ISSUED AT 07/2330Z JULY 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 07 JULY AND FORECAST FOR 08 JULY - 10 JULY
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 07 Jul: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Jul: 71/6
1B. SOLAR FORECAST
08 Jul 09 Jul 10 Jul
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 70/5 70/5 70/5
COMMENT: Holloman Solar Observatory reported region 1024 (S28,W37)
has 13 spots and an area of 170 mils. There is still a slight chance
for this region to produce C-class flares over the next three days.
The solar wind ranged from 380 to 340 over the last 24 hours. A
coronal hole extends down to 25 degrees north latitude and may be
geoffective on 9 July.

Observed Regional daily pc3 Indices 07 Jul :
Darwin 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.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
07 Jul 2
Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Depressed by 15% during local day,
Near predicted monthly values during local night.
Northern Australian Region:
Mostly near predicted monthly values,
Southern Australian and New Zealand Region:
Mostly near predicted monthly values,
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Near predicted monthly values over the UT day.
Predicted Monthly T index for July: 6

08 Jul 6 near predicted monthly values
09 Jul 6 near predicted monthly values
10 Jul 6 Near predicted monthly values
COMMENT: MUFs remained mostly close to the normal values. Sporadic
E noted at Vanimo and Darwin. Some degradations in HF conditions
observed at high latitudes. Expect mostly normals values for
MUFs over the next three days.
