This contract pertained to the investigation of the time variability of the ultraviolet continuum flux of three stars: lambda Eri, 53 Persei, and gamma Cas. The Voyager observations of 53 Persei were conducted simultaneously with a global ground-based campaign of visual-wavelength photometry. The optical campaign established beyond doubt the existence of two nonradial pulsation modes with periods near two days. The second part of the program concerned the ultraviolet continuum modulations of the B2E star lambda Eri. Voyager observations of lambda Eri showed that the ultraviolet light curve of lambda Eri shows no variations over a timescale of a day, but may show excursions on the order of an hour. There was little actual overlap between the Voyager and the IUE datasets in time so we could not determine whether the short-term variations from Voyager are instrumental or from the star. The third and final part of the program concerned the ultraviolet continuum variations of the B0.53 star gamma Cas. The Voyager observations of gamma Cas show that 10-20% variations occur on a timescale of 1-2 hours and are commonplace.
