 Jun 6 Quiet
COMMENT: Mostly quiet to unsettled levels have been observed
across the Australian region during the past 24 hours with isolated
active to storm levels at high latitudes. Mostly quiet to unsettled
levels are expected for the next two days with isolated active
and storm levels possible at high latitudes for 2 June due to
the influence of a coronal hole solar wind stream. Geomagnetic
activity should be at mostly quiet levels for 4 June.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
01 Jun 2
Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Depressed by 20% during local day,
Near predicted monthly values during local night.
Northern Australian Region:
Mostly near predicted monthly values.
Southern Australian and New Zealand Region:
Near predicted monthly values during local day,
Enhanced by 30% during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Mostly near predicted monthly values.
Predicted Monthly T index for June: 6
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
02 Jun 0 near predicted monthly values/depressed 5 to
15%
03 Jun 0 near predicted monthly values/depressed 5 to
15%
04 Jun 5 Near predicted monthly values
COMMENT: Isolated depressions of 5-15% were observed at times
across the Aus/NZ region, otherwise MUFs were mostly near predicted
monthly values during the past 24 hours. Mostly normal conditions
are expected for the next few days with isolated depressions
of 5-15% possible at times. Spread-F and Sporadic-E conditions
were observed at times at most stations across the Aus/NZ region
during the past 24 hours and are possible at times during the
next few days.
