COMMENT: IPS HF Communications Warning 6 was issued on 
7 November and is current for interval 8-10 November. HF 
conditions remained mostly at normal to fair levels on most 
locations on 09 November. Similar conditions may be expected 
for the next three days as no significant variations to the 
ionospheric conditions are expected during this period and 
the ionosphere remains relatively weaker due to continued 
low solar activity.
