COMMENT: HF conditions across Aust/NZ regions are expected to 
remain mostly normal during the next three days with some possibility 
of minor degradations in the southern region on 17 April due to 
a slight rise in geomagentic activity levels. Darwin showed local 
night sporadic E and Niue showed cases of sporadic E in the evening 
hours. HF conditions were degraded for Davis, Maquarie Island, and 
Mawson during the local night.
