Abstract
The observations and research of the long periodic comets C/2014 Q2 (Lovejoy) and C/2013 US10 (Catalina) by optical spectra with an average resolution (λ/Δλ ≈ 1200) are presented. The spectra were obtained in February and December 2015 using the telescope AZT–14 (D = 0.48 m, F = 7.7 m) and the spectrograph ASP–9 at the station Astronomical Observatory of Taras Shevchenko National University of Kyiv “Lisnyky”. On the basis of obtained spectral material was carried the identification of spectral emission bands. Calculated some physical parameters of neutral gas cometary atmosphere and dusty cometary atmosphere. Built distribution of general and reflected energy along the slit of the spectrograph. Calculated flows,the number of molecules and gas productivity for basic molecular emissions, relative dust productivity.
