Scientific paper

The eighth STEPHI international multi-site campaign was devoted to the δ Scuti Star V647 Tau of the Praesepe Cluster and was carried in the period 1997 Nov 19 - Dec 13. Analysis using two methods gave the same result. Five pulsation frequencies including both radial and non-radial modes are excited in this star. The dominant frequency p = 20.408c/d observed in 1972 has decreased to become the second frequency with a decreased amplitude. The global parameters show the star to be a young A type star just beginning core hydrogen burning.
