COMMENT: Maximum usable frequencies (MUFs) varied mostly between
near predicted monthly values and mildly to moderately depressed
ones on UT day 02 December. The depressions were due to low levels
of solar ionising flux. Sporadic-E occurrences were seen over
some sites. For the next three UT days, 03-05 December, mildly
depressed to near predicted monthly MUFs are expected over the
Australian region.
