SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 07/2330Z MARCH 2010 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 07 MARCH AND FORECAST FOR 08 MARCH - 10 MARCH
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 07 Mar: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Mar: 77/16
1B. SOLAR FORECAST
08 Mar 09 Mar 10 Mar
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 80/20 80/20 80/20
COMMENT: Solar activity was Very Low over the the last 24 hours
with only minor B-class events. Very Low solar activity is expected
over the next 3 days. Solar wind speed was 380km/s at 00UT, increased
to 430km/s beteween 03UT-09UT and then decreased to be 380km/s
at the time of this report. The Bz component of the interplanetary
magnetic field was southward between 03UT-04UT at -10nT and then
decreased in magnitude to range between +/-2nT from 09UT onwards.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 07 Mar: Quiet to Unsettled
Estimated Indices 07 Mar : A K

Darwin 3 22210002
Townsville 6 22321111
Learmonth 4 22211011
Canberra - --------
Hobart 7 23321111

Observed Regional daily pc3 Indices 07 Mar :
Darwin 2 (Quiet)
Townsville 0 (Quiet)

Alice_Springs 0 (Quiet)
Gnangara 2 (Quiet)
Canberra NA
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 07 Mar : A

COMMENT: Geomagnetic activity was mostly Quiet over the last
24 hours with Active conditions for high latitudes between 00UT-09UT.
Quiet to Unsettled conditions are expected over the next 24 hours.
Possible Unsettled periods for mid to high latitudes 09Mar and
Quiet conditions expected 10Mar.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
07 Mar 29
Observed Australian Regional MUFs
Cocos Island Region:
Near predicted monthly values during local day,
Enhanced by 20% during local night.
Niue Island Region:
Enhanced by 30% during local day,
Enhanced by 20% during local night.
Northern Australian Region:
Enhanced by 15% during local day,
Enhanced by 20% during local night.
Southern Australian and New Zealand Region:
Enhanced by 15% during local day,
Enhanced by 15% during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Near predicted monthly values over the UT day.
Predicted Monthly T index for March: 7
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
08 Mar 20 Near predicted monthly values to enhanced 10
to 20%.
09 Mar 15 Near predicted monthly values to enhanced 10
to 20%.
10 Mar 15 Near predicted monthly values to enhanced 10
to 20%.
COMMENT: Enhanced HF conditions observed for Australian and NZ
regions over the last 24 hours. MUF's enhancements of ~20% due
to consistently strong EUV from current active sunspots observed
during local day and night for Northern AUS/Equatorial regions
and Southern AUS/NZ regions. Mostly normal ionopheric support
for Antarctic regions. Notable sporadic E observed for Northern
AUS regions between 09UT-14UT. Mostly normal HF conditions are
expected for the next 3 days. Enhanced MUF's of 10%-20% for low
to mid latitudes 08Mar and MUF's near predicted montly values
for 09Mar and 10Mar.
