Abstract
One of three explored comets 9P/Tempel 1 was the main target of space mission Deep Impact. We present the results of exploration of spectra of three comets 9P (Tempel 1), C2004 Q1 (Machholz) and 37P/Forbes observed in 2004-2005 at Observatorio do Pico dos Dias (Brazil) and at Mount Pastukhov and Peak Terskol (Russia). The detailed identification of emission lines in spectra of comet 37P/Forbes was made. BVRI photometry comets 9P /Tempel 1) and C2004 Q1 (Machholz) was carried out. Physical parameters of C_2, C_3 and CN gases in the near nucleus region of the cometary atmospheres of comets 9P (Tempel 1), C2004 Q1 (Machholz) and 37P/Forbes were determined. Presence of cometary luminescence continuum (non-solar origin) in the spectra of three comets are confirmed.
