COMMENT: SWS HF Communications Warning 13 was issued on 7 November 
and is current for 8-10 Nov. MUFs were depressed by 15-25% over 
much of the Southern Australian and Antarctic regions during 
UT day, 08 November, due to continued very low levels of ionising 
radiation. Periods of minor MUF enhancements were recorded in 
the Northern Aus regions. In the Aus/NZ region, expect near predicted 
MUFs to 40% depressions on UT day 10 November and near predicted 
MUFs to 30% depressions on 11 and 12 November.
