COMMENT: ASWFC SWF HF Communications Warning 128 was issued on 
4 November and is current for 4-6 Nov. Maximum usable frequencies 
(MUFs) in the Australian region on UT day 04-Nov were generally 
near predicted monthly values to 15% enhanced. MUFs at Darwin 
were enhanced by up to 40% during local night hours. Shortwave 
fadeouts impacting lower HF frequencies were observed during 
the intervals 04/0054-0253UT, 04/0342-0351UT, 04/0413-0418UT 
and 04/0432-0437UT. MUFs are expected to be near predicted monthly 
values to 15% enhanced over 05-07 Nov. Shortwave fadeouts are 
probable.
