Objective-prism and objective-grating spectrograms were obtained in six star fields during the Gemini 11 mission. The grating spectra show absorption lines in the 2000 to 3000 angstrom wavelength region of Canopus and Sirius and provide ultraviolet-energy distribution data for approximately 50 stars. Many prism spectra show the Balmer discontinuity due to hydrogen and two absorption features probably due to ultraviolet iron multiplets.
