Low-resolution spectrum of comet C/2004 Q2 (Machholz)

Abstract

We analysed the spectroscopic data for comet C/2004 Q2 (Machholz), obtained on the Zeiss-600 telescope in Andrushivka Astronomical Observatory on January 29, 2005. The observed spectrum covers a wavelength range 3600-9200 Å with a spectral resolution of 6.2 Å. The molecular-line features of C₂, C₃, CN, NH₂, CH, H₂O⁺, and CH⁺ were found in the spectrum.
