Received 17 March 1997 / Accepted 4 September 1997 Abstract We present V,I deep CCD photometry for three fields of the dwarf
galaxy in Sagittarius (Sgr), located at l=5.6o,
b=-14.1o. One of the fields is centered on the globular
cluster NGC 6715 (M54), which lies in one of the dense clumps of the
Sgr galaxy. Comparing the CMD of Sgr with those of globular clusters
which are believed to be kinematically associated with the dwarf
galaxy (Da Costa & Armandroff 1995), we conclude that the stellar
population of Sgr presents a spread in metallicity of -0.71
