COMMENT: MUFs were mostly near monthly predicted levels with 
sporadic minor depressions scattered across the Australian regions 
during UT day 14 February. The outlook for today (15 February) 
is for a slightly improved MUF conditions as the approaching 
coronal hole effects are expected to further enhance ionisation 
levels on the first day of storming. This is usually followed 
by storm-associated depressions on the subsequent days, possibly 
beginning from 16 February.
