New far ultraviolet spectra of Jupiter with a significant improvement in sensitivity and spectral resolution have been obtained from a sounding rocket by using a 10-channel spectrometer behind a pointing telescope. The major results obtained from these spectra are (1) a new measurement of the Jovian H I &lgr; 1216-¿ brightness (a comparison with other measurements indicates that the Ly &agr; emission is likely to be variable). (2) the measurement of the wavelength-dependent albedo for Rayleigh scattered solar radiation from ~1550 to 1875 ¿ with ~25-¿ resolution making it possible to set new upper limits on the abundances of some of the minor constituents in the upper Jovian atmosphere, and (3) a demonstration that weak emissions between ~1250 ¿ and near 1600 ¿ are probably the Lyman bands of H2 excited by low-energy electrons.
