Abstract
Previous work has suggested that the very metal deficient giant stars are brighter in the near ultraviolet than are the corresponding model atmospheres. Observations of the star HD 122563 made with the IUE satellite suggest that this difference is less significant and may well be nonexistent at wavelengths less than 2700 A.
