Scientific paper
More than eight years of IUE observations of Be stars were analyzed. Results show that variability is an outstanding property of the far UV spectrum of Be stars. This variability is best seen in the C IV resonance lines which show: remarkable changes in profile and velocity, as well as in the presence, location, and strength of narrow absorption components; large variations in strength going from strong to undetectable lines; and variability patterns associated with those exhibited by the Balmer emission lines.
