COMMENT: IPS SWF HF Communications Warning 29 was issued on 22 
October and is current for 23-25 Oct. HF conditions are still 
slightly enhanced due to high levels of ionising EUV flux from 
multiple sunspot regions. Expected geomagnetic activity over 
the next two days may reduce the maximum useable frequency from 
the currently enhanced levels, however at this stage conditions 
are not expected to drop significantly below the forecast monthly 
values. Possible SWFs over the forecast period.
