COMMENT: IPS SWF HF Communications Warning 30 was issued on 25 
October and is current for 26-28 Oct. HF conditions are still 
enhanced due to high levels of ionising EUV flux from multiple 
sunspot regions. Expected geomagnetic activity 28-29 Oct may 
reduce the maximum useable frequency from the currently enhanced 
levels. MUFs expected to be near predicted monthly values with 
a chance of depressed periods for Southern AUS/NZ regions 28-29 
Oct. Short wave fadeouts possible next two days with a reasonable 
chance of isolated M and X flares from solar active regions.
