COMMENT: Maximum usable frequencies (MUFs) on UT day 27-Oct were 
near predicted monthly values. Spread F was observed during local 
night at Hobart and sporadic E was observed during local night 
at Learmonth and Cocos Islands. MUFs are expected to be near 
predicted monthly values over 28-30 Oct, with a chance of depressions 
at higher latitudes over 29-30 Oct due to coronal hole high speed 
wind stream effects.
