Date   T index  Conditions       MUFs                              
01 Dec    -5    Normal           0 to 10% below predicted monthly

COMMENT: Mostly normal HF conditions were observed across Aus/NZ 
mid-latitude regions over the last 24 hours with averages slightly 
below monthly medians but a small post dusk enhancement at many 
stations. Similar conditions may be expected for the next 3 days 
with a slight overall increase to near predicted monthly median 
levels in 1-2 days if geomagnetic activity is enhanced by a coronal 
hole induced high speed solar wind stream.
