COMMENT: IPS HF Communications Warning 33 was issued on 9 October 
and is current for 10-11 Oct. Significant MUF depressions and 
degraded HF conditions were observed across all low-, mid-, and 
high-latitude sites 09-Oct, as a result of sustained geomagnetic 
activity. Expect continuing degraded HF conditions 10 Oct, with 
moderate-strong MUF depressions, particularly at S.Aus/NZ locations, 
as a result of ongoing geomagnetic activity.
