Date   T index  Conditions       MUFs                              
03 Oct    45    Normal-fair      Depressed 10-15%/near predicted 
                                 monthly values
04 Oct    45    Normal-fair      Depressed 10-15%/near predicted 
                                 monthly values    
05 Oct    65    Normal           Near predicted monthly values   

COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
region on UT day 02-Oct were mostly near predicted values, with 
enhancements of up to 15% recorded in the northern Australian 
region and at Niue Island. Some sporadic E was observed at Darwin, 
Canberra, and Norfolk Island during local night hours. Scintillation 
was observed at Niue Island between 02/1052-1110UT, with an eightieth 
percentile S4 of 0.84. MUFs are forecast to become depressed 
by 10-15% over 03-04 Oct due to forecast geomagnetic activity. 
MUFs are then expected to trend toward predicted values by 05-Oct, 
as the geomagnetic activity subsides.
