The quasars 1146+111B,C were observed at red wavelengths to increase the database on the objects to determine if they are the same quasar with two images produced by a gravitational lens. Previous data showed that the objects, visually separated by 2.6 arcmin, have similar redshifts. The new data, collected simultaneously for both quasars with the 3.6 m telescope at La Silla, covered the spectra range 5600-9300 A. Significant differences were observed in the 4340, 4102 and 6301 lines, suggesting that the objects are separate quasars which are relatively close together, as evidenced by the redshift data.
