Coma spectra of Comet Halley
Abstract
Typical coma spectra of Comet Halley were obtained on 1985 December 25 and 1986 January 13 using the 1 metre telescope of the Yunnan Observatory. The nitrogen-baked Kodak plates showed a continuum with strong molecular bands in emission. The intensity ratios are found to be CN(4216A)/C 3(4052A) = 1.03 , CN(4216A)/C2(4365A) = 1.00 .
