Scientific paper

CCD photometry in B and V, obtained at the ESO 2.2-m telescope, for a field in the Phoenix dwarf galaxy, is presented. The data indicate that the galaxy is dominated by an old metal-poor population, similar to that of the galactic globular clusters M3 and M92. The distance modulus is somewhat uncertain, but there are indications that the Phoenix dwarf galaxy belongs to the Local Group. A small amount of stars of a young population is also present. It is suggested the Phoenix dwarf galaxy is a dwarf spheroidal galaxy in which a second recent burst of star formation has occurred.
