COMMENT: IPS HF Communications Warning 34 was issued on 12 October 
and is current for 13-14 Oct. Ionospheric support continues to 
strengthen following recent geomagnetic activity, however MUF 
depressions continued during the local day in the S.Aus/NZ regions. 
Ongoing MUF depression of up to 20% are expected 13-Oct, predominantly 
in the S.Aus/NZ regions during local day time. Otherwise, mostly 
normal HF conditions are expected 13-Oct. Moderate degradation 
in HF conditions may be observed 14-15 Oct due to an expected 
increase in geomagnetic activity.
