We present two-color photometric data obtained by the MACHO collaboration on a binary lensing event first analyzed by Udalski et al. (1994). We show that our independent data not only support the binary interpretation of the event, but also provide strong additional constraints on the models. In particular, the source size is well resolved from the second peak in the light curve. We will discuss the uniqueness of the model fits and various physical constraints on the models.
