2. FORECAST (01 SEPTEMBER - 03 SEPTEMBER)
Date   T index  Conditions       MUFs                              
01 Sep    20    Normal-fair      Near predicted monthly values
02 Sep    20    Normal           Near predicted monthly values    
03 Sep    20    Normal           Near predicted monthly values   

COMMENT: Maximum usable frequencies were mostly near predicted 
monthly values in the Aus/NZ region over the last 24 hours. Australian 
ionosonde stations showed isolated cases of sporadic E in the 
Australian region. Note possible degraded HF communication due 
to minor geomagnetic storming with possible minor depressions 
at higher latitudes, such as Tasmania on 01-02 September. Otherwise 
expect near predicted monthly MUFs in the Australian region for 
the next three days.
