Emission from the carbon star CIT 6 in the J = 1-0 spectral lines of CO and HCN was observed with the Crimean Astrophysical Observatory RT-22 radio telescope during 1984-1985. Differences between the present spectra and those obtained earlier suggest that the molecular radio emission of CIT 6 may be variable. The angular dimension of the HCN emission region in CIT 6 is about 25 arcmin; the relative abundance of HCN molecules in the CIT 6 envelope is greater than about 10 to the -8th.
