2. FORECAST (08 NOVEMBER - 10 NOVEMBER)
Date   T index  Conditions       MUFs                              
08 Nov   -15    Normal-fair      Near predicted monthly values 
                                 to 20% depressed. 
09 Nov   -15    Normal-fair      Near predicted monthly values 
                                 to 20% depressed.     
10 Nov   -12    Normal-fair      Near predicted monthly values 
                                 to 15% depressed.    
COMMENT: General depressions in MUFs again observed across Australian/NZ 
region due to lack of solar ionising EUV. Sonde coverage across 
PNG and Pacific were intermittent but MUFs also assumed depressed. 
Spread F again widely observed. An anomalous enhancement was 
again observed across the Australian sector post dusk for 2-3hours 
before local midnight, followed by a deeper trough post midnight. 
More towards the north and reduced in amplitude compared with 
yesterday. Depressed MUFs compared with predicted monthly averages 
are expected to continue for the next 2 days at least. The new 
solar Region 973 is decaying and rotating off the solar limb 
and does not appear to have provided much ionisation.
