COMMENT: IPS HF Communications Warning 27 was issued on 27 November 
and is current for interval 28-29 November. Some MUF depressions 
were observed in the southern 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. Further depressions 
in MUFs may be possible in Souther Aus/NZ regions on 29 November 
due to some possibility of enhancemd geomagnetic activity on 
this day. Mostly normal HF conditions may be expected for the 
following two days thereafter.
