COMMENT: Mostly normal HF conditions in the Aus/NZ region over 
the last 24 hours. Some degraded HF conditions were observed 
at higher latitude sites (Hobart, south). MUFs were near predicted 
monthly values in the S.Aus/NZ/Antarctic regions and depressed 
to 20% in N.Aus. Variable depressions of up to 40% were observed 
in the equatorial region. MUFs are expected to be mildly depressed 
(10 to 20%) next three days due to continuing low solar activity.
