The IUE observations of y 1 Vel suggest that we are dealing with an interacting binary system with nonthermal energy sources and perhaps two regions of high electron temperature. The ultraviolet continuum fits the Kurucz LTE model atmosphere computations for T e ~ 20,000 K and logg ~ 3, parameters which are in order for a B2 III star, i.e., for the trum of y 1 Vel as observed in the photographic region.
