- Аннотация: We present the analysis of the polarimetric and spectral data obtained for the dynamically new comet C/2012 J1 (Catalina) when it was at a distance of 3.17 AU from the Sun. The observations were made at the prime focus of the 6-m BTA telescope using the SCORPIO-2 focal reducer. The map of the distribution of linear polarization in the cometary coma was constructed. The calculated value of linear polarization was on average about -2%. Spectral analysis of the cometary coma allowed to register the emission of the CN molecule in the (0-0) band. The gas production rate was derived using the Haser model and amounted to 3.7 × 1023 molecules per second.
