2. FORECAST (14 SEPTEMBER - 16 SEPTEMBER)
Date   T index  Conditions       MUFs                              
14 Sep    15    Normal           Near predicted monthly values
15 Sep    10    Normal-fair      Near predicted monthly values    
16 Sep    10    Normal           Near predicted monthly values   

COMMENT: MUFs were mostly near predicted monthly values over 
the last 24 hours in the Australian/NZ region, with minor enhancements 
in the Southern Australian Region. HF conditions in Australian/NZ 
region are expected to be between slightly enhanced and near 
monthly predicted values for the next three days due increased 
solar ionising radiation and forecasted active conditions. High 
latitudes experienced poor HF conditions most likely due to PCA 
effects after increased proton levels.
