Abstract:
    Nearly 1000 nights of high-precision photometry of the delta Scuti
    variable 4 CVn were obtained from 1966 to 2012. These data led to the
    discovery of 64+ frequencies of pulsation together with systematic
    changes in amplitudes and small period changes on a timescale of
    decades. This paper presents the previously unpublished data.
