COMMENT: Significant MUF depressions continued across all 
S.Aus/NZ/Antarctic sites 11-Oct, as the ionosphere slowly 
recovers from a period of sustained geomagnetic activity. 
Mostly normal HF conditions may be expected for the next 
2 days. Minor to moderate degradations in HF conditions 
may be observed on the third day due to an expected rise 
in geomagnetic activity levels on the third day.
