COMMENT: Maximum usable frequencies (MUFs) in the Australian 
region on UT day 14-Sep were near predicted monthly values. MUFs 
are expected to be near predicted monthly values to depressed 
by up to 10% on 15-Sep and near predicted monthly values to depressed 
by up to 15% over 16-17 Sep. These depressions are due to anticipated 
geomagnetic activity and are more likely in the southern Australian 
region.
