COMMENT: ASWFC SWF HF Communications Warning 84 was issued on 
3 August and is current for 3-5 Aug. Maximum usable frequencies 
(MUFs) on UT day 03-Aug were near predicted values to 15% enhanced 
in the Australian region. Spread F was observed at Hobart during 
local night hours. Mild scintillation was observed at Darwin 
and Weipa 03/1000-1400UT. MUFs are expected to be near predicted 
monthly values to 15% enhanced. Mildly degraded HF conditions 
may be experienced during local night hours on 04-Aug for the 
southern Australian region. Shortwave fadeouts are probable.
