Density differences and intensity syntheses based upon reference stars from the same plates are presented. The 12th mag blue supergiant (star 1) has two companions with V magnitudes, position angles, and separations 15.3, 315 deg, and 3 arcsec (star 2) and 15.7, 115 deg, and 1.5 arcsec (star 3), respectively. Both companions appear to be early-type stars; there is no evidence for a very red star in the system. The two companions are capable in principle of producing the current IUE spatial and spectral results, consistent with the interpretation that star 1 has disappeared.
