MUSICOS 1996 campaign was held in Nov. 15 - Dec. 2. Five telescopes were involved in this campaign, 1.93m telescope at Haute-Provence Observatory, INT at La Palma, 2.1m telescope at McDonald Observatory, CFHT at Hawaii and 2.16m telescope at Xinglong Station of Beijing Astronmical Observatory. Four targets, SU Aur, AB Aur, xi Per and V480 Tau were observed during the campaign. For the delta Scuti star V480 Tau, total of over 300 high S/N ratio and high resolution spectra were obtained during five nights. As we know, the delta Scuti line-profile variables represent potentially very good candidates for seismological investigations into the structure of main sequence and slightly more evolved A- and F-type stars (e.g., Walker et al 1987, Kennelly et al 1992a, Kennelly et al 1992b). The good time coverage observation makes it possible to carry out time series analysis as well as the "Dopplor Spatial" analysis of the line profiles so that we can identify some high modes of nonradial pulsation. At this moment, the data reduction is being done. The preliminary result will be presented in this paper.
