Scientific paper

Photoelectric surface photometry of the central area of the Leo II dwarf galaxy shows it to have a central surface brightness of V = 23.91 + or - 0.18 mag per sq arcsec and a color of B - V = 0.65 + or - 0.15. Its color is like that of a globular cluster rather than a giant elliptical galaxy. Using previously published structural data, an integrated luminosity can be calculated from the central surface brightness, giving V = 11.62 + or - 0.25. The absolute magnitude is thus M-nu = -10.2.
