COMMENT: SWS SWF HF Communications Warning 9 was issued on 28 
January and is current for 29-30 Jan. Australian regional maximum 
usable frequencies (MUFs) were near predicted monthly to enhanced 
values on 29 January. Mostly normal HF conditions expected for 
the next three days with a strengthening ionosphere due to extra 
ionising solar radiation from region 2936. MUFs generally above 
predicted monthly values by 10-25%. Possible shortwave fadeouts 
on daylight HF circuits over the next few days.
