We report the variations of the UV spectrum of BP Tau from 5 to 19 January, 1992 when the star was monitored with IUE during 2 rotation periods. Our data indicate that lines that can be excited by recombination processes, such as those from O I and He II have periodic-like light curves, whereas lines that are only collisionally excited do not follow a periodic-like trend. These results agree with the expectations of the magnetically channelled accretion models.
