COMMENT: HF conditions remained mostly at normal to fair 
levels on most locations on 13 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 very low solar activity.
