  HIP 7666 is a variable star newly discovered during the Hipparcos mission and
classified as of unknown type (ESA 1997). During 23 nights between July 2000
and November 2000, over 2300 CCD observations in the V band were obtained from
Hostalets de Pierola and Monegrillo observatories in Spain. These data show
that the new variable is a detached eclipsing binary system with an orbital
period of 2.37229 days. In addition, one of the components undergoes very
short-period oscillations with a main pulsation frequency of 24.46 or 25.47
c/d. HIP 7666 is therefore a new member of the presently very few known
detached eclipsing binary systems with a Delta Scuti type component.
