COMMENT: IPS HF Communications Warning 26 was issued on 25
November and is current for interval 25-27 November. Some
MUF depressions were observed across the Aus/NZ regions over
the last 24 hours possibly due to weak ionisation as the
solar activity has stayed at very low levels for several
days. Nearly similar HF conditions may be expected in this
region over the next 3 days.
