SUMMARY FOR 10 NOVEMBER AND FORECAST FOR 11 NOVEMBER - 13 NOVEMBER
STATUS INDICATORS SOL:GREEN   MAG:** RED **     ION: ** RED **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 10 Nov:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 10 Nov: 122/75


1B. SOLAR FORECAST
             11 Nov             12 Nov             13 Nov
Activity     Low                Low                Low

10.7cm/SSN   130/84             135/89             140/94

COMMENT: Solar activity was low over the last 24 hours, with 
several C-class flares. The largest of these was a C2 event at 
10/0504 from active region 1608 (S21W03). An associated CME observed 
in STEREO-A imagery at 10/0539 requires further analysis. Active 
region 1610 (S23E19) increased in spot count. The CME observed 
09/1454 is expected to arrive at Earth on 12-Nov. Solar activity 
is likely to remain low for the next 3 days, with a chance of 
M-class flares. The solar wind speed declined slightly and is 
now ~300km/s. The IMF Bz component was mostly neutral until ~15UT. 
Since then it has fluctuated from -4nT to +2nT.

Geomagnetic field for Australian Region 10 Nov: Quiet

Observed Regional daily pc3 Indices 10 Nov : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)

      Gnangara             0   (Quiet)
      Canberra             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.

Date      Ap    Conditions
11 Nov     5    Quiet
12 Nov    40    Minor Storm
13 Nov    30    Active to Minor Storm

COMMENT: Geomagnetic conditions were quiet over the last 24 hours 
and are expected to remain so on 11-Nov. Due to the expected 
arrival on a CME on 12-Nov (most likely in the first half of 
the UT day), minor storm level activity is predicted for 12-13 
Nov.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY


Date   T index
10 Nov    88

Observed Australian Regional MUFs
   Cocos Island Region:
      Enhanced by 25% during local day.
      Enhanced by 50% during local night.
   Niue Island Region:
      Mostly near predicted monthly values.
   Northern Australian Region:
      Mostly near predicted monthly values.
   Southern Australian and New Zealand Region:
      Mostly near predicted monthly values.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.

Predicted Monthly T index for November:  81

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
11 Nov    90    Near predicted monthly values
12 Nov    40    20 to 30% below predicted monthly values
13 Nov    30    20 to 30% below predicted monthly values

COMMENT: MUFs remained at near predicted monthly values with 
quiet geomagnetic conditions over the few days last and increased 
EUV flux. MUF depressions are likely from late 12-Nov due to 
expected CME arrival.
