Abstract

A sounding rocket observation of G191-B2B, a hot white dwarf star, was made on 27 September 1999 over a wavelength range of 220 - 340 angstroms with the Extreme ultraviolet Opacity Rocket (EOR), an EUV spectrograph. EOR acquired over 200 seconds of data above 200 km. Two broadband multilayer- coated diffraction gratings in Wadsworth mounts provide EOR with a peak effective area of 2.5 cm² near 280 angstroms and spectral resolution of (lambda) /(Delta) (lambda) equals 2500 - 3000. Preliminary examination of the flight spectrum suggests the presence of absorption features which are not apparent in lower resolution spectra.
