Three-color photometry of the 1981 eclipse of the long-period binary RZ Oph is presented. The data are combined with those of Baldwin (1978) to improve the determination of the times of contacts. A solution assuming i = 90°, similar to Baldwin's, leads to the conclusion that the cooler star does not fill its Roche lobe. A solution similar to Smak's (1981), which assumes that this star does fill its lobe, is also possible, but leads to a value of k = 0.022±0.001, which is hard to reconcile with the stars' spectral types, relative visual luminosities, and bolometric corrections. This leaves unanswered the questions of the origin of the material in the disk surrounding the hotter star, and of the evolutionary state of the system.
