ISSUED AT 24/2330Z NOVEMBER 2010 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 24 NOVEMBER AND FORECAST FOR 25 NOVEMBER - 27 NOVEMBER
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 24 Nov: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 24 Nov: 76/14
1B. SOLAR FORECAST
25 Nov 26 Nov 27 Nov
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 75/13 75/13 75/13
COMMENT: Solar activity was very low during the UT day today.
Solar wind speed ranged from 420 to 480 km/s over the last
24 hours and the Bz component of the interplanetary magnetic
field ranged between +/-4nT for most parts of the UT day today.
Solar activity is expected to stay at very low levels for the
next three days.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 24 Nov: Quiet to Unsettled
Estimated Indices 24 Nov : A K
Australian Region 7 12222232
Darwin 6 11222222
Townsville 8 2222232-
Learmonth 7 21222232
Canberra 7 12222232
Hobart 7 12222232
Casey(Ant) 10 ---32232
Observed Regional daily pc3 Indices 24 Nov :
Darwin 2 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 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 24 Nov : A
Fredericksburg 5
Planetary 6
Observed AFr/Ap Indices 23 Nov : A K
Fredericksburg 7

2B. MAGNETIC FORECAST
Date Ap Conditions
25 Nov 4 Quiet
26 Nov 4 Quiet
27 Nov 4 Quiet
COMMENT: Geomagnetic activity was mostly at quiet levels
today with isolated unsettled periods. Quiet conditions are
expected for the next three days.
-----------------------------------------------------------
3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
24 Nov Normal Normal Normal-fair
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
25 Nov Normal Normal Normal
26 Nov Normal Normal Normal
27 Nov Normal Normal Normal
COMMENT: Mostly normal HF conditions were observed over the
last 24 hours with some periods of minor depressions on high
and some mid latitude locations. Similar conditions may be
expected for the next three days as no significant variation
to the ionospheric conditions is expected during this period.

Depressed by 25% after local dawn.
Northern Australian Region:
Depressed by 15% during local day,
Near predicted monthly values during local night.
Southern Australian and New Zealand Region:
Depressed by 15% during local day,
Near predicted monthly values during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
25 Nov 0 near predicted monthly values
26 Nov 0 near predicted monthly values
27 Nov 0 near predicted monthly values
COMMENT: Mostly normal HF conditions with some periods of
minor MUF depressions were observed in the Aus/NZ region
over the last 24 hours. Nearly similar HF conditions may be
expected for the next 3 days for this region.
