THE first detection of H2in the Sun, in extreme ultraviolet spectra, is reported Here. The Naval Research Laboratory's High Resolution Telescope and Spectrograph (HRTS), flown in a rocket on 21 July 1975, was used for these observations. The slit extended from Sun centre to limb and crossed a sunspot at 07° S, 23° W in McMath region 13766. This stigmatic spectrograph, described by Bartoe and Brueckner1, covered 1,175–1,714 Å with 0.06 Å spectral and 1.5 arc s spatial resolution. A full list of observed lines is in preparation2. The sunspot spectrum contains some 120 emission lines which do not correspond to known lines listed in compilations3of transitions in atoms or ions, apart from random coincidences. More recent publications referred to in the NBS Bibliography4were also consulted. The identifications of the lines which are enhanced in the sunspot spectrum will be discussed elsewhere5. |
