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.
