COMMENT: Maximum usable frequencies (MUFs) on UT day 09-Sep were 
mostly near predicted monthly values for the Australian region, 
with a brief mildly depressed period during local night, particularly 
at high latitudes. Spread-F was observed in Hobart and sporadic 
E was observed at Cocos Islands. Regional MUFs are expected to 
be near predicted monthly values over 10-12 Sep, with mild depressions 
possible due to coronal hole effects.
