Spectral observations of the Giacobini-Zinner periodic comet
Abstract
A set of spectrograms of Comet Giacobini-Zinner obtained in the Crimea is presented. Swan bands C2(Delta-v = +2, +1.0, -1), as well as CN (0.1) and CH (0.0) are identified on the basis of these spectrograms; there are many CO, H2O(+), and H2 bands. Photometric measurements showed that the spectrophotometric gradient is equal to 5.1 and corresponds to the spectral class gK3 and color temperature 3674 K.
