COMMENT: SWS HF Communications Warning 18 was issued on 26 November
and is current for 27-29 Nov. Due to the very low levels of ionising
radiation from the Sun, MUF depressions of 15 to 35% were observed
across the Australian region on UT day 27 November. Similar levels
of MUF depressions in the Australian region may be expected for
the next 3 days (UT days 28 to 30 November) as the levels of
ionising radiation are likely to stay at very low levels throughout
this period.
