TWX 710-320-6842 ASTROGRAM CAM Telephone 617-495-7244/7440/7444 QSO 1146+111B,C M. A. Greenhouse, H. A. Thronson, Jr., G. L. Grasdalen and T. L. Hayward, Wyoming Infared Observatory, report observations of a suggested lensing object (Tyson and Gullixson 1986, submitted to Science) in the field of this double quasar. The object, at R.A. = 11h46h08s9 +/- 0s1, Decl. = +11deg05'35" +/- 1" (equinox 1950.0) has J = 17.2, H = 16.1, K = 16.0 (all +/- 0.2), consistent with an M giant.
