COMMENT: Variable MUF depressions of up to around 15% 
observed during both local day and night for Northern 
AUS/Equatorial regions with notable sporadic E at times. 
Ionosphere continues to remain weakly ionised due to very 
low solar activity. Similar HF conditions may be expected 
on 11 and 12 July with some possibility of further degradations 
on 13 July due to the possibility of rise in geomagnetic 
activity levels from 12 July.
