Scientific paper

We report on the discovery of Cepheid variables in the South Polar (Sculptor) Group galaxy NGC 247. The periods, colors and mean magnitudes of these stars were determined from BVRI CCD observations obtained between 1985 and 1992 at Cerro Tololo Inter-American Observatory (CTIO) and at Las Campanas Observatory (LCO). Light curves, period-luminosity relations, reddenings and a true distance modulus to NGC 247 will be presented. JHC was supported by NASA Grant NAG8-998, and by and NSF Research Opportunity Award; WLF was supported in part by NSF grant AST 91-16496.
