COMMENT: MUFs were mostly near monthly predicted levels with
sporadic minor depressions scattered across the Australian regions.
The two day outlook (29-30) December) is for similar MUF conditions
as the ionosphere continues to recover from the 26 December coronal
effects. The approaching coronal hole is expected to initially
further enhance ionisation levels on 30 December, followed by
storm-associated depressions on the subsequent days.
