SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 30/2330Z JANUARY 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 30 JANUARY AND FORECAST FOR 31 JANUARY - 02 FEBRUARY
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 30 Jan: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 30 Jan: 69/3
1B. SOLAR FORECAST
31 Jan 01 Feb 02 Feb
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 70/5 70/5 70/5
COMMENT: Solar activity remains very low and the solar disk has
no numbered sunspot regions. Presently the solar wind levels are
normal with the usual moderate IMF Bz north-south fluctuations.
Expect these conditions to prevail for the next three days.

Estimated Indices 30 Jan : A K
Australian Region 4 12121112
Darwin 5 21111113
Townsville 7 22222222
Learmonth 5 22120212

Observed Regional daily pc3 Indices 30 Jan :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (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.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
30 Jan -24
Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Depressed by 10% during local day,
Depressed by 30% during local night.
Northern Australian Region:
Depressed by 15% during local day,
Depressed by 20% during local night.
Southern Australian and New Zealand Region:
Depressed by 15% during local day,
Depressed by 20% during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Mostly near predicted monthly values over the UT day.
Predicted Monthly T index for January: 6
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
31 Jan -20 near predicted monthly values/depressed 10 to
20%
01 Feb -20 near predicted monthly values/depressed 10 to
20%
02 Feb -20 near predicted monthly values/depressed 10 to
20%
COMMENT: Sporadic E noted throughout the Australian region. Hobart
showed particularly strong sporadic E during the UT day. Macquarie,
Cocos, and Norfolk Islands showed particularly strong sporadic
E conditions during the local night. Expect mild depressions
to continue for the next three days in the low to mid latitudes
due to very low solar activity.
