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 on UT day 7-Sep were near predicted 
values to 15% enhanced. Spread-F was observed in Hobart during 
local night hours. MUFs are expected to be mostly near predicted 
values over 8-10 Sep, with some high latitude depressions of 
15% possible over 9-10 Sep due to anticipated geomagnetic activity. 
Degraded conditions may be observed over 8-10 Sep.
