IUE observation of Uranian emissions in hydrogen Lyman alpha (H Ly- alpha ) is considered. The purpose of this paper is to call attention to an important source not yet considered in these analyses, namely, the reflection of H Ly- alpha emissions from the interstellar wind (ISW). The calculations presented below demonstrate that the ISW source exceeds the solar source on the sunlit atmosphere of Uranus and in fact may comprise a substantial fraction of the observed intensity.
