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 20% on UT day 30 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 31 October - 2 November).
