COMMENT: ASWFC SWF HF Communications Warning 79 was issued on 
6 September and is current for 6-8 Sep. Maximum usable frequencies 
(MUFs) in the Australian region were near predicted monthly values 
over 06-Sep. Enhancements of up to 30% were observed at Perth 
during local night hours. Spread F was observed at Hobart in 
the hours preceding local dawn. MUFs are expected to be mostly 
near predicted values over 07-09 Sep, with depressions possible 
at high latitudes over 08-09 Sep due to anticipated geomagnetic 
activity.
