Descrição: We report here on unique post-perihelion (2.3 AU) measurements of Comet Hale-Bopp in the FUV-range (950-1250 Å) by means of the UVSTAR spectrometer from the space shuttle with the main purpose of searching for argon and other FUV emitters. New methods for separating the strong airglow emission at shuttle altitudes are here discussed in detail. Due to our low resolution (15 Å) and S/N ratio the possible rocket-borne detection of argon near perihelion (0.9 AU) could not be confirmed. New species as N^sub 2^ are suspected but difficult to separate from the strong airglow emission at shuttle altitudes. From the Lyα brightness (1.30± 0.08 kRy) a water production rate Q = 5.9 ± 0.4 × 10^sup 29^ molecules s^sup -1^ could be derived and compared with other post-perihelion observations.[PUBLICATION ABSTRACT]
