COMMENT: 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 and an isolated enhanced period for
Equatorial regions. MUFs ranged from minor depressions to near
predicted monthly values during local night for Equatorial/Northern
AUS regions with Southern AUS/NZ and 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.
