COMMENT: SWS HF Communications Warning 15 was issued on 14 November 
and is current for 14-16 Nov. HF conditions for the AUS/NZ region 
during the last 24 hours saw MUFs depressions ranging between 
10%-30% during local day for all latitudes. MUFs ranged from 
minor depressions to near predicted monthly values during local 
night for Equatorial, Northern AUS and Southern AUS/NZ regions. 
Antarctic regions near predicted monthly values. Similar levels 
of depressed ionospheric support expected for the next 3 days 
with minor to moderate MUF depressions across all latitude bands 
due to continued very low levels of ionising radiation from the 
Sun.
