COMMENT: HF conditions in most parts of Austalian/NZ regions
were mostly near normal with periods of MUF depressions and
degradations in HF conditions possibly due to a weaker ionosphere
due to continued very low solar activity. Nearly similar HF
conditions may be expected for the next three days as no
significant variations are expected in the ionospheric conditions
during this period.
