PRELIMINARY RESULTS OF STUDY OF COMET C/2020 F3 (NEOWISE)

Abstract

This paper presents the results of low-resolution spectral observations of the comet C/2020 F3 (NEOWISE). The emission lines in the spectrum of the comet, observed in the wavelength region λλ3800−7500, on July 20 and 27, 2020, were identified using the 2-meter telescope at Shamakhy Astrophysical Observatory. The wavelengths of 90 emission lines, including 31 emission lines from the carbon molecule C2, 40 from the NH2 molecule, 7 from CN, 4 from C3, 1 from CH, 2 from the water ions H2O+, and 3 unidentified lines were determined. Using approximately 110 visual magnitudes, the comet’s absolute magnitude was
calculated. The light curve of the comet was analyzed, and specific dynamic characteristics of the comet’s orbit were noted.
