COMMENT: HF conditions are expected to remain mostly near
normal levels across most parts of Aus/NZ regions for the
next three days with the possibility of minor to moderate
degradations in conditions and some MUF depressions in the
northern parts of this region due to weak ionospheric
ionisation due to continued very low levels of solar activity.
