COMMENT: Mostly normal HF conditions with isolated periods of 
minor depressions were observed across Australian/NZ regions 
today. Some degradation in HF conditions in the Australian/NZ 
region may continue to be expected on 22 and 23 September due 
to an expected rise in geomagnetic activity on these days. 
Mostly normal HF conditions may be expected in this region 
on 23 September.
