Abstract:
    Based on photographic plates from the Harvard College Observatory, we
    have made 1492 magnitude estimates for the long-period classical
    Cepheid RS Pup (P=41.4d). Together with the observations taken from
    the literature, our data have allowed us to construct an O-C diagram
    spanning a time interval of 135-years.
