We have measured the intensities of a large number of permitted and forbidden emission lines in four zones of the central part of the galaxy. We detect faint CII and OII recombination lines, the first time that these are unambiguously detected in a dwarf starburst galaxy. The physical conditions of the ionized gas have been derived using a large number of different line intensity ratios. Description: The observations were made on 2003 March 30 with the Ultraviolet Visual Echelle Spectrograph (UVES) at the Very Large Telescope (VLT) Kueyen unit in Cerro Paranal Observatory (Chile).
