SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 2330UT/11 JUNE 2013 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 11 JUNE AND FORECAST FOR 12 JUNE - 14 JUNE
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 11 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 11 Jun:  90/34


1B. SOLAR FORECAST
             12 Jun             13 Jun             14 Jun
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    95/41              95/41             100/48

COMMENT: Solar activity is at Very Low levels. Currently there 
are two sunspot groups visible on the solar disc and activity 
is expected to remain at Very Low levels over the next few days. 
Solar wind ranged between 360 and 440 km/s over the last 24 hours 
with the interplanetary magnetic field Bz component ranging between 
-7/+5 nT. Noted CME on west limb first observed via SOHO LASCO 
C2 imagery at 0312 UT 11 June. Based on imagery from LASCO and 
STEREO, activity occurred around west limb and will not be geoeffective.

Observed Regional daily pc3 Indices 11 Jun : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)

      Gingin               0   (Quiet)
      Canberra             2   (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.

   Southern Australian and New Zealand Region:
      Near predicted monthly values during local day.
      Depressed 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 June:  67

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
12 Jun    60    Near predicted monthly values
13 Jun    60    Near predicted monthly values
14 Jun    60    Near predicted monthly values

COMMENT: Minor depressions possible over the next few days in 
the Australian region due to low solar EUV levels related to 
a low number of active regions.
