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.
