Scientific paper

Photographic and spectroscopic observations of the galaxy NGC 6207 are presented. A photograph taken by the 120 cm telescope of the Haute Provence observatory reveals the nucleus 6 seconds south of the star studied by Weedman and Carswell (1974). The mass of the galaxy, calculated from image-tube spectra in the 6450-6800 A range, is given as 6.2 billion solar masses, with an M/L ratio of 0.8. The morphology of the galaxy, together with the relatively low values found for the mass and M/L ratio, suggest that NGC 6207 is an Sm rather than an Sc galaxy.
