COMMENT: SWS HF Communications Warning 10 was issued on 28 October 
and is current for 29-31 Oct. MUFs over the Australian regions 
were mainly from near monthly predicted levels to depressed by 
around 35% on UT day 29 October. Very low levels of ionisation 
radiation from the Sun seems to be the main reason for these 
MUF depressions. Minor depressions to near monthly predicted 
MUFs are expected in the Aus/NZ regions for the next three days 
(UT days 30 October - 1 November).
