COMMENT: IPS SWF HF Communications Warning 29 was issued on 22 
October and is current for 23-25 Oct. HF conditions are currently 
enhanced due to high levels of ionising EUV flux from multiple 
sunspot regions. Similar ionospheric conditions are expected 
for the next 3 days with a chance of SWFs.
