Abstract: In this work we present the results from analysis of the Hα emission line observed at the primary minimum, at phases in the 0.0138 - 0.0263 range, when the disk was partly eclipsed by the mass losing star. The results indicate that the double peaked emission profile can be explained as being emitted in a large, eccentric disk around the primary component. This confirms the previous suggestions, based on photometric and spectroscopic data, that the disk in KU Cyg occasionally becomes very large, eccentric, and possibly precessing.
