COMMENT: Averaged across all regions, ionospheric support for 
HF propagation was very close to predicted monthly values during 
19 September. Strong day time enhancements occurred at the Cocos 
Island and Niue Regions. Conditions were also moderately enhanced 
at the Perth Region for most of 19 September. Depressions at 
local dawn suggest that conditions may be depressed for some 
stations during 20 September.
