SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 2330UT/09 SEPTEMBER 2013 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 09 SEPTEMBER AND FORECAST FOR 10 SEPTEMBER - 12 SEPTEMBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 09 Sep:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 09 Sep:  94/40

1B. SOLAR FORECAST
             10 Sep             11 Sep             12 Sep
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    90/34              90/34              95/41

COMMENT: Only region 1838 (S04 E17), a single spot, on the visible 
disc. A filament erupted from the north-west quadrant and was 
associated with a weak CME which is unlikely to be geo-effective. 
ACE data show the solar wind speed undisturbed. Wind speed is 
expected to increase on 11 Sep due to a recurrent coronal hole.

Observed Regional daily pc3 Indices 09 Sep : 
      Darwin               8   (Quiet)
      Townsville           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 International Center for Space Weather 
Science and Education, Japan.
