COMMENT: SWS HF Communications Warning 20 was issued on 3 December 
and is current for 3-4 Dec. Due to very low levels of ionising 
radiation from the Sun, MUF depressions of 15 to 20% were observed 
across the Australian region on UT day 3 December. Similar levels 
of MUF depressions in the Australian region are expected to continue 
on UT days 4-6 December.
