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.
