COMMENT: Mostly normal HF conditions observed over the last 24 
hours. Depressed periods during local day for Northern AUS/Equatorial 
regions with notable sporadic E. Normal conditions for Southern 
AUS/NZ regions with continued enhancements during local night. 
Ionospheric support for Antarctic regions ranged between normal 
and poor. Similar conditions are expected for the next 3 days 
with periods of MUF depressions ranging from 10%-20% due to low 
solar activity having diminished ionospheric influence.
