COMMENT: IPS HF Communications Warning 32 was issued on 6 October 
and is current for 8-9 Oct. HF conditions were normal over the 
first half of the UT day, with some degraded conditions occurring 
overnight, particularly in S.Aus/NZ locations, as a result of 
increased geomagnetic activity. MUFs remained mostly near predicted 
monthly values. Expect continuing degraded HF conditions 09-10 
Oct, with moderate MUF depressions, particularly at S.Aus/NZ 
locations, as a result of ongoing geomagnetic activity.
