Ultraviolet Spectra of Zeta Aurigae, obtained with the IUE satellite observatory prior to and through mid eclipse(phase .8-.05) are presented and interpreted according to the model proposed by Stencel and Chapman 1981. The profiles of various emission lines as a function of orbital phase through the eclipse are used to infer the conditions of the extended atmosphere and wind region of the K2II supergiant and the shocks resulting from the interaction of the B8V and K winds. The abundant profiles of Fe II are used to interpret the relatively cooler regions of the K star atmosphere while the profiles of C IV, Si IV and Fe III are used to reveal the structure of the hotter shock regions. The complex P Cygni profile of the Mg II resonance lines are identified as having components produced in the circumstellar, interstellar, and emission regions of the system.
