COMMENT: MUFs on UT day 29 December were mostly near monthly
predicted levels with sporadic minor depressions scattered across
the Australian regions. The outlook for today 30 December is
for slight enhancements in MUF levels due to possible increase
in ionisation levels on Day 1 of anticipated storming associated
with the approaching coronal hole. On subsequent days (31 December
and 1 January), depression is MUFs are expected as the ionisations
loss processes spread equatorwards.
