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.
