COMMENT: IPS SWF HF Communications Warning 27 was issued on 15 
October and is current for 15-17 Oct. Max Useable Frequencies 
were slightly depressed across mid-latitudes due to slightly 
disturbed geomagnetic activity. They are expected to remain so 
on the 16th due to the glancing arrival of another coronal mass 
ejection, before recovery on the 17th. AR1865 has potential for 
M class flares and short wave fadeouts.
