COMMENT: The pre-dawn depressions in MUFs on low latitudes, 
that are being observed for the last few days, are expected 
to continue for the next few days. HF conditions may show 
mild to moderate degradations on 29 October especially in 
the Southern Aus/NZ regions due to an expected rise in 
geomagnetic conditions during this period. Minor degradations 
in HF conditions in these regions may also be possible at 
times on 30 October.
