COMMENT: IPS HF Communications Warning 49 was issued on 6 September 
and is current for 6-8 Sep. Due to very low levels of ionising 
radiation and effect of an increase in geomagnetic activity levels, 
mild to significant MUF depressions and degradations in HF conditions 
were observed over the last 24 hours in the Aus/NZ regions. Nearly 
similar HF conditions may be observed on 8 September with the 
possibility of some improvements through the following two days 
thereafter.
