2. FORECAST (04 SEPTEMBER - 06 SEPTEMBER)
Date   T index  Conditions       MUFs                              
04 Sep    60    Normal           Near predicted monthly values
05 Sep    55    Normal-fair      Near predicted monthly values    
06 Sep    50    Normal-fair      Near predicted monthly values 
                                 to 20% depressed   

COMMENT: Maximum usable frequencies (MUFs) on UT day 03-Sep were 
near predicted monthly values. Degraded conditions were observed 
in Darwin during local night. Sporadic-E was observed at most 
northern Australian sites and Cocos Islands. Regional MUFs are 
expected to be mostly near predicted monthly values to 20% depressed 
over 04-06 Sep, due to the combined effects from a coronal hole 
high speed wind stream and possible weak glancing blow from a 
CME first observed 02-Sep.
