COMMENT: MUF depressions persisted longer than expected local day yesterday, 
probably in association with southwrad IMF conditions. In particular 
strong depressions were observed in Northern Australia during 
local night hours. Regional MUFs for today are initially expected 
to be 10-15% depressed recovering as the day progresses. A general 
trend of improving HF conditions remains expected.
