COMMENT: SWS HF Communications Warning 50 was issued on 30 October 
and is current for 31 Oct to 1 Nov. Normal to depressed MUFs 
were observed for the UT day, 31 October, in the Aus/NZ region. 
Current depressions are associated with low levels of ionising 
radiation and recent geomagnetic activity resulting in ionospheric 
storming. Expect normal to mildly depressed conditions to prevail 
for today, 1 November with some degradation in HF communication 
at high latitudes. Note, there were periods of sporadic E observed 
in the Australian region.
