COMMENT: SWS HF Communications Warning 49 was issued on 27 October
and is current for 28-30 Oct. Mildly depressed to depressed MUFs
were observed for the UT day, 27 October, in the Aus/NZ region.
Current depressions are associated with low levels of ionising
radiation and geomagnetic activity resulting in ionospheric storming.
Expect these conditions to prevail for the next three days with
some degradation in HF communication. Note there were periods
of sporadic E observed in the Australian region.
