SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 28/2330Z AUGUST 2010 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 28 AUGUST AND FORECAST FOR 29 AUGUST - 31 AUGUST
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 28 Aug: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 28 Aug: 72/8
1B. SOLAR FORECAST
29 Aug 30 Aug 31 Aug
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 72/8 72/8 75/13
COMMENT: Solar wind speed ranged between 530-680 km/s and will
slowly decrease then probably rise late on day three due to the
effects of a recurrent coronal hole. The north-south IMF component
ranged between +4/-3 nT. Region 1101 (N12E20) has grown slightly
in area but is stable.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 28 Aug: Quiet to unsettled.
Active levels observed at higher latitudes.
Estimated Indices 28 Aug : A K
Australian Region 7 22322121
Darwin 6 22222121
Townsville 10 32332222
Learmonth 6 22222221
Canberra 5 22222011
Hobart 6 21232111
Casey(Ant) 11 34422132
Observed Regional daily pc3 Indices 28 Aug :
Darwin 17 (Quiet)
Townsville 2 (Quiet)
Learmonth 2 (Quiet)
Alice_Springs 0 (Quiet)
Gnangara 28 (Quiet to unsettled)
Canberra 25 (Quiet to unsettled)
Hobart 34 (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.
