TitlePaper, 'On the spectra of comet a 1890 and the nebula G C 4058' by J [Joseph] Norman Lockyer
DescriptionLockyer writes: 'The comet discovered by Mr. Brooks on the 19th of March (a, 1890) has recently been observed at Kensington with the view of testing the sequence of spectra which resulted from my discussion of all the spectroscopic observations of comets which had been made up to the end of 1888. The orbit, however, is such that the comet has only passed through a small range of temperature, and no changes have been observed in its spectrum beyond the gradually increasing brilliancy of the carbon bands relatively to the continuous spectrum. As I pointed out in the paper referred to, the citron band should be most variable, for the reason that the brightest flutings in the spectra of manganese and lead fall near it; but, although this band has been carefully observed on every occasion, it has retained the same wavelength, and was found by direct comparisons to be coincident with the carbon band near λ 564.'
